Seven monaural hearing aid users and four binaural hearing aid users (10 to 50 years old) were administered a hearing evaluation with earphones. Measures recorded were pure tone average (PTA), speech reception threshold (SRT), and speech discrimination scores. These results were compared with the results of an evaluation conducted one or more years previously. A t test was applied to the mean score differences from initial test to retest of the aided ears versus the unaided ears to determine the stability of speech discrimination in the unaided ear of persons with a bilateral loss of hearing sensitivity.PTA and SRT decreased minimally from initial test to retest indicating good threshold stability. Speech discrimination mean scores decreased, with a larger decrease observed for the unaided ears than the aided ears of monaural and binaural subjects. However, the larger decrease was not statistically significant. Therefore the data indicated that an ear which is not stimulated by amplification, with a hearing loss of sensitivity of 50dB HL to 80dB HL, does not have a significant decrease of speech discrimination as compared to an aided ear with a similar loss of hearing sensitivity.
