Summary

Wind-noise is highly disturbing to hearing impaired individuals wearing hearing aids who wish to participate in outdoor conversations where wind is present or during activities such as walking or running. In these situations, wind noise significantly reduces signal-to-noise ratio and, consequently, the intelligibility of speech and sounds may be significantly impaired. This negative effect is exacerbated with the use of directional microphone schemes in the hearing iads. The objective of this project is to determine the efficacy of the MH Acoustics' multi-microphone wind-noise reduction invention for the digital hearing aids market. MH Acoustics' wind noise reduction technology is unique since it provides instantaneous convergence while maintaining directionality of the microphone array. Current commercial technologies do not provide this feature. We are hypothesizing that, due to the design of the algorithm, speech perception ability and sound quality perception will be better than that available with traditional directional and/or omnidirectional microphone schemes in windy environments.
