Modeling of structural-fluidic interactions for the design of digital MEMS speakers in hearing aids

Abstract

Micro Electro-Mechanical Systems (MEMS), applied to the field of hearing aids, offer ample possibilities for improving of performance, reliability and functional specifications, and they are also promising in terms of energy saving. In this paper, some of the major design problems relating to the use of MEMS for sound waves generation inside the ear canal are analyzed.
