Test-retest reliability of high-frequency thresholds at bedside with sensorineural hearing-impaired listeners.

Previous investigations have established the reliability of high-frequency thresholds performed in a sound suite using headphones. In addition, test-retest reliability of high-frequency thresholds in adults with normal hearing in a hospital room versus a sound-treated booth has also been established. The current study evaluated the test-retest reliability of thresholds in the 8000- to 18000-Hz range in 15 hearing-impaired adults (26 ears) with varying degrees of sensorineural hearing loss. A high-frequency audiometer and supra-aural earphones were used to measure thresholds in a typical hospital room. Results revealed no significant difference between repeated threshold measures. This study represents the third phase of an ongoing project to develop reliable bedside monitoring of patients undergoing ototoxic medical treatment.
