The Future of Hearing Aid Technology

So, what changed to make them successful today? Technology advanced enough to enable their application in a usable fashion: multiband compres-sion could be implemented in a small form factor and with low noise; the directivity of directional microphones improved, and they were designed to allow switching between omnidirectional and direc-tional modes to avoid noise issues; feedback cancel-lation allowed greater gain in open-canal devices, and the acoustics were improved to increase the usable bandwidth. New technologies are developed and are suc-cessful in the marketplace when they address the unmet needs of the consumers. Recent market data indicate that 71 % of hearing aid users express over
