SISI Test
SISI is designed to test the ability to recognise 1 dB increase in intensity during a series of bursts of pure
tones presented 20 dB above the pure tone threshold for the test frequency. It can be used to differentiate
between cochlear and retrocochlear disorders as a patient with a cochlear disorder will be able to
perceive the increments of 1 dB, as where a patient with a retrocochlear disorder will not.
