Prescriptive approaches are typically implemented for estimating the optimal gain and output during an initial hearing aid fitting. In this study, simulated real ear aided responses (REAR) were compared for hearing aids from different manufacturers and compared to targets for different prescriptive methods. The findings from the present study indicated that for the same generic prescriptive method and the same degree of hearing loss, the targets varied up to 26 dB between hearing aid manufacturers and the real-ear analyzer, when all parameters were held constant.
