Abstract:
Intratester test-retest reliability of insertion gain was determined on 28 subjects using the Frye 6500 real-ear analyzer. Results revealed mean differences of less than 1 dB for repeat measurements at six test frequencies between 250 and 4000 Hz. Also, over 80% of the repeat measures were within +/- 3 dB of the first measure. The results of this study are compared with previous studies of intratester reliability of insertion gain measures.
