What is the acceptable range of test/retest reliability for threshold measurements?

The acceptable range of test/retest reliability for threshold measurements in audiology is typically around ±5 dB. This range signifies that when a patient's threshold is tested on different occasions, it is expected that there will be minor variations due to factors such as external noise, the patient's condition at the time of testing, and the sensitivity of the measuring equipment. A ±5 dB range is considered clinically acceptable and aligns with standard practices in audiometric testing.

Maintaining a test/retest reliability within this range ensures that the results are consistent and trustworthy, which is crucial for accurate diagnosis and treatment planning for hearing loss. Variations beyond this range may indicate issues with either the testing procedure or the patient's auditory response, warranting further investigation.
