A Comparison of Feedback Cancellation Systems in Premier Hearing Aids

Hearing Review

This study, which replicates earlier research on feedback cancellation (FBC) systems, uses three tests to evaluate the various aspects of hearing aid performance directly affected by the FBC: AGBF, Max-REIG, and a sound quality evaluation using Multi-Stimulus Test with Hidden Reference and Anchor (MUSHRA). It finds that significant discrepancies still exist among manufacturers in terms of AGBF and Max-REIG, and there remain trade-offs when reviewing the results of max-gain and the sound quality ratings together. However, considering all potential trade-offs, the Signia FBC can be considered a best-in-class algorithm in this multifaceted benchmark analysis.
