Recent advancement in hearing aid technology boosted the performances of digital hearing aids. The hearing aid wearers also had higher expectation on hearing assistive devices than before. Thus, more elaboration was needed on objective evaluation, selection, and fitting for the potential benefits of hearing aids. From this context, real ear measurement (REM) became important for accurate measurement of resonances in ear canal since these resonance properties were characteristic and habituated for individuals. Potential hearing aid wearers would feel comfortable and natural with the amplified sounds from fittings based on REM. In this article, exemplary cases of effective hearing aid fittings were reviewed with the application of real rear measurement.
