Custom Directional Hearing Aids: State-Of-The-Art

By Trine, Tomothy D., PhD; Hearing Professional, Vol. 54, No. 2, pp. 9-14
Publication Date: March-April 2005

Article discusses advances in the fidelity and sophistication of fitting strategies and signal processing technology utilized in state-of-the-art hearing aids. Directional processing has proven to be the only signal processing approach to yield improvements in speech recognition in noisy environments, while other obstacles associated with direction hearing aids have been solved, such as size, directional performances, cosmetic concerns, noise performance, and stability over time. The author discusses possible reasons why hearing professionals have failed to utilize the full benefits offered by directional processing technology. Several possibilities are discussed, including the reality that positive directional processing performance in noisy environments had only been proven in laboratory settings at the time the article was written.
