Two psychophysical methods, a method of adjustment (MOA) and a forced-choice double-staircase adaptive procedure (FCDS) (Jesteadt, 1980), were used to measure the predominant pitch and loudness of tinnitus for 11 subjects during one test session. The FCDS within-session variability of matches to tinnitus pitch was smaller than for the MOA and comparable to the within-session variability obtained when the FCDS procedure was used to match objective stimuli that approximated the frequency and level of the tinnitus. The within-session variability of matches to tinnitus loudness was nearly identical for the FCDS and the MOA and comparable to the within-session variability obtained when the FCDS procedure was used to match objective stimuli that approximated the frequency and level of the tinnitus. For 3 subjects who participated in 20 sessions, the two psychophysical methods produced correlated measures of tinnitus that tracked each other between sessions. This suggests that tinnitus may be stable within a brief time span but fluctuant in the long run.
在一次测试过程中，使用了两种心理物理学方法，即调整法（MOA）和强制选择双阶梯自适应程序（FCDS）（杰斯泰德特，1980年），来测量11名受试者耳鸣的主要音高和响度。与耳鸣音高匹配时，FCDS在测试过程中的变异性小于MOA，并且与使用FCDS程序匹配接近耳鸣频率和强度的客观刺激时获得的测试过程中的变异性相当。对于耳鸣响度匹配，FCDS和MOA在测试过程中的变异性几乎相同，并且与使用FCDS程序匹配接近耳鸣频率和强度的客观刺激时获得的测试过程中的变异性相当。对于参加了20次测试的3名受试者，这两种心理物理学方法产生了相互关联的耳鸣测量结果，且在不同测试之间相互跟踪。这表明耳鸣在短时间内可能是稳定的，但从长远来看是波动的。
