AbolishedAcoustics--Statistical distribution of hearing thresholds as a function of age
声学 听阈与年龄关系的统计分布
Application Summary AI generated
This standard provides statistical data on the expected hearing threshold levels for otologically normal persons in a specified population, as a function of age and gender. It is applied in occupational health and audiology contexts to establish baseline hearing levels for noise-exposed workers, enabling the calculation of noise-induced hearing loss by comparing an individual's measured hearing to the age-predicted norm. The standard is also used in product design for hearing aids and personal audio devices to ensure appropriate amplification levels for different age groups.
