目的：本研究的目的是通过临床和现实环境中语音识别的客观和主观测量，比较3种类型的远程麦克风助听技术（HAT），自适应数字宽带，自适应频率调制（FM）和固定FM的好处。方法：参与者包括11名成年人，年龄在16至78岁之间，主要患有中度至重度双侧听力损伤（HI），他们佩戴双耳耳后式助听器;以及15名听力正常的成年人，年龄在18到30岁之间。句子识别在安静和噪声和主观评级中获得3个条件的无线信号processing.Results：性能的听众HI时，使用自适应数字技术是显着优于FM技术，在最高的噪声水平的最大好处。大多数听众在现实世界的嘈杂环境中收听时也更喜欢数字技术。无线技术允许HI的人超过正常听力的人在语音识别噪声中，最大的好处发生与自适应数字technology.Conclusion：使用自适应数字技术相结合的speechreading线索将允许HI的人从事通信的环境中，否则不可能与传统的无线技术。
Purpose: The purpose of this study was to compare the benefits of 3 types of remote microphone hearing assistance technology (HAT), adaptive digital broadband, adaptive frequency modulation (FM), and fixed FM, through objective and subjective measures of speech recognition in clinical and real-world settings.Method: Participants included 11 adults, ages 16 to 78 years, with primarily moderate-to-severe bilateral hearing impairment (HI), who wore binaural behind-the-ear hearing aids; and 15 adults, ages 18 to 30 years, with normal hearing. Sentence recognition in quiet and in noise and subjective ratings were obtained in 3 conditions of wireless signal processing.Results: Performance by the listeners with HI when using the adaptive digital technology was significantly better than that obtained with the FM technology, with the greatest benefits at the highest noise levels. The majority of listeners also preferred the digital technology when listening in a real-world noisy environment. The wireless technology allowed persons with HI to surpass persons with normal hearing in speech recognition in noise, with the greatest benefit occurring with adaptive digital technology.Conclusion: The use of adaptive digital technology combined with speechreading cues would allow persons with HI to engage in communication in environments that would have otherwise not been possible with traditional wireless technology.
