The real-ear-to-coupler difference (RECD) is the difference between the coupler response and the real ear response. This guide will provide an introduction to RECD testing. Table of contents Why does hearing aid verification matter? When to perform RECDs? How do the different RECD transducers available compare? Performing an RECD using the SPL60 probe Performing an RECD on a pediatric patient ...

Why is Real Ear-to-Coupler Difference (RECD) important in adult hearing aid fittings? Learn this & get answers to other top questions in this expert Q&A.
The clinical protocol for measuring the RECD uses an insert earphone to deliver the sig-nal and compares the SPL generated in the real ear with the SPL generated in the HA2 2cc coupler. The difference, in decibels, between the two measure-ments is the RECD.
Learn about the new ANSI standard for Real Ear to Coupler Difference (RECD) and how it affects hearing aid fitting. The webinar covers the definition, measurement, and correction of RECD with foamtips and earmolds.
Average age-specific RECD values are used in the gain prescription in Genie, the Oticon fitting software. Measuring and taking into account individual RECD is only applicable for a closed vent fitting, which is mostly relevant for either young children or in cases of a severe-to-profound hearing loss.
Understanding the RECD and how it is used in hearing aid fitting software allows clinicians to better define fitting protocols for individual listeners.
Learn how to perform Real Ear to Coupler Difference (RECD) measurements with MedRx REM or ARC systems. RECD is a method to simulate real ear measurements by coupler measurements and is useful for fitting hearing aids.
This video offers a few tips for RECD measurements, including probe microphone insertion, results management, and more. Watch the video here.
Integrating the RECD into the fitting process The RECD can be integrated into several stages of the hearing instrument fitting process as shown in Figure 3. The first stage involves audiometric assessment when data have been collected using an insert earphone.
