Comparison of Speech Audiometry Stimulus Lists on Hearing Impaired and Normal Hearing Subjects

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.
