What EPA considered excessive noise?
The document identifies a 24-hour exposure level of 70 decibels as the level of environmental noise which will prevent any measurable hearing loss over a lifetime. Likewise, levels of 55 decibels outdoors and 45 decibels indoors are identified as preventing activity interference and annoyance.

What are the controlling methods of noise?
Extraction, ventilation, cooling, openings in walls and enclosures. Instead of fitting silencers, it is often possible to achieve a 10 – 20 dB reduction in airborne noise from a duct or opening by lining the last bend in the ductwork with acoustic absorbent (foam or rockwool / fibreglass).
How can you protect yourself from excessive sound?
Use hearing protection devices (such as earplugs and earmuffs) when you cannot avoid loud sounds. Make hearing protection convenient. Stash earplugs in your car or workshop for easy access. Keep children away from loud music or equipment at home.

The fact that you can’t see, taste or smell it may help explain why it has not received as much attention as other types of pollution, such as air pollution,…
What should my noise level be after control?
The desired (least annoying) octave band frequency spectrum for which to aim at the location of the exposed worker is shown in Figure 10.1 for an overall level of 90 dB(A). If the desired level after control is 85 dB(A), then the entire curve should be displaced downwards by 5 dB.
How does a noise measurement system take place?
The SLM takes the sound pressure level at one instant in a particular location. To take measurements, the SLM is held at arm’s length at the ear height for those exposed to the noise. With most SLMs it does not matter exactly how the microphone is pointed at the noise source.
Where does the noise come from on an air conditioner?
In most new air conditioners, the bulk of the noise comes from the compressor. You can remove the top of your A/C outdoor unit and install a sound blanket over the compressor — it just sits right on top of it. This will muffle much of the sound of the unit.

An air conditioner making a pulsating noise isn’t necessarily a bad sign — a little pulsing noise can be perfectly normal when the air conditioner is operating. But if your outdoor A/C unit is making a pulsating noise that you can hear from inside the house, it could be a sign that something has come loose inside the unit and needs to be replaced.
How are noise levels measured in a workplace?
Where possible, noise levels should be evaluated at locations occupied by workers’ ears. Normally the noise control program will be started using as a basis A-weighted immission or noise exposure levels for which the standard ISO 11690-1 recommends target values and the principles of noise control planning.
