Loudness perception is altered by auditory history. A continuously decreasing sound is perceived as softer than a steady sound, a phenomenon termed decruitment, likely caused by sensory adaptation.

Area of Science:

  • Auditory perception
  • Psychoacoustics
  • Sensory adaptation

Background:

  • A sound's perceived loudness depends on its auditory history.
  • A continuously decreasing tone is perceived as softer than a tone presented after silence, a phenomenon observed by Canévet (1986).
  • This effect, termed decruitment, is most pronounced at low sound levels.

Purpose of the Study:

  • To investigate the underlying mechanisms of decruitment.
  • To examine the roles of judgmental biases and sensory adaptation in rapid loudness decline.

Main Methods:

  • Magnitude estimation was used to quantify loudness judgments.
  • Experiment 1: Continuous decrease in tone level over 180s.
  • Experiment 2: Interrupted tone presentation and tone bursts at discrete levels.

Related Experiment Videos

Main Results:

  • Decruitment occurred even with only two loudness judgments (start and end of decrease).
  • Interrupting the decreasing tone significantly diminished decruitment.
  • Presenting tone bursts at successively lower levels, instead of a continuous decrease, did not produce decruitment.

Conclusions:

  • Decruitment is not due to successive judgmental biases.
  • The findings suggest that sensory adaptation is the primary cause of decruitment.
  • Continuous auditory stimulation at decreasing levels leads to a reduced perception of loudness.
