Characterization of the Dominant Structural Vibration of Hearing Aid Receivers

Abstract: Results are presented of an analysis and characterization of the mechanical vibration of hearing aid receivers, a key electroacoustic component of hearing aids. The function of a receiver in a hearing aid is to provide an amplified sound signal into the ear canal. Unfortunately, as the receiver produces sound, it also undergoes vibration which can be transmitted through the hearing aid package to the microphones, resulting in undesirable feedback oscillations. To better understand and control this important so… Show more

“…To model the internal movements of the receiver components, we separate the dynamic components, i.e. intentionally moving, from the ideally static components [2]. The translational mechanical behavior of the receiver is thus modelled through five rigid masses, connected by springs and dampers, cf.…”

“…Previous academic work addressing structural vibrations of the receiver is limited. The work includes two works by Friis [1] and Varanda [2], respectively. Varanda [2] addresses the rigid body dynamics of the receiver using Newtonian mechanics in the Lagrange-Hamilton formalism and experimental measurements.…”
