| 摘 要： | 骨导振子佩戴位置会影响骨传导声重放的性能,但已有研究还不够全面和完善。针对11名双耳听力正常的受试者,采取不同的骨导振子佩戴位置,对骨传导声重放在听力阈值、主观音质评价和语言清晰度3个方面进行了研究。实验结果表明不同的佩戴位置会影响骨传导声重放性能,髁骨位置在3个实验都表现最好,髁骨的听力阈值比乳突位置平均低8.7 dB,主观音质评价得分平均高乳突38.4分。该文的研究可为骨导振子佩戴位置的选择提供依据,并为声重放质量的改进提供参考。

| Abstract: | The bone conduction(BC)vibrator placing positions have an effect on BC sound reproduction performance,but the existing research is not comprehensive and sufficient.Three experiments of hearing threshold,subjective sound quality evaluation,and speech intelligibility were performed in the listening room when the 11 normal hearing listeners place BC vibrator on different positions of head.The results showed that the factor of position affected the performance of BC sound reproduction,the condyle position performed best in all experiments.The average hearing threshold of condyle was 8.7 dB lower than mastoid,and the score of subjective sound quality evaluation was 38.4 points higher than mastoid.The result of this paper provides a scientific basis for the design of BC headphones and a reference for the improvement of sound reproduction quality. |
