A noise that is rated at 57 dB is generally considered to be relatively quiet, and is unlikely to cause any long-term damage to a persons hearing. What happens when attempting to record sounds higher than a microphones max SPL rating? This is a little louder than a normally humming refrigerator, which is typically around 40 decibels, and slightly quieter than normal talking, which is around 60 decibels. The decibel scale is logarithmic, meaning it increases by the power of 10 each time. Sound is measured in decibels (dB). More details about this topic can be found on the NIOSH Science Blog Understanding Noise Exposure Limits: Occupational vs. General Environmental Noise. But, if you move further away, it will sound softer even though it does not decrease in intensity.

To put this into perspective, at 65db, a person would need to raise their voice to be heard by someone standing one meter away from them. The U.S. Environmental Protection Agency (EPA) and the World Health Organization (WHO) recommend maintaining environmental noises below 70 dBA over 24-hours (75 dBA over 8-hours) to prevent noise-induced hearing loss. Exposure time is especially important since, for every 3 dBAs over 85dBA, the permissible exposure time before possible damage can occur is cut in half which is very drastic when you think about it. How loud is 55 decibels example? Want the quickest way to expand the number of subjects you can record? Possible damage in 8 hour exposure.

Title: Microsoft Word - E1ECEEFE.doc However, long-term exposure to noise can be just as damaging as the short-term, as demonstrated in the table below taken from The Control of Noise at Work Regulations act 2005. This is a device that uses a condenser microphone to measure the changes in air pressure from sound waves. When discussing how loud something is in dB, people are often referring to the dB Sound Pressure Level, which is often shortened to dB SPL. What level of sound is safe for human ears? Sound intensity is the amount of sound energy in a confined space. Free SLMs developed as smartphone apps are available. How Do I Prevent Hearing Loss from Loud Noise? The dB scale is logarithmic, meaning that a 10 dB increase actually means that the sound level perceived is doubled and a 10 dB decrease means that the sound level perceived is halved.

Humans can hear the average range of sound from 0 to 140 dB; anything above 140 decibels can cause severe pain and damage. A whisper is about 30 dB, normal conversation is about 60 dB, and a motorcycle engine running is about 95 dB. When sound waves cause the air pressure to change, the movement of the microphones diaphragm is converted to an electric signal (in volts), and translated into sound pressure levels (decibels dB SPL) which is displayed on a screen of the instrument. This is when researchers from Bell Telephone Laboratories attempted to make an anechoic chamber. The acceptable decibel level for residential areas usually varies from state to state and country to country.
