This International Standard provides descriptive statistics of the hearing threshold for populations of otologically normal persons of various ages under monaural earphone listening conditions. It specifies the following, for populations within the age limits from 18 years to 80 years inclusive for the range of audiometric frequencies from 125 Hz to 8 000 Hz: a) the expected median value of hearing thresholds given relative to the median hearing threshold at the age of 18 years; b) the expected statistical distribution above and below the median value. For the frequencies from 3 000 Hz to 8 000 Hz, the median and statistical distribution for populations above 70 years are presented for information only. This International Standard also provides for information the expected median values at audiometric frequencies from 9 000 Hz to 12 500 Hz within the age limits from 22 years to 80 years inclusive. The data are applicable for estimating the amount of hearing loss caused by a specific agent in a population. Such a comparison is valid if the population under study consists of persons who are otologically normal except for the effect of the specific agent. Noise exposure is an example of a specific agent and for this application selected data from this International Standard are referred to as “database A” in ISO 1999.
