Application of SWT and MISO Methods for Measurement and Analysis of Electro-Acoustic and Audio Systems

Popis výsledku v původním jazyce

This contribution deals with performance evaluation of electro-acoustic and audio systems with non-linearities by a combination of two existing methods: Swept Sine Technique (SWT) and Multiple Input Single Output (MISO) nonlinear modelling. This method has been used for analysis of various components of electro-acoustic and audio systems. In the first application described in our contribution, this test method was used for a detailed analysis of transfer functions of a complete electroacoustic test system with an artificial head. This system is used for the analysis of spatial perception as well as determination of a signal compression impact on its perception. In the next application, this test method was used for measurement and evaluation of the whole transmission chain from studio all the way to the listener. The signal source was a studio recording CD that was transmitted by FM radio to the listener's receiver where it was demodulated, monitored and analyzed.
