Comparison of performance across three directional hearing aids.

摘要: This study compared the speech recognition performance of 12 hearing-impaired listeners fit with three commercially available behind-the-ear hearing aids in both directional and omnidirectional modes. One digitally programmable analog two "true digital" were selected as test instruments. Testing was completed "living room" anechoic room environments. Speech examined using modified forms Hearing Noise Test Nonsense Syllable Test. The single competing stimuli these tests replaced five uncorrelated sources. Results revealed a significant noise advantage for all comparison to their counterparts. Maximum did not significantly vary across circuit type, suggesting that processing differences affect maximum aid performance. In addition, results suggest one reverberant environment cannot be used accurately predict an differing reverberation.
