A re-examination of the hearing-threshold distribution is reported through statistical distribution method to show a more precise profile of auditory sensitivity at high frequencies. A mathematical transformation of threshold to improve the fitness of individual thresholds to a normal distribution is also proposed. Selected percentiles of threshold distribution that are estimated using the transformation are presented in a tabular and graphical form. It is found that for frequencies of 10 kHz and higher, the threshold distribution fits a normal distribution after a power-transformation of individual thresholds and is estimated more accurate. It is found that the percentile thresholds reported should be consulted for those frequencies when the hearing sensitivity of a person is examined in composition to the general population.
