基于颞骨标本的振动声桥耦合器机械性能比较，发现正向耦合（如 cliP、stapes head）在125-8000Hz频段较反向耦合（圆窗、脂肪垫）具有7-25dB的声学增益优势，尤其2000Hz以下差异显著。研究采用激光多普勒测速技术校正反向耦合的耳蜗内压损失，建立标准化比较参数。

浮动质量换能器（FMT）在正向（短过程，SP）和反向（圆窗，RW）刺激模式下的声学传输效率及耦合配置优化研究。采用激光多普勒振动仪（LDV）和内耳压力差（ICPD）联合测量方法，对比SP-Coupler、RW-Coupler及RW-Precision-Coupler在200 Hz-8 kHz频段的输出特性。结果显示LDV ...
