“…In several studies that used the same psychoacoustic tests as this study, the SRT in noise tended to change more sensitively than the SRD and TMD. 11,18) The auditory spectral and temporal resolution largely affected speech perception and there were strong correlations between the spectral or tempo- ral resolutions and speech perception. 19,20) However, in a study that evaluated the effects of HAs on the spectral and temporal resolutions, the HAs improved speech perception in noise without changing the auditory spectral and temporal resolutions.…”

Background and Objectives: Hearing aids (HAs) with built-in sound generators can alleviate the discomfort of tinnitus in individuals with tinnitus and impaired hearing. However, it is unknown how tinnitus-control sound (TCS) affects speech perception in HA users. Therefore, this study aimed to evaluate the effect of HA TCS on auditory spectral resolution, temporal resolution, and speech perception in individuals with tinnitus and impaired hearing. Materials and Methods: The subjects were 13 elderly listeners (62.38±8.44 years, seven males, six females) with tinnitus and impaired hearing who had been using a receiver-in-canal HA with a built-in sound generator in everyday life for more than 3 months. The following psychoacoustic measurements were performed: spectral-ripple discrimination (SRD), temporal modulation detection (TMD), and speech recognition threshold in noise. The results obtained with HA-only and HA plus TCS conditions were compared. Results: There were no significant differences in SRD and TMD between the HA-only and HA plus TCS conditions (p>0.05). However, the HA plus TCS conditions were associated with worse speech recognition than the HA-only conditions (p=0.027). Conclusions: TCS constrains speech perception in noise in individuals with tinnitus and impaired hearing, implying that the TCS introduces additional noise to existing tinnitus. Therefore, we recommend that individuals with tinnitus who use a HA with a built-in sound generator should turn off the sound generator in daily life, especially in noisy environments.

Further Beneficial Effect of Hearing Aids on Speech Recognition Performance Besides Amplification: Importance of the Restoration of Symmetric Hearing

Abstract: These results demonstrate the benefits of HAs on speech perception in noise, in addition to their amplification effect, but only when HA restores symmetric hearing.
