Absence of recruitment in sensorineural loss signals retrocochlear pathology.

Evidence

Diagnostic audiology has capitalized on the different growth of loudness measured in listeners with normal hearing and those with SNHL to assess retrocochlear disorders. It is expected that listeners with SNHL have recruitment if their loss is cochlear in origin. However, if a listener with SNHL does not present with recruitment, the loss may be caused by retrocochlear pathology, like an auditory nerve tumor. Such tests are now replaced by physiological tools. — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 849
