| Outline of Final Research Achievements |
This study employed a stimulus presentation method by a loudspeaker and various averaging numbers to record clear speech auditory brainstem responses (speech ABR). The goal was to clarify the relationship between listeners’ consonant discrimination scores and speech ABR characteristics for an objective hearing aid fitting. As a result, the speech ABR obtained with a loudspeaker were almost similar to the waveforms obtained with an inserted earphone in time and frequency domains. The averaging number of 4000 times was suitable for recording clear speech ABRs. It was found that the relationship between the consonant discrimination scores and the coding pattern of the transition portion of the speech ABR showed good correlation in subjects with normal hearing. In subjects with hearing loss, however, there was no relationship between the consonant discrimination scores and the speech ABRs.
