Real-Ear-to-Coupler Difference (RECD) accounts for the difference in decibels as a function of frequency between sound pressure level (SPL) at a specified measurement point in the ear canal relative to the SPL measured in a 2cc coupler for a specified input signal. Put less formally the RECD equals the difference (in dB) across frequencies, between the SPL measured in the real-ear and in a 2cc coupler, produced by a transducer generating the same input signal (Pumford & Sinclair 2001).
