520 $aIn recent years new methods based on signal processing technical have been developed to measure the normal acoustic impedance of materials. These methods proved to be consdierably faster easier to implement than the SRW method they replace. Mathematical, hardware and software aspects of these techniques are discussed and results obtained over a frequency range of 200-4000 Hz for several architectural materials are presented.
