Varibel Hearing-Aid Glasses Integrate Eight Directional Microphones
By Hearing Mojo,Publication Date: April 2006
Article provides a review of Varibel Hearing-Aid Glasses, which are designed to hide hearing aids in a pair of glasses. The Varibel Hearing-Aid Glasses integrate eight sophisticated directional microphone into the frame of a pair of glasses. The design doubles the boost in hearing traditionally yielded by directional microphones in standard aids. There are two ways that digital hearing aids can help people to hear speech in noise: (1) directional microphones integrated into the hearing aid, and (2) alogrithms within the hearing aid’s digital signal process that suppress background noise while boosting frequencies in the normal hearing range. Research is discussed that demonstrates the importance of directional Varibel Glasses and recharger microphones in terms of enhancing speech in noisy environments such as restaurants or cocktail parties. By placing more microphones closer to the speaker, Varibel Hearing-Aid Glasses boost hearing frequencies by 8.2 decibels, which is more than twice the amplification yielded by standard hearing aids with directional microphones. The glasses were created by researchers at the Delft University of Technology in the Netherlands.
