Background and Objectives The purpose of this study was to figure out the clinical effectivenessof the bluetooth wireless streaming when used with a hearing aid during cell phoneconversation for hearing-impaired listeners. Subjects and Method Twenty-four adults with hearing loss participated (mild: 3, moderate:13, moderately severe: 8) in the study. The following three objective tests and one subjectivequestionnaire were administered to all participants; 1) consonant and Monosyllabic test in annoisy environment, 2) speech recognition test in quiet and noisy conditions, 3) listening efforttest, and 4) questionnaire about sound quality and preference. Each objective test was conductedin three different cell phone conversation environments as follows; 1) unaided condition,2) aided condition, with the bluetooth function off, and 3) aided condition, with the bluetoothfunction on. Results In the aided condition with the bluetooth function off, performance on consonant andmonosyllabic tests was the lowest (p＜0.05). However, when the bluetooth function was turnedon, the result showed statistically significant superior performance (p＜0.05). For the words andsentences test in noisy conditions, using wireless streaming feature with the hearing aids werebeneficial compared to not using the feature (p＜0.05). However, no significant difference wasfound between the bluetooth off and on conditions in quiet conditions. Listening effort wassignificantly lower in noisy background for aided bluetooth on condition (p＜0.05). There wasno significant difference in sound quality according to each condition, but the preference ofBluetooth feature was overwhelmingly high. Conclusion Bluetooth wireless streaming is beneficial during phone conversation in noisyenvironments for users of hearing aids.
