Presentation transcript:

On the Cutting Edge of Hearing Aid Research The goal is to create a model that can seamlessly model and compare different transducers in a hearing aid system to expedite the design process. Using COMSOL Multiphysics, engineers coupled a “black box” circuitry model of a receiver with the vibroacoustic model to simulate feedback and acoustic pressure loads. COMSOL News 2017: Brenno Varanda, Knowles Corporation, USA. Simulated displacement results of the receiver and silicone tube attachment in a hearing aid (taken at 3 kHz)
