Summary

Sound quality perception, or ripple-density resolution, remains stable across sound levels for normal hearing listeners. Maskers slightly affect resolution, with off-frequency maskers showing level-dependent decreases at higher intensities.

Area of Science:

  • Auditory perception
  • Psychoacoustics
  • Signal processing in hearing

Background:

  • Understanding auditory perception of complex sound spectra is crucial.
  • Ripple-density resolution describes the ability to discern fine spectral details.
  • Listener's ability to resolve spectral details under varying sound conditions is not fully understood.

Purpose of the Study:

  • To investigate how sound level affects ripple-density resolution.
  • To examine the influence of different masker types (on-frequency and off-frequency) on spectral resolution.
  • To determine the impact of masker characteristics on the perception of sound spectra.

Main Methods:

  • Psychoacoustic experiments were conducted on normal-hearing listeners.
  • Ripple-density resolution was measured using a phase-reversal detection task.

  • Probe bands (0.5 oct wide) at 1, 2, and 4 kHz were tested with and without maskers at various sound levels (40-90 dB SPL).

    • Main Results:

    • In the absence of a masker, ripple-density resolution was largely independent of sound level (40-90 dB SPL).
    • An on-frequency masker slightly reduced resolution but maintained level independence.
    • An off-frequency low-side masker caused a slight decrease in resolution, showing level independence at lower levels (40-60 dB SPL) and a progressive decrease at higher levels (70-90 dB SPL).

    Conclusions:

    • Sound level has a limited impact on spectral ripple-density resolution in normal hearing, especially without maskers.
    • Off-frequency maskers, particularly at higher sound levels, can degrade spectral resolution in a level-dependent manner.
    • These findings contribute to understanding the robustness and limitations of auditory spectral analysis.
