Dichotic Sentence Identification

The Dichotic Sentence Identification (DSI) test is a dichotic test for binaural separation for ages 11 and up using verbal stimuli. It was developed to conceive a dichotic listening task that would be only minimally affected by peripheral hearing loss. Sentences selected from the Synthetic Sentence Identification (SSI) test are presented dichotically. Onsets and offsets of the sentences are aligned with an accuracy of 100 microseconds.

The DSI is a viable test of central auditory function in the hearing impaired population. The test is applicable for use in auditory assessment of impaired ears through pure tone averages (PTAs) up to 50 dB at least. The DSI is made up of two sets of 30 pairs of sentences.

The Dichotic Sentence Identification includes a) audio recording, b) instructions and score forms as printable pdf files. The three-page instructions encompass method, scoring, and interpretation. Normative data is included for adults only. It would be reasonable to expect children over the age of eleven to test as well (or nearly as well) as adults. Available from Auditec, IncCall 1-800-669-9065 (from US) or 314-416-1050 (outside the US) to order.
