Background and Objectives The main objectives of this study were to determine the clinicalusefulness of the program-assisted and real ear measurement (REM)-assisted fitting ofhearing aids. Subjects and Method Fifteen participants with moderate to moderately severe hearing losswere enrolled in this study. Objective and subjective fitting results were assessed to comparethe benefits between the program-assisted fitting (using a software fitting program) and theREM-assisted fitting. Real ear insertion gain (REIG), sound-field audiometry using warble tone,and Korean Hearing in Noise Test (K-HINT) were performed as objective tests. Sound qualityrating was performed as a subjective test. Results In the program fitting, 48.89% of fitting points failed to come within ±10 dB of theREIG target. In the REM fitting, however, the percentage of failure significantly decreased to23.33% (p=0.013). In K-HINT test, the reception threshold for speech in quiet situation significantlydecreased from 50.1 dB HL with the program fitting to 44.7 dB HL after the REM fitting(p<0.001). In front noise condition, signal-to-noise ratio improved from 4.53 dB to 3.50 dBwith the REM fitting without statistical significance (p=0.099). In the sound quality rating, theREM fitting (4.27±0.56) showed a significantly better sound quality ratings than the programfitting (3.69±0.74) (p=0.017). Conclusion The REM fitting showed better results in both subjective and objective measurementsthan the program fitting
