[The capacity to destinguish changes in the intensity as a function of volume and frequency (author's transl)].
Békésy audiometry equipment was used for investigations carried out in 15 test persons to study the intensity differentiation threshold. We tried to find the degree of intensity required to recognize given dB changes in the intensity. The results achieved very well coincide with those established by other authors. It was possible to statistically prove the volume dependence of the intensity differentiation threshold, it was, however, not possible to establish any frequency dependence. The relations of our result with the SISI test are under discussion.
