HEARING DIAGNOSTICS
SISI TEST
Advanced hearing assessment that measures the ability to detect small changes in sound intensity, helping identify cochlear (inner ear) hearing loss.
What is an SISI Test?
Short Increment Sensitivity Index (SISI) Test is a specialized hearing assessment used to evaluate the inner ear’s ability to detect very small changes in sound intensity. It helps identify cochlear (inner ear) hearing loss and distinguish it from other types of hearing disorders.
WHY SISI TESTING IS IMPORTANT
Identifies Cochlear Hearing Loss
Helps determine whether hearing loss primarily originates from the inner ear (cochlea).
Supports Accurate Diagnosis
Assists audiologists in differentiating cochlear hearing loss from other auditory conditions.
Aids Treatment Planning
Provides valuable information for hearing aid fitting and hearing rehabilitation.
Enhances Diagnostic Accuracy
Works alongside other hearing tests to provide a comprehensive hearing evaluation.
HOW DOES THE SISI TEST WORK?
Step 1
A continuous tone is presented through headphones at a comfortable listening level.
Step 2
The sound intensity is increased by very small increments, usually 1 dB.
Step 3
The patient indicates whenever they notice a slight increase in loudness.
Step 4
The percentage of correctly detected increments is calculated to assess cochlear function.
