The influence of audiometric configuration on pure-tone, warble-tone and narrow-band noise thresholds of adults with sensorineural hearing losses.

Thresholds measurements for pure tones, warble tones, and narrow-band noise were compared for adult sensorineural hearing-impaired subjects with gradual and sharp audiometric configurations. Results demonstrated that audiometric configuration does not significantly affect the relationship between pure tones and warble tones but does affect the relationship between pure tones and narrow-band noise. Differences were most apparent at the higher frequencies. Clinical implications are discussed.
