We envision future hearing aid systems, where wireless microphones, which are potentially equipped with local signal processing capabilities, are distributed in the space around the hearing aid user. The goal of this acoustic sensor network is to capture sound sources of interest and present them to the hearing aid user, while suppressing any interferers. To enable this future hearing aid system, the project investigates methods to determine i) where the acoustic sensors are located w.r.t. the hearing aid user, ii) where sound sources are located with respect to the hearing aid user, and iii) whether these sound sources are of potential interest to the hearing aid user (e.g., if they are speech, audio, or noise).
