UNLABELLED
Characteristics of how external and middle ear resonance frequency can impact the capture of otoacoustic emissions.
AIM
to study the impact of external and middle ear resonance frequency in otoacoustic emissions.
STUDY DESIGN
Prospective, clinical, series study.
MATERIALS AND METHODS
Microphone-probe measurements were made in the external ear, together with multifrequency timpanometry distortion product transient otoacoustic emissions in 19 right and 20 left ears from male individuals and 23 right and 23 left ears from female individuals with 17 to 30 years of age. The 85 ears were audiologically normal.
RESULTS
We did not observe statistically significant associations between the best otoacoustic emission best frequencies and the occluded external and middle ear resonance frequencies.
CONCLUSION
Response levels for both transient and distortion product otoacoustic emissions are not influenced by the external and middle ear resonances alone.
未加标签
研究中耳和外耳共振频率如何影响耳声发射的捕获。
目的
研究中耳和外耳共振频率对耳声发射的影响。
研究设计
前瞻性、临床、系列研究。
材料和方法
对 19 名男性和 20 名女性个体的右耳和左耳进行了麦克风探头测量，同时对 17 至 30 岁的 23 名男性和 23 名女性个体的右耳和左耳进行了多频鼓室声导抗测试和畸变产物瞬态耳声发射。85 只耳朵听力正常。
结果
我们没有观察到最佳耳声发射最佳频率与封闭的中耳和外耳共振频率之间存在统计学显著关联。
结论
瞬态和畸变产物耳声发射的反应水平不受中耳和外耳共振的单独影响。
