Abstract:

The variations in the real-ear sensitivity of a circumaural earphone due to individual differences in the acoustical impedance of the ear were determined. The results indicated that between-subject variances were significant in the one-third octave bands between 800 and 2500 cs. At higher frequencies the experimental error of the measurements increased so that between-subject variances, although larger than the mid-frequency values, were not statistically significant.
