可植入中耳腔壓力麥克風之可行性分析

// Feasibility analysis of an implantable middle ear cavity pressure microphone

本研究評估完全植入式人工耳蝸（TICI）中耳腔麥克風（MECM）設計｜透過模型與人體屍耳音響測試發現，中耳隔離可提升聲壓效能｜具5毫米MEMS微機電系統的MECM在密封中耳後，符合TICI需求，顯示其為具潛力的植入式麥克風方案。

// This study evaluates a middle ear cavity microphone (MECM) design for totally implantable cochlear implants (TICI). Using a model and sound measurements in human cadaver ears, the research found that acoustically isolating the middle ear improves sound pressure performance. A 5 mm MEMS-based MECM with optimized housing can meet TICI requirements if the middle ear is sealed from the mastoid cavity. The results suggest the MECM is a promising implantable microphone concept for TICIs.
