Reducing Hearing Aid Delay for Optimal Sound Quality: A New Paradigm in Processing

Sound quality in digital hearing aids is often compromised due to signal-processing delay and the resulting “comb-filter effect.” To change this, Widex recently introduced a new solution, designed particularly for mild-to-moderate hearing losses, which employs an ultralow delay. This results in a sound quality that has, until now, been unattainable in digital hearing aids. This article describes the physics of hearing aid delay, and presents a field study on the sound quality experience of the new system.
