Summary
The test-retest reliability of the auditory steady-state response (ASSR) was evaluated in normal-hearing adults. The 80-Hz multiple-ASSR system demonstrated clinically acceptable reliability for auditory threshold testing.
Area of Science:
- Audiology
- Neuroscience
- Biomedical Engineering
Background:
- Test-retest reliability of auditory steady-state response (ASSR) is not well-established.
- Assessing ASSR reliability is crucial for accurate auditory threshold determination.
Purpose of the Study:
- To evaluate the test-retest reliability of an 80-Hz multiple-ASSR system.
- To apply comprehensive statistical methods for reliability assessment in normal-hearing adults.
Main Methods:
- Twenty-nine normal-hearing adults participated in two test-retest sessions.
- Auditory steady-state response (ASSR) thresholds were determined using a descending search protocol with 10-dB precision.
- Reliability was assessed using Pearson correlation, ANOVA, and standard error of measurement (SEM).
Main Results:
- Correlations for ASSR thresholds ranged from poor (0.34 at 500 Hz) to moderate (0.55 at 1000-4000 Hz).
- ANOVA revealed no significant differences between test and retest for ASSR thresholds.
- SEM values for ASSR were within +/-10 dB HL, indicating acceptable clinical error tolerance.
Conclusions:
- The 80-Hz multiple-ASSR technique exhibits clinically acceptable test-retest reliability in normal-hearing adults.
- This finding supports the use of the multiple ASSR system for reliable auditory threshold measurements.
