Abstract
Repeated tinnitus loudness matches (LMs) were obtained to determine response reliability
using a computer-automated technique with two procedural variations, fixed or random
step sizes, to increase output level during the initial ascending series of tones
at each frequency. Twenty subjects with stable, tonal tinnitus were evaluated with
both methods during each of two sessions. Response instructions were displayed on
a portable computer, and a pen device was used to make response choices that appeared
on the touch-sensitive video monitor. For each method, hearing thresholds and LMs
were obtained, with 1-dB resolution, at 1/3-octave frequencies from 1 to 16 kHz. Analyses revealed reliability of LMs to be equivalent
between methods. LM data are reported in both dB SPL and dB SL, with the SPL values
providing greater reliability both within and between sessions (all r's ≥ .889, p's
≤ .0001).
