Auditec Auditory Test Ipsilateral Competing Message

The Synthetic Sentence Identification-Ipsilateral Competing Message© (SSI-ICM) can be used to test speech intelligibility or test central auditory function. It is considered appropriate for ages 11 and up. The primary signal consists of ten synthetic sentences. The competition is a male talker reading a passage.

This ipsilateral competition version has sentences and competition recorded on one track (channel) at various signal-to-noise ratios (S/N). The message-to-competition (MCR) is mixed at -20, -10, 0, +10, -20, -10, 0, +10, 0, & 0 dB per set of 10. It is considered a monaural low-redundancy test (monaural separation closure-MSC) sensitive to low brainstem lesions. It is an auditory figure ground test.
