Mean real-ear aided response (REAR) as a function of frequency for each selection model and the National Acoustic Laboratories–Non-Linear 2 (NAL-NL2) condition using a 65-dB SPL male speech input. Real-ear unaided response (REUR) was obtained using the same speech signal. Mean NAL-NL2 targets averaged across participants are plotted as asterisk symbols. Audiogram = select-by-audiogram; Self Test = select-by-self-test; Try= select-by-trying; Questionnaire = select-by-questionnaire; Random = select-by-random-assignment; NAL2 = the custom-programmed NAL-NL2 condition; Target = NAL-NL2 prescriptive target.
