1. 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.
