What effect does mechanical stress have on hearing aids?

Mechanical stress refers to the physical strain or pressure applied to hearing aids, which can negatively impact their performance. When hearing aids are subjected to mechanical stress, it can lead to changes in the components of the device, such as the microphone, speaker, or circuit board. These changes can cause harmonic distortion, which is an alteration in the sound quality that results in the introduction of unwanted frequencies or harmonics. Distortion affects how clear and natural the sound produced by the hearing aid is perceived by the wearer, potentially making it more difficult to understand speech or enjoy music.

This phenomenon underscores the importance of ensuring hearing aids are well-designed to withstand everyday use while maintaining sound fidelity. Understanding the effects of mechanical stress can help dispensers advise users on proper care and handling of their devices to minimize potential issues.
