The audiogram fails as a robust indicator of perceptual deafness deficits

Evidence

In many cases, we observed that sensorineural hearing loss leads to deficits in psychoacoustic abilities and that the degree of these deficits can vary considerably for listeners with hearing loss. We also observed that these abilities encompass much more than the audiogram; in fact, in many cases the audiogram does not provide a robust indicator of the degree of deficits experienced by an individual listener. — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 1676

• XREF: Connects with the broader theme that clinical standard measures miss real perceptual variation—parallels other domains where diagnostic surrogates diverge from lived experience.
