The incidence, amplitude and frequency spectrum of transitory otoacoustic emissions (TOAE) were analyzed in a sample of 232 normal hearing ears, after click stimulation to determine normal parameters. 116 subjects, 58 female ranging in age from 18 to 30 years, mean age 23.1 years, and 58 male were from 18 to 32 years, mean 23.7 years, were included in this study. TOAE were normal in all ears, 132 (57%) ears had TOAE at all frequencies between 0.5 and 5 kHz. The mean amplitude of TOAE was 16 dB SPL (SD 3.77) and the highest amplitude was elicited at 1-2 kHz frequency. The intensity of stimulation correlated directly with evoked response amplitude and the subject's age correlated inversely with the incidence and amplitude of TOAE.
为确定正常参数，对232只听力正常耳朵的样本进行了瞬态耳声发射（TOAE）的发生率、幅度和频谱分析，刺激声为短声。本研究纳入了116名受试者，其中58名女性，年龄在18至30岁之间，平均年龄23.1岁；58名男性，年龄在18至32岁之间，平均年龄23.7岁。所有耳朵的TOAE均正常，132只（57%）耳朵在0.5至5千赫的所有频率上都有TOAE。TOAE的平均幅度为16分贝声压级（标准差3.77），最高幅度出现在1至2千赫频率。刺激强度与诱发反应幅度直接相关，受试者年龄与TOAE的发生率和幅度呈负相关。
