Masking patterns reveal the ear’s internal psychological representation of a sound.

Evidence

By fixing the noise masker and measuring the threshold of a tonal signal with a variable frequency, Egan and Hake were able to measure the amount of masking produced by that fixed stimulus as a function of signal frequency. We can consider the masking pattern as a psychological representation of an acoustic stimulus. In some ways, the masking pattern provides a picture of the internal psychological representation of the masker. — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 465

We can consider the masking pattern as a psychological representation of an acoustic stimulus. In some ways, the masking pattern provides a picture of the internal psychological representation of the masker. Egan and Hake measured these masking patterns for this narrowband noise presented at three different levels: 40, 60, and 80 dB SPL in order to determine if the internal representation of sound was altered by the presentation level. — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 465

Categorization

  • DEFINE: Defines the ‘masking pattern’ concept as a psychological representation of an acoustic stimulus — a core model the reader explicitly wants.
  • XREF: Relates to the reader’s goal of understanding normal vs impaired hearing because masking patterns are measured differently (wider) in impaired ears — an internal-representation tool. — connects to: Masking experiments infer auditory representation from masker effects on signals. — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 441; The physical structure of the ear itself shapes and constructs perceived sound — George Michelsen Foy, Zero Decibels: The Quest for Absolute…, 561; Auditory filters are analyzed one component at a time to build up complex effects (+8 more)
