UNLABELLED
Otoacoustic Emissions are generated by the cochlea in response to sound stimuli. They can be generated by clicks or specific frequency stimuli, such as tone pips. This is a quick and objective test with several applications.
OBJECTIVE
To investigate the influence of the type of stimulus achieving otoacoustic emissions in individuals with mild and moderate sensorineural hearing loss of sloping configuration.
MATERIAL AND METHOD
Thirty-two male and female patients aged from 17 to 63 years, with symmetric sensorineural hearing loss with a sloping configuration were evaluated. All subjects underwent transient otoacoustic emissions testing elicited by clicks and 2.000 Hz and 4.000 Hz tone pips.
RESULTS
The degree of hearing loss and gender influenced otoacoustic emissions; it was significant for click stimulus and tone pips at 2.000 Hz. Emissions were absent more often in females with both procedures.
CONCLUSIONS
Otoacoustic emissions evoked with clicks coincided with the emissions of tone pips at 2.000 Hz. Tone pips at 4.000 Hz were more sensitive than clicks for detecting impairment in individuals with high frequencies hearing loss. Gender and the degree of hearing loss ere factors that affected OAE registration.
未加标签
耳声发射是耳蜗对声音刺激的反应产生的。它们可以由 click 或特定频率的刺激（如 tone pip）产生。这是一种快速且客观的测试，有多种应用。
目的
研究在具有缓降型感音神经性听力损失的个体中，不同刺激类型对耳声发射的影响。
材料和方法
对 32 名年龄在 17 至 63 岁之间的男性和女性患者进行评估，这些患者均具有对称的缓降型感音神经性听力损失。所有受试者均接受了瞬态耳声发射测试，刺激方式为 click 和 2.000 Hz、4.000 Hz 的 tone pip。
结果
听力损失程度和性别影响耳声发射；click 刺激和 2.000 Hz 的 tone pip 均有显著影响。两种测试中，女性的耳声发射缺失更为常见。
结论
click 诱发的耳声发射与 2.000 Hz 的 tone pip 诱发的耳声发射一致。4.000 Hz 的 tone pip 比 click 更敏感，可检测高频听力损失个体的听力障碍。性别和听力损失程度是影响 OAE 记录的因素。
