Jack Bennett, BSc (Hons), International Clinical Trainer from the Interacoustics Academy discuses some alternative methods a clinician can use to verify a hearing aid fitting, when in situ real ear measurements aren’t appropriate or have been rendered inaccurate by various factors. He also discusses the changing landscape of hearing aid fitting in light of recent technological advancements, such as hearing aids with remote fitting apps. Jack Bennett explains how to ensure Real Ear to Coupler Difference (RECD) measurements can be performed to the highest quality, focussing on different techniques and the limiting factors. There is also a guide to using the SPL60 probe for RECDs. This is the second video in a three part series on remote aid fitting.
