Summary
High-frequency audiometry can reliably monitor hearing in patients taking ototoxic medications. This study found no significant differences in hearing threshold measurements between sound suites and hospital rooms, establishing bedside testing validity.
Area of Science:
- Audiology
- Ototoxicity Monitoring
- Hearing Science
Background:
- High-frequency audiometry is crucial for monitoring hearing sensitivity in patients receiving ototoxic medications.
- Sound suite measurements are considered reliable, but bedside evaluations are often necessary.
Purpose of the Study:
- To compare high-frequency hearing thresholds measured in a sound suite versus a hospital room.
- To assess the test-retest reliability of high-frequency thresholds obtained in a hospital room setting.
Main Methods:
- Twenty-five normal-hearing subjects participated in the study.
- High-frequency hearing thresholds were measured in both a sound suite and a hospital room.
- Test-retest reliability was evaluated for measurements taken in the hospital room.
Main Results:
- No significant differences were found between high-frequency thresholds measured in a sound suite and a hospital room.
- Test-retest differences in the hospital room were not significant.
- The majority of test-retest differences were within +/- 10 dB across all tested frequencies.
Conclusions:
- High-frequency audiometry can be reliably performed in a hospital room setting.
- Bedside high-frequency hearing assessments are a viable alternative to sound suite measurements.
- This finding supports the use of bedside audiometry for ototoxic medication monitoring.
