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.
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 ...
The passive system works to stimulate the inner hair cells directly and works at levels above 40 dB. [4] At stimulation levels that prevent the excitation of the passive system, prolonged noise exposure results in a decrease in the loudness heard over time, even when the actual intensity of the noise has not changed.

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).
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.

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]
An infant or toddler is potentially vulnerable to physical abuse, sexual abuse, psychological abuse and neglect and has inability to verbalize the details of the abuse. [23] Child grooming can be a concern and occurs when a perpetrator wins the trust of caregivers for the purpose of creating an opportunity for them to sexually abuse an infant ...
