Description

<p>　　We examined the effects of digital wireless hearing systems (DWHS) using speech-in-noise perceptions and two subjective evaluation methods: the Visual Analog Scale (VAS) and the Speech, Spatial and Qualities of Hearing Scale (SSQ). The subjects were seven hearing-impaired students (their four-frequency pure-tone average was 78.9±18.6dBHL: 52.5-107.5) in inclusive settings. The results showed that the speech-in-noise perception scores improved significantly by 10%-20% with the use of DWHS in high-noise conditions (SNR 0dB to -5dB). On the other hand, the VAS scores of hearing difficulty in classroom environments improved by 40%, suggesting that reduction in the listening effort (SSQ) to speech is an important background factor. These results suggest the effectiveness of using speech-in-noise perceptions and subjective evaluation methods for the evaluation of DWHS.</p>
