Environmental noise regulations usually specify a maximum outdoor noise level of 60 to 65 dB(A), while occupational safety organizations recommend that the maximum exposure to noise is 40 hours per week at 85 to 90 dB(A). For every additional 3 dB(A), the maximum exposure time is reduced by a factor 2, e.g. 20 hours per week at 88 dB(A).

The Dangerous Decibels program promotes the use of "Jolene" mannequins to measure output of PLSs as an educational tool to raise awareness of overexposure to sound through personal listening. [23] This type of mannequin is simple and inexpensive to construct and is often an attention-grabber at schools, health fairs, clinic waiting rooms, etc. [23]
The discomfort threshold is the loudness level from which a sound starts to be felt as too loud and thus painful by an individual. Industry workers tend to have a higher discomfort threshold (i.e. the sounds must be louder to feel painful than for non-industry workers), but the sound is just as harmful to their ears. [33]
Cranking up the volume is putting more than a billion 12- to 34-year-olds at risk of hearing loss. Researchers shared their analysis of data from 2000 to 2021 on unsafe listening practices in the ...
How loud is too loud in Texas neighborhoods? Here’s what to know.
Sounds that seem loud to humans often emit high-frequency tones that can scare away dogs. Whistles which emit ultrasonic sound, called dog whistles, are used in dog training, as a dog will respond much better to such levels. In the wild, dogs use their hearing capabilities to hunt and locate food.
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 ...
