Stress from time spent around elevated noise levels has been linked with increased workplace accident rates, aggression, and other anti-social behaviors. [11] The most significant sources are vehicles, aircraft, prolonged exposure to loud music, and industrial noise. [12] Prolonged exposure to noise at home has been linked to decreased mental ...
Loud noise exceeding levels that can damage hearing is regularly encountered by commuters using buses, subways and even biking, a Canadian study suggests.
When sensorineural hearing loss (damage to the cochlea or in the brain) is present, the perception of loudness is altered. Sounds at low levels (often perceived by those without hearing loss as relatively quiet) are no longer audible to the hearing impaired, but sounds at high levels often are perceived as having the same loudness as they would for an unimpaired listener.
By listening to broadband noise at soft levels for a disciplined period of time each day, some patients can rebuild (i.e., re-establish) their tolerances to sound. [ 2 ] [ 47 ] [ 48 ] [ 49 ] More research is needed on the efficacy of sound therapy techniques when hyperacusis is the primary complaint, rather than a secondary symptom, indicating ...
Loud music and barking dogs were the leading causes of noise complaints made by a city's residents about their neighbours in the past year. More than 160 people were the subject of enforcement ...
A study of occupational and recreational noise exposure at indoor hockey arenas found noise levels from 81 dBA to 97 dBA, with peak sound pressure levels ranging from 105 dB SPLto 124 dB SPL. [75] Another study examined the hearing threshold of hockey officials and found mean noise exposures of 93 dBA.
A loud boom Saturday night left people worried throughout Elk Grove, and police are working to determine what might have happened. The unexpected noise startled residents around 10:30 p.m., Elk ...
Noise-cancelling headphones and sound-isolating earphones can help one avoid turning the volume up to overcome loud background noise. Sound measurement apps can help one find out how loud sounds are. If not measuring the sound levels, a good rule of thumb is that sounds are potentially hazardous if it is necessary to speak in a raised voice to ...
