Abstract

The appropriateness and differences of different speech recognition and speech intelligibility word lists were investigated. It has been reported that the use of two-syllable spondee words that are comprised of high frequency sounds may more accurately represent the true speech recognition abilities of those individuals with a high frequency sesorinueral hearing loss. There is also some question whether the use of 40 dB SL (re: SRT) for speech intelligibility testing may well undershoot the PB-Max of an individual with a high frequency sloping sensorinueral hearing loss (Martin and Jansen, 1985). Fifteen individuals with a pre-determined high frequency, sloping sensoriunueral hearing loss and ten with normal hearing were adminstered speech recognition threshold tests using the C.I.D. W-1 and the Martin-Jansen High Frequency word lists. These subjects were administered the C.I.D. W-22, NU-6, and an open set presentation of the California Consonant Test at 20, 30, 40, and 50 dB SL (re:SRT of W-1 and Martin-Jansen High Frequency word lists). Results indicated that there is a significant difference between the SRT of the C.I.D. W-1 and the Martin-Jansen High Frequency Word List for the hearing impaired group, but not for the normal hearing group. Results indicated that the use of 40 dB SL (re: SRT) does indeed undershoot an individuals maximum speech intelligibility ability for the hearing impaired group. Statistical analysis showed that there was a significant difference between lists at 20, 30, and 40 dB SL, and 50 dB SL for the hearing impaired group.
