瞬态诱发耳声发射(OAE)的线性部分被认为是在构成波分量的特征位置附近通过相干反射产生的。由于耳蜗的张力组织，高频回波早于低频回波；然而，由于相干反射的随机性，TEOAEs的瞬时频率(IF)和振幅包络都存在波动。多重反射分量和同步自发辐射使得用线性变换提取中频变得更加困难。本文提出将TEOAEs模型化为{\em本征模型函数}的和，并用一种称为频率和时间集中的{非线性时频分析}技术对其进行分析。当用合成OAE信号（可能含有多个振荡分量）进行测试时，该方法能够在时频平面上产生单个分量的清晰可视化轨迹。此外，当信号存在噪声时，本文提出的方法与现有的线性和双线性方法在估计波动中频的精度方面进行了比较。结果表明，当信噪比为10 dB或以下时，ConceFT在最优传输距离方面优于上述方法，误差减小10～21%。

英文摘要：
  The linear part of transient evoked (TE) otoacoustic emission (OAE) is thought to be generated via coherent reflection near the characteristic place of constituent wave components. Because of the tonotopic organization of the cochlea, high frequency emissions return earlier than low frequencies; however, due to the random nature of coherent reflection, the instantaneous frequency (IF) and amplitude envelope of TEOAEs both fluctuate. Multiple reflection components and synchronized spontaneous emissions can further make it difficult to extract the IF by linear transforms. In this paper, we propose to model TEOAEs as a sum of {\em intrinsic mode-type functions} and analyze it by a {nonlinear-type time-frequency analysis} technique called concentration of frequency and time (ConceFT). When tested with synthetic OAE signals {with possibly multiple oscillatory components}, the present method is able to produce clearly visualized traces of individual components on the time-frequency plane. Further, when the signal is noisy, the proposed method is compared with existing linear and bilinear methods in its accuracy for estimating the fluctuating IF. Results suggest that ConceFT outperforms the best of these methods in terms of optimal transport distance, reducing the error by 10 to {21\%} when the signal to noise ratio is 10 dB or below.
