TDT (Tone Decay Test)

The Tone Decay Test is used to evaluate the function of the auditory nerve by measuring how long a sound can be heard at a constant level. If the sound fades quickly, it may indicate a problem with the auditory nerve.

This test is particularly useful in detecting retrocochlear disorders, which affect the nerve pathways beyond the inner ear. It provides important diagnostic information that cannot be obtained through basic hearing tests. Our audiologists perform this test with precision to ensure accurate results. TDT helps in identifying underlying conditions and guiding further medical evaluation if required.
