Building Vibration Limits in Indonesia

Tác giả Bởi Michel
Ngày đăng Tháng 6 26, 2020

A lot of activities and businesses have the potential to have negative effects to their environment because of the vibration that they produce. For example, construction (for example during piling), mining and and other vibration-generating activities. This vibration can disturb the comfort and health of people around it, and even can have destructive effects to nearby buildings.

In Indonesia, the vibration limit is regulated through Ministerial Decree of Ministry of Environment No. 49 Year 1996. This regulation was made to ensure healthy environment for human and other living creatures to live in. Consequently, the vibration generated from human activities need to be regulated.

In this regulation, businesses and activities are required to:

Comply to the vibration limit in the decree. This is required for businesses and activities to obtain certain relevant permits to be able to operate.
Use vibration reduction equipment
Report vibration monitoring activities at least once in 3 (three) months to the Governor, Minister, Government agencies that are responsible to control environmental impact, other technical institutions that is responsible for the activities and other organizations that might need the vibration monitoring report.

The vibration limit is separated into few parts which are:

Vibration limits for health and comfort
Mechanical vibration limits based on its destructive effects
Mechanical vibration limits based on building types
Shock limits

The following table and graphs is the vibration limit for health and comfort:

Conversion:

Acceleration = (2πf)² x displacement

Velocity = 2πf x displacement

The graphic representation of the table above is as follows:

The table below is the vibration limits based on the destructive effects:

As seen above, the peak velocity limit from the vibration is separated into 4 categories which are:

Category A: non-destructive

Category B: Possibly destructive for plastering (crack, or in certain cases the plaster can fell off the wall)

Category C: Possibly destructive for structural components that bear loads

Category D: High risk of destruction of load bearing walls

The following graph is the vibration limit based on destructive effects in a graphical form:

Mechanical vibration limit can also be categorized into the types of buildings. The buildings are categorized into 3 which are:

Buildings for commercial, industrial, and other similar use.
Residential and other buildings with similar design and usage
Structures that are sensitive to vibration and cannot be categorized into category 1 and 2, for example preserved buildings with high cultural value

Below is the vibration limits for the building category above:

The table below is shock limit for buildings:

Category	Building Type	Maximum velocity (mm/s)
1	Old buildings with high historical value	2
2	Buildings with existing defects, cracks can be seen on the walls	5
3	Buildings with good condition, minor cracks on plaster is acceptable	10
4	Buildings with high structural strength (for example industrial building which is made from concrete and steel)	10 – 40

The ministerial decree also describe the measurement and analysis method for vibration as follows:

Instruments:
1. Vibration transducer (Accelerometer or seismometer)
2. Vibration measurement device or analysis device (Vibration meter or vibration analyzer)
3. 1/3 octave or narrow band filter
4. Signal recorder
5. FFT Analyzer
Measurement procedure:
1. Vibration measurement related with health and comfort:
  - Place transducer on the floor or other vibrating surface, and connect it to the measuring device with filtration
  - Set the measuring instruments to measure displacement. If the measuring instruments do not have that on display, the conversion from acceleration or velocity can be used
  - Reading and recording is conducted for frequency between 4-63 Hz or with signal recording device
  - Measurement results with at least 13 data shall be plotted on graph
2. Vibration measurement for structural health:
  - The measurement method is similar with the vibration measurement above, however the physical measure that is assessed is the peak velocity.
3. Evaluation
  - The 13 data which are plotted on graph shall be compared with the vibration limits. The vibration is considered above the limit if the vibration level exceeds the limit at any frequency.

Definition

The definition used in the regulation of ministry of environment No 49 Year 1996 is as follows:

Building structure is a part of building that is planned, calculated, and functioned to:
- Support any kind of load (static load, dynamic load, and temporary load)
- Functioned for building’s stability as a whole. For example: frame and bearing wall
Structure’s component is a part of a building structure that contributes to structure’s function. For example: beams, columns, and slab.
Bearing wall is a building structure which is a vertical plane that is functioned to support loads on top of it such as slab or roof.
Non-structure components are parts of building that is not planned or functioned to support load. For example partition walls, door and window frames, etc.

Destructive impact on structure and non-structure:

Destructive impact on structure: Destructive impacts that can endanger building stability (for example destruction of columns that potentially make a building collapses)
Destructive impact on non-structure: Not dangerous to building stability, but can be a danger for building occupants (for example: when a partition wall collapses, it will not make the building collapse, but can injure occupants)

Degree of building destruction:

Light: not dangerous for building stability and can be fixed without reducing building’s strength
Moderate: Destruction that can reduce structural strength. To fix this, added reinforcement must be used.
Severe: Degree of destruction that can endanger the building and potentially makes the building collapses.

Noise Level Prediction in Industry (Oil & Gas, Power Generation, Process, etc.)

Tác giả Bởi Michel
Ngày đăng Tháng 5 4, 2020

Most industrial activities create noise that can be harmful to the environment as well as to their workers. To minimize this effect, governments, associations, and companies have created regulations, standards, and codes to set the allowable noise both inside the sites, that can be harmful to the workers, as well as to the environment. In a lot of cases, during the planning phase, the plant owner and project management want to be sure that the noise levels are acceptable. Since the plant is not built yet, what can be done is creating a noise model to simulate the plant, so that the noise levels can be predicted. In this article, we will explore how we can do so.

The first thing we must know is how much noise does the noise sources inside of the plant will emit. The noise source is usually described in two ways which is Sound Power Level (Lw or SWL), and Sound Pressure Level (Lp or SPL) in certain distance, most commonly Lp in 1 m distance. There are multiple ways to get this information for certain noise sources. First, if the equipment type and model have been chosen, the equipment manufacturer will normally report the noise level in their datasheet. However, this is not usually the case with most of noise predictions since the noise study is normally done before the equipment suppliers are appointed. So, the second way to be able to predict the noise emission is by following empirical formulas that are developed by researchers. You can find such formulas in some textbooks, journals, and papers. For rotating parts, you will need its rated power and rotational speed to be able to estimate the noise emission.

For example, in the speed range of 3000-3600 rpm, the noise level of a pump with drive motor power above 75 kW can be predicted using the following equation:

Suppose a pump with rotational speed of 3000 rpm and 100 kW, according to the formula, it can be estimated that the noise level at 1 m from the pump would be 92 dB. And suppose the noise source can be considered as point source on the ground (hemisphere propagation), the sound power level of the pump can be calculated using the following formula:

Where r is the distance from source to receiver

And in this case, the predicted Lw would be 100 dB.

Thirds, noise measurement to a similar equipment can also be an option to be able to determine the noise level of the new equipment. Another option, in some countries, there are noise emission limit for certain equipment, you can use that limit if it is applicable for your project.

After the Lw of all noise sources is obtained, we want to calculate the noise levels (the Lp) at the receivers. There are some standards which procedure can be followed to calculate this. Few of which are ISO 9613-2, NORD 2000, CNOSSOS EU, and many others. Most of the standards consider some factors to the calculation such as distance, atmospheric absorption, ground reflection, screening effect (from barriers and obstacles) and other factors such as volume absorption from vegetation, industrial site, etc. Most consultants and projects will require a software such as SoundPLAN to do this calculation.

Depending the project, there are few types of noise limit which compliance will need to be ensured. The most common ones are environmental noise limit, noise exposure limit, area noise limit and absolute noise limit. Besides, the noise level during emergency is also modelled so that the information can be used for safety and PAGA (Public Address and General Alarm) study.

Environmental noise limit is usually calculated for the plant’s contribution to the plant’s boundary as well as to the nearest sensitive receiver such as residential and school near the plant. How this is accessed depends on the regulation applicable on the plant area. In Indonesia for example, the noise limit for residential area is Lsm 55 dBA and industrial area is Lsm 70 dBA. Lsm is a measure like Ldn, but the night noise level addition is 5 dB instead of the 10 dB addition that most other countries, especially Europeans use. To ensure compliance with this regulation, the noise level at fence should be less than Lsm 70 dBA, and suppose there is a residential area nearby, the contribution from the site should be less than 55 dBA. It is also advisable to measure the existing noise level at the sensitive receivers to make the study more relevant to the situation.

Noise exposure limit is the maximum exposure to noise that the workers get during their working period. In Indonesia, the noise exposure limit is 85 dBA for 8 working hours. To change the working hours, 3 dB exchange rate is used. For example, if the noise level in the plant is 88 dBA, then the workers can only work there for 4 hours, if it is 91 dBA, then the time limit is 2 hours, and so on. To extend the working hours on a noisy area, the options are to actually reduce the noise level by reducing the noise emission from the source or noise control at transmission (for example using barrier), or by usage of Hearing Protection Device (HPD) for the workers such as ear plugs and ear muffs. The noise exposure of workers after usage of HPD can be calculated using the following formula:

Where NRR is the noise reduction rating of the HPD in dB.

Different area might have different noise level limits, and therefore area noise limits are useful. For example, in an unmanned mechanical room, the noise level can be high, for instance 110 dBA. However, inside of the site office, the allowable noise level is much lower, for example 50 dBA. This noise level shall be calculated to ensure compliance with the noise limit. Different companies might have different limits for this to ensure their employees’ health and productivity. If the area is indoor and the noise source is outdoor, then the interior noise level can be estimated using standards such as ISO 12354-3.

The absolute noise limit is the highest noise level allowable at the plant, and shall not be exceeded at any times, including emergency. In most cases, the absolute noise limit for impulsive sound is 140 dBA. To ensure compliance with this requirement, potential high-level noise shall be calculated, for example safety valves.

During emergency, different noise sources than normal situation will be activated, such as flare, blowdown valves, fire pumps, and other equipment. In such cases, the sound from the alarm and Public Address system must be able to be heard by the workers inside of the plant. Normally the target for the SPL from the PAGA system should be higher than 10 dB above the noise level. Therefore, the noise level during emergency in each area should be well-known.

Coronavirus Lockdown Gives Animals A Rare Break from Noise Pollution

Tác giả Bởi Michel
Ngày đăng Tháng 4 22, 2020

The COVID-19 lockdown could become an unprecedented natural experiment in noise pollution. Some of the world’s most vocal animals — birds and whales — might already be benefiting from a quieter environment.

While a drop in transportation during the coronavirus lockdowns has led to lower pollution levels across the world, the slowdown in traffic has also lowered another big polluter: noise.

According to the World Health Organization (WHO), noise pollution affects over 100 million people across Europe and, in Western Europe alone, road traffic accounts for premature deaths equivalent to the loss of roughly “1.6 million healthy years of life.”

Take the disturbance to human health out of the equation, and noise remains a big source of pollution for the other inhabitants of the planet as well, namely, animals.

But how much have animals in countries on lockdown really benefited from the drop in noise levels? Turns out, that’s a very difficult question to answer.

Birds will benefit the most

Birds — by far the most visible animals found in cities, and the most vocal — stand to be among the biggest beneficiaries of quieter streets and parks.

The signals birds send each other through song is a means of survival. Without the ability to sing, hear and be heard, birds would have a difficult time finding a mate or defending their territory from predators.

There are reports of seeing more birds during the lockdown. Ornithologists say this is due to increased awareness of people’s surroundings while at home

Human activity influences bird behavior, even prompting them to communicate at less ‘busy’ times of day

The swift rise of human-made noise — also known as anthropogenic noise — over the past century has made this harder for birds.

Just like humans who have to speak up in a loud setting, birds, too, have to sing louder to communicate properly in today’s noisy world, according to ornithologist Henrik Brumm, who heads the research group for the communication and social behavior of birds at the Max Planck Institute for Ornithology near Munich.

“This happens really fast,” Brumm told DW. “We found out that it takes roughly 300 milliseconds, so less than 1 second, for birds to readjust when the level of noise rises. So, when their surroundings become louder, they sing louder, too.”

Are birds getting quieter? Maybe.

Birds are already known to sing more quietly in the early morning hours of the weekends, says Brumm. The reason: there’s less traffic to compete with.

With Europe on lockdown, Germany for its part, has seen passenger air travel slashed by over 90%. Moreover, car traffic has dropped by more than 50% and trains are running at less 25% their usual rates.

A recent study from the Max Planck Institute also suggests that chronic traffic noise can have a negative effect on embryo mortality and growth in zebra finches. This, in turn, could mean that the current lockdowns coinciding with mating season could lead to not only more, but also healthier hatchlings. That is, as long as their parents choose a spot that’s still safe from humans after the lockdown ends.

Though it’s difficult to speculate without real-time data, Brumm says, it stands to reason that the current period of quiet could mean birds might be singing more softly than usual, which would already be a huge benefit.

At land or sea, noise is bad news for animals

Birds aren’t the only animals that stand to benefit from less noise. According to a recent study published in the journal Biology Letters, noise pollution affects any number of creatures ranging from frogs, to shrimp, to fish, mammals, mussels and snakes.

In fact, another habitat garnering more and more attention for noise pollution is the ocean. As bioacoustics expert Christopher Clark described it in with Yale’s environmental magazine, the din from oil and gas activity, for example, is filling entire ocean basins with “one big storm of noise.”

While research on noise pollution and marine life, just like with ornithology, is in its early stages, a landmark study conducted in the days after 9/11 found that less shipping traffic seemed to make whales calmer.

Examining the feces of right whales — a species of baleen whale that can reach 15 meters in length and weigh up to 70 tons — researchers found that fewer ships in the waters along the US-Canadian coast correlated with lower stress hormones.

The noise levels from shipping traffic, whose 20–200 Hz hum disturbs sea life despite being a low frequency, decreased by 6 decibels, with a significant reduction below 150Hz .

An unprecedented time for researchers

Just like ornithologists, marine life researchers have also found correlations between noise and interruptions in behaviors like foraging and mating. Whales, like birds, also “mask.” That is to say, they sing louder to be heard over noise disturbances, be they high or low frequency sounds.

“It’s really a huge footprint that these activities have in the ocean,” according to Nathan Merchant, an expert on noise and bioacoustics at the UK’s Centre for Environment, Fisheries and Aquaculture Science (CEFAS).

Source: https://www.dw.com/

And the sources of noise pollution — ranging from shipping, to wind farms, to the sequence of powerful blasts from seismic air gun tests used to locate oil and gas deposits in the ocean deep — are even harder to escape in the ocean than on land.

“It has a lot to do with how sound travels under water. Sound can travel much further and much faster than in air,” Merchant told DW.

Instruments off the coast of North America, for example, can detect seismic air gun testing as far away as the Brazilian coast.

With many cruises suspended, oil freighter traffic impacted by an oil price crash and rig activity being run by skeleton crews to curb the spread of COVID-19, marine biologists could potentially find a treasure trove of data once they’re allowed to go back into the field.

“We have underwater noise recorders at sea as we speak, but they aren’t cabled to land. So, we’ll find out when get out on a ship in several months’ time and get the data back,” Merchant said.

The more interesting question by that point might be how marine life responds to a sudden reintroduction of the human cacophony after an unexpected period of rest.

Is it the construction site, a nearby railway or an aircraft?

Noise, Nuisance or Danger

Tác giả Bởi Michel
Ngày đăng Tháng 10 28, 2019

As an introduction to this question some basic facts about noise.

Basic noise facts

Noise is typically defined as ‘unwanted sound’. The unit for sound is the Decibel which is a value calculated with logarithms from the pressure to get a scale from 0 to 120 dB where 0 dB is the hearing threshold for a young person with healthy hearing and 120 dB is the pain threshold.

We can state that noise is a type of energy created by vibrations. When an object vibrates it causes moment in air particles. The particles will bump into each other and will generate sound waves, they are ongoing until they run out of energy.

High and low tones are perceived by our hearing due to fast and slow vibrations.

Sound needs a medium to travel and the speed of sound is around 340 meter per second. Examples of typical noise levels:

Due to the nature of the calculation of Decibels we cannot just add them together.

Examples:

3 dB + 3 dB = 6 dB

But…..

10 dB + 10 dB is not 20 dB but 13 dB

The Decibel (sound pressure level) for sound in air is relative to 20 micro pascals (μPa) = 2×10⁻⁵ Pa, the quietest sound a human can hear.

The human hearing system

The human hearing system is capable of hearing sounds between 20 Hz and 20000 Hz. Below 20 Hz is called infra sound and above 20000 Hz is called ultrasounds. Both infra- and ultrasound is not audible for us. Elephants however can hear frequencies as low as 14 Hz and bats can hear frequencies up to 80000 Hz.

A special noise weighting for the human perception has been introduced in the 1930’s and called the A-weighted Decibel, dB(A). This was introduced to align the noise levels with the sensitivity and physical shape of the human hearing system.

Basic human hearing system

When sound waves enter the ear, they travel up the ear canal and hit the ear drum, the ear drum will vibrate and the three smallest bones in the human body will transfer these vibrations to the fluid in our inner ear’s sensory organ the cochlea. The sensory hair cells will vibrate which will send nerve impulses to the brain, the brain will translate these impulses for us and we perceive sound!

Dangers of noise

Noise from certain music can be a very pleasurable sound for one person and a horrific noise for another. From this fact we can see that noise is not only an absolute value but also strongly depending on the receiver’s mindset.

However, there are some clear absolute values concerning the danger levels of noise.

Generally accepted as safe is spending 8 hours per day in an environment not exceeding 80 dB(A)
NOT safe would be to spend 1 hour in a disco with levels at 100 dB(A) which are easily exceed nowadays

Apart from the obvious hearing loss there are many other issues that can arise from exposure to (too) high noise levels such as:

Hypertension
Heart disease
Annoyance – stress
Immune system – psychosomatic

The positive side to remember is that Noise Induced hearing loss is 100% preventable!!

Worldwide solutions

Governments (especially in Europe) know the actual cost of high noise exposure and they concluded that protecting their citizens from high noise exposure (during working hours, recreation as well as during sleep) is far more effective than dealing with the costs of citizens enduring high noise related illnesses, demotivation, sleep disturbance etc.

They are investing in quiet schools (optimal learning environment), quiet hospitals (patients recover a lot faster in quiet wards), implement city planning to create quite zones.

Of course, they also have strong noise regulations that are being enforced.

Acoustical societies worldwide help to create awareness and leverage noise legislations with governments.

Noise in Asia

I have been living in Asia for the last 15 years and of course I noticed it’s noisy. Noise regulations (if exist at all) are very lenient and mostly not enforced. I’m very happy to see that Acoustical Societies are coming up in Asian countries and can convince governments to invest in setting up proper noise regulations and enforcing them. I’m very happy to be able to contribute to a quieter world by creating more awareness for the dangers of noise!

Fog up technology can be described as convenient atmosphere for holding and processing information, combining hardware, licensed software, interaction channels, in addition to technical support meant for users. Operate the “clouds” is aimed towards reducing prices and maximizing the effectiveness of corporations. A feature associated with cloud technology is the lack of attachment to the hardware platform and physical area, the potential of scalability. Your client can work using cloud services from all over the world and from any gadget with Internet access, quickly interact to changing business tasks belonging to the enterprise together with market demands.

With the help of due diligence data room virtual data room due diligence , a virtual storage space is hired, so the boss can totally control most hosted providers, regardless of provider. It is easy to develop a virtual speak to center on the particular network, so that you can save on hiring a room and organizing jobs. Work may start two days following your application is normally submitted to the provider. Cloud services for business are used to produce a virtual business office , that is, businesses will not be linked with a specific laptop or computer. In the “cloud” is reproduced the internal community of the provider, that is, it provides disks, folders, and applications for preparing.

Why are data room providers used during banks?

The competition amongst banks is certainly huge but not everyone can hold up against during times of desperate. Such banks are beginning to put on innovative solutions to reduce costs. Cloud storage services are aimed at robotizing financial processes. As a result, there is an increase in typically the efficiency of credit corporations by lowering the cost of confirming. It is important to remember that since there is a new risk of thieves entering the particular cloud storages, they do not retail outlet customer data.

In virtual data rooms , there is a make sure all documents with which you worked usually are saved in fact: employees cannot accidentally or perhaps intentionally erase them, if an error was made in the kept changes, they could always be rolled back to the previous version with the file. Many services not just save replicates of documents, but also the entire folder construction that users are used to seeing on their pcs. The number of gizmos that we utilization in everyday life is growing: computers, laptop computers, tablets, cell phones. Often all of us use units from distinctive manufacturers with different software fillings. For the operational solution regarding business complications, it is necessary to get access to relevant working documentation via any of the gadgets of different suppliers.

A virtual data room is a ready-made computing resource without the expense of the getting physical gear and its obama administration. You get a swimming pool of virtual resources (processors, memory, hard disk drive space) that you control with the web panel. Create digital servers together with networks with the necessary settings, install any kind of system plus application program. You can on their own control the access and even rights of numerous people plus groups of staff and associates to your files and records of kind of.

Should I spend money on data room providers?

To be able to use all of the features of some sort of virtual data room (automatic your own, uninterrupted functioning during product updates, higher availability of apps under basket full, etc . ), you are best ordering an enterprise move to the particular cloud out of international service providers. This will allow anyone to properly design the infrastructure required for your own product, make it along with minimal expense and automate its preservation to ensure optimum efficiency.

An individual agreement totally free services stipulates that the provider reserves the justification to provide access to your information kept in its impair at the get of government businesses. Corporate impair services offer differentiation involving access degrees: if designed correctly, your data will not be obvious to any employee of the cloud storage. You may also store info in protected form. If you want to use cloud storage exclusively in the form of some sort of “virtual expensive drive”, you can opt for free options. But if you intend to combine such remedies into your business and care about security, you will have to pay designed for advanced operation and usability.

Ngày đăng Tháng 8 21, 2019

Allahabad, Aug 20 The Allahabad High Court on Tuesday asked the Uttar Pradesh government to ensure that no noise pollution rules are violated in the state, saying the breach of decibel limits would be treated as the violation of fundamental rights of citizens.
A bench of justices P K S Baghel and Pankaj Bhatia gave the direction on public interest litigation by one Sushil Chand Srivastava, an Allahabad native.

Srivastava had moved the court alleging that huge LCD screens have been put up all over the city and they emanate sound beyond permissible decibel limits and cause noise pollution since early in the morning till late into the night.

The petitioner submitted to the court that authorities have failed to enforce the law as well as various directions of the Supreme Court on the menace of the noise pollution.

Taking note of the allegations, the court asked authorities to categories the cities in the state into industrial, commercial, residential or silence zone for regulating noise pollution in the state.

The court also entrusted the responsibility of implementing various laws and bylaws, rules and regulations relating to the noise pollution in their jurisdictions to the station house officers of various police stations and the circle inspectors.

The court also directed its registry to send a copy of its order to the state chief secretary for its compliance.

“Any breach of the Noise Pollution Rule, 2000 shall be treated to be the violation of the fundamental right of a citizen,” the court added.
