Abstract
The performances for the detection of intensity increment were measured for pures tones at different frequencies and different levels. It is known that no correlation between loudness adaptation and the detection of intensity increment has been found. Our experiments consist in measuring the detection of an increment (using d') as a function of the delay between the onset of a pulsed pedestal and the onset of a 50 ms increment. For high frequencies and high levels, d' increases with the delay. This phenomenon could be the consequence of a neural adaptation.
