Abstract
The papers devoted in the literature to the subject of the perception of frequency changes most often deal with research on the perception of frequency modulation or its changes of linear character, or the evaluation of the pitch of a signal with frequency varying in time. Within the range of these problems, an interesting question, so far not undertaken, is that of the perception of jump frequency changes occurring in a decaying signal, quite frequent in practice. In view of this, research was undertaken with the essential purpose of determining the thresholds of perception by listeners of single and double frequency changes (jumps) occurring in a decaying signal with an exponential envelope, depending on: the duration of these changes, their mutual time interval and the position of these changes with repect to the onset of the signal. The results obtained indicated a strict relation between the course of the thresholds of the perception of jump frequency changes, depending on the time parameters of these changes.References
