Hearing impairment is a major indicator for assessing the hazards of noise to human beings. In order to implement hearing protection for workers, many countries have stipulated that they should conduct regular audiological examinations on their employees, such as the Occupational Safety and Health Administration (OSHA) on May 29, 1981 The promulgated hearing protection plan stipulates that workers exposed to noise above 85 dB (A) perform annual audiological tests to detect significant auditory impairments and take measures to treat the well.
