There is no agreement on the acceptable risk of noise-induced hearing loss in children; and adult damage-risk criteria may not be suitable for establishing safe listening levels for children due to differences in physiology and the more serious developmental impact of hearing loss early in life.
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).
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 ...

There are a wide variety of symptoms that have been found to be associated with sensory overload. These symptoms can occur in both children and adults. Some of these symptoms are: Irritability "Shutting down," or refusing to participate in activities and interact with others; Over-sensitivity to touch, movement, sights, or sounds
Most children naturally learn their native language at a young age. [28] Although spoken language is ubiquitous for children who hear normally, congenitally deaf children do not have access to it from birth. Less than 10% of the children with hearing loss are born into deaf families who use sign language as their main communication method. [29]
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.
An Exposure Action Value (EAV) or Action Value (AV) is a limit set on occupational exposure to noise where, when those values are exceeded, employers must take steps to monitor the exposure levels. These levels are measured in decibels. The American Occupational Safety and Health Administration (OSHA) set the EAV to 85 dB(A).
