[Effect of tone intensity and frequency on discrimination of the transition process of the acoustic stimulus].
The discrimination threshold for the stimulus rise time is 1.5 msec in low and middle frequency range and increases abruptly up to 5-6 msec in the range of 10-15 kHz. The threshold of detection of the square waveform depends on the stimulus duration: it is 3.5 dB at the duration over 6.5 msec. The threshold of detection of transition process drops with the rise of intensity from 10 to 40 dB, remaining constant afterwards.
