Rollover measurements with Auditec NU-6 word lists.
Auditec cassette tape recordings of NU-6 word lists were used to obtain performance-intensity functions for phonetically balanced words (PI-PB) from 25 subjects with normal hearing, 19 subjects with presumed cochlear disorders, and 9 subjects with confirmed retrocochlear lesions. A rollover index greater than .35 differentiated retrocochlear hearing loss from cochlear hearing loss, although some retrocochlear subjects scored well below that level. Factors that may contribute to differences among PI-PB studies are discussed.
