[Temporal summation in masking and speech recognition].

Temporal summation in masking has been measured simultaneously with a resolution of the masker's spectral structure to find psychoacoustic characteristics for estimation of speech intelligibility, to detect the manifestation of peripheral processes in auditory perception in humans. For this, detection thresholds of a test signal with different durations were determined. The test signal was pulse with a Gaussian envelope and a sine-wave carrier.

[Manifestations of dynamic coding of the amplitude-modulated sounds on the level of auditory nerve fibres].

Average firing rate of the auditory nerve fiber as function of the level of the tone with the frequency equal to characteristic frequency of the fibers, can be defined as an input-output characteristic. It is known that the steepening of the input-output characteristic of the real auditory nerve fiber is more, and the width is less than the spontaneous activity of the fiber. The latter characterizes fiber's ability to generate spikes, if the stimulus is absent.
