Abstract

The use of representative percentiles of normal hearing-threshold distribution in a tabular form are discussed. The researchers calculate the standard deviation (SD) of hearing thresholds as a function of frequency from 25Hz to 18Hz. Using the SDs and normative threshold values of the ISO standard, the normal threshold distribution profile could determine the entire range of audible frequencies. Thus it can be concluded that a table of representative values of threshold distributions can be more convenient to use than the mean and SD values.
