PURPOSE: The goal of this study was to assess the functional utility of transient noise reduction (TNR) algorithms available in hearing aids via speech intelligibility and user preferences. METHOD: Two pairs of hearing aids, one pair each from Siemens and Unitron, were programmed for 17 hearing-impaired individuals after a hearing evaluation. Intelligibility was measured for each participant for sentences presented in quiet, with two types of transient noise, multi-talker babble, and in combination with one each transient noise-type and multi-talker babble. Each condition was tested with TNR-activated and TNR-deactivated in a counterbalanced, single-blinded format. Subjective ratings of overall speech understanding, comfort and sound quality were obtained for each condition. RESULTS: A significant improvement in speech intelligibility was measured with the TNR activated when speech was presented in multi-talker babble, in the presence of chair-clang transient noises, and when combining these noises. Activation of the TNR algorithm did not result in significant improvements for any of the subjective ratings. CONCLUSIONS: While improvements were limited to certain conditions, specifically those with the chair clang transient and/or multi-talker babble, TNR appears to offer an incremental step in improving the listening experience for hearing-aid users. |
