Binaural signal processing algorithms for hearing aids


Within the last half-decade that it has become possible to transfer audio signals between bilaterally-fitted hearing aids (Moore, 2007, The Hearing Journal, Vol. 40, No. 11, pp 46-48). This is primarily attributed to the technological advances in integrated circuit design, longer lasting batteries and also wireless inter-communication between the two hearing aids, e.g., using near-field magnetic induction (NFMI) communication. The possibility to exchange audio signals between bilaterally-fitted aids opens the door to new types of binaural signal processing algorithms to assist hearing-impaired listeners separate sounds of interest from background noise.

Research location

Electrical and Computer Engineering

Program type



This research project explores binaural signal processing algorithms for hearing-aids. The operation of hearing aids in complex spatial sound environments will be explored. A database of spherical microphone array recordings will be created. A spherical loudspeaker array will be used to reconstruct the spatial audio and hearing aid algorithms may be tested using an acoustic manikin.
