The impact of genetic factors of the decay of the acustic function has been studied. Various tonal frequencies have been tested on a sample of 16 MZ and 16 DZ twin pairs, belonging to both sexes and to different age groups, i.e., fourth, fifth, and sixth decade.

A relatively high heredity coefficient is found with respect to the fourth and fifth decade.
