The audiogram measures only sound detection, not other auditory perceptions

Evidence

The audiogram is an historical assessment tool, developed in the early 1900s, originally used because we had limited knowledge of the ear, and we did not have access to technology that could easily generate and manipulate complex sounds in real time for audiological assessment. The recent century has repeatedly demonstrated that the audiogram does not reflect our multiple auditory perceptual abilities. The audiogram is critically important for addressing site of lesion (whether a hearing loss is conductive, in the outer or middle ear, or sensorineural) and is also widely used to guide hearing aid fitting. However, this text will illustrate that the variability in perceptual deficits experienced by listeners with sensorineural hearing loss is quite high and that the audiogram does not provide a measurement of any other level of auditory perception besides detection. — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 36

  • QUESTION: Worth chasing: what specific perceptual deficits vary most widely among listeners with matching audiograms?
  • XREF: Links with the general critique that single summary metrics (like the book’s other assessment tools) flatten multidimensional phenomena.
