Vignette

A patient with near-normal low-frequency hearing has a precipitous high-frequency loss and continues to miss high-frequency consonants even after a well-verified open fitting; conventional high-frequency gain runs into feedback.

Audiogram

Test findings

Normal lows with a steep high-frequency drop; limited usable high-frequency hearing.
