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.
