The analysis of oae signal is the composition of hearing physiology and audiology 对耳声发射的研究是对听觉生理及病理研究的一部分。
The discovery of otoacoustic emissions ( oae ) is one of the most important progress in hearing physiology and audiology 耳声发射现象的发现是听觉生理学和听力学近20年最重要的进展之一。
Sixteen patients showed some degree of oarian supply to the uterus , and nine of them had unilateral or bilateral oae 16个病人显示了一定程度的卵巢补给子宫,他们中的九个人有单侧面的双侧的子宫动脉栓塞。
The oae diagnoses , which is simple , speedy , hurtless , and can be applied to all ages , has great clinic worthiness 由于耳声发射检测方法简便、迅速、无创,且适用人群广,在临床中具有极大的使用价值。
But its research and clinic application has been badly restricted by these days " oae test instrument , either ponderous or costliness 但是目前耳声发射检测产品大都功能单一、灵活性差、价格昂贵,严重地制约了对耳声发射现象的研究和临床应用的推广。
In order to eliminate these disadvantages , we present a new intelligentized oae test instrument based on correlative research in the world in the last years . our otoacoustic hearing measurement instrument comprises two parts 针对这些不足,我们在基于对传统及近几年国内外相关产品研究的基础之上,提出了一种新型的全智能控制耳声发射检测仪的设计。
Compact in configuration , mightiness in function , convenience in manipulate and high resolution , high efficiency , low cost are all the characteristics of this instrument . in the end , we give a brief introduce about some common analysis methods on oae signal . and lay a emphasis on wavelet and improved wigner - vill used in the analysis of soae and teoae , comparing with the tradition method , these new time - frequent methods have better time - frequent characteristic , are fitter for the oae signals 最后,该文分别对耳声发射信号的常用分析方法进行了介绍,并重点介绍了用小波变换、改进的维格纳分布等方法分别对soae信号、 teoae信号进行分析的情况,与传统的处理方法相比较,时频分析方法由于具有较好的时频分辨率,更适合于耳声发射信号的分析。
