为探讨人工中耳的听觉,特别是在噪声环境下的语音清晰度。作者对10例人工中耳植入术患者与配戴助听器者进行了比较研究。认为人工中耳与助听器的语音清晰度,在非噪声下没有差异,而在噪声环境下,人工中耳比助听器的语音清晰度好。不加噪声时人工中耳组与助听器组的语音清晰度,分别是96.8±3.6%和94.8±4.1%;而加65dBSPL噪声时,人工中耳有1例低下为66%,其平均值是81.6±9.1%,而助听器组的平均值是66.8±10.6%,两者的语音清晰度有显著差异(P<0.001)。对
In order to explore the artificial middle ear hearing, especially in the noisy environment of speech intelligibility. The authors compared 10 patients with artificial middle ear implants and those wearing hearing aids. The speech intelligibility of the artificial middle ear and the hearing aid is considered to be no different under no noise, while in the noisy environment, the artificial middle ear has better speech intelligibility than the hearing aid. The speech intelligibility of the artificial middle ear group and the hearing aid group without noise was 96.8 ± 3.6% and 94.8 ± 4.1%, respectively; while with 65 dB SPL noise, 1 case of the artificial middle ear was 66% lower with an average of 81.6 ± 9.1%, while the average hearing aid group was 66.8 ± 10.6%, with significant differences in speech intelligibility (P <0.001).
