Abstract

In order to diagnose and locate the defected site of two main sensorineural hearing loss which were cochlear hearing loss and retrocochlear hearing loss, a technique that based on AR spectrum analysis for the signals of Transient Evoked Otoacoustic Emissions (TEOAE) and TEOAE suppressed by Contralateral Acoustic Stimulation (CAS) was proposed. Firstly, normal ranges of the two curves which reflecting the information of relationship of TEOAE's logarithm AR spectrum with frequency and the relationship of the suppressed TEOAE's logarithm AR spectrum with frequency for the normal hearing ears were obtained. Then the subject's logarithm AR spectrum with frequency and the suppressed logarithm AR spectrum with frequency curves were compared with the two normal-hearing curves' range respectively. The sensorineural hearing loss disease could be diagnosed and the defected site could be further located. A comparison was made between this technique and other clinical integration methods, and results were comparatively consistent.

有或无对侧声刺激瞬时诱发耳声发射的临床应用及AR谱分析

为了诊断和定位耳蜗和耳蜗后耳蜗两种主要的感音神经性听力损失的缺陷部位，提出了一种基于AR谱分析的瞬态诱发耳声发射(TEOAE)和对侧声刺激(CAS)抑制的TEOAE信号技术。首先，得到反映正常听力耳TEOAE的对数AR谱与频率关系信息和抑制后TEOAE的对数AR谱与频率关系的两条曲线的正态范围;然后分别将受试者的带频率的对数AR谱和带频率曲线的抑制对数AR谱与两条正常听力曲线的范围进行比较。对感音神经性听力损失疾病进行诊断，并进一步定位缺损部位。将该方法与其他临床整合方法进行比较，结果比较一致。
