Abstract

In this work, we present a method of measurement of nonstationary acoustic impulse responses identified by the fast version of the Recursive Least Squares algorithm (FRLS), using professional acoustic equipment. This measurement bench realized in a deaf room presents several tests of capability of adaptive algorithm to tracking the nonstationarities of true system to be identified. The tests of tracking capability obtained are stronger compared to what is encountered in real life and can be used in several applications.

非平稳声脉冲响应的测量与自适应识别

在这项工作中，我们提出了一种使用专业声学设备测量通过递归最小二乘算法（FRLS）的快速版本识别的非平稳声脉冲响应的方法。该测量台在聋人房间中实现，对自适应算法跟踪待识别真实系统的非平稳性的能力进行了几次测试。与现实生活中遇到的情况相比，所获得的跟踪能力测试更强，可以用于多种应用。
