Many communities use the Maximum Permissible Sound Levels criterion (see below), with a correction for the character of the sound. Illinois sets maximum blasting levels by land use zone and in three time categories. Portland, OR (Section 18.10.010.F) limits levels to 100 dB (peak) from 7 am to 10 pm and 80 dB (peak) from 10 pm to 7 am.
However, when users raise the volume to the maximum level, the standard specifies that an alert should pop up to warn the listener of the potential for hearing problems. [31] The 2018 ITU and WHO standard H.870 [30] "Guidelines for safe listening devices/systems" focus on the management of weekly sound-dose exposure. This standard was based on ...
Noise can be an annoyance that creates fatigue and negatively affects productivity, safety and the ability to communicate. Therefore, standard methodologies for quantifying noise have been developed. Noise curves reflect different standardized means of creating a single number rating for the background noise spectrum in a space.
Noise may be measured using a sound level meter at the source of the noise. [23] [24] [25] Alternatively, an organization or company may measure a person's exposure to environmental noise in a workplace via a noise dosimeter. [26] The measurements taken using either of these methods will be evaluated according to the standards below.
The Noise Pollution and Abatement Act of 1972 is a statute of the United States initiating a federal program of regulating noise pollution with the intent of protecting human health and minimizing annoyance of noise to the general public. [1]

Hearing conservation programs [1] are programs that should reduce the risk of hearing loss due to hazardous noise exposure, if implemented correctly and with high quality. . Hearing conservation programs require knowledge about risk factors such as noise and ototoxicity, hearing, hearing loss, protective measures to prevent hearing loss at home, in school, at work, in the military and, and at ...
