The author has made tests for an artificial head transfer system which is modelled on a Chinese male on its main physical behaviour such as frequency responses, frequency response differences between the front and the rear incidences, as will as on its important hearing behaviour such as localization, the perception of distance and room dimensions. The results verify that this kind of artificial head transfer system can be used as one of effective tools of acoustic evaluation researches for halls. 展开更多

A new method to obtain numerical solution of Acoustic Transfer Function (ATF) by BEM is presented. For a simply supported panel backed by a rectangular cavity at low frequency band (0-200 Hz), the frequency property of ATF is analyzed. The relation between the accuracy of the rapid evaluation of sound field and the discretization schemes of the vibrational panel is discussed. The result shows that the method to obtain ATF and the rapid evaluation of sound field using the ATF is suitable to low frequency band. If an appropriate discretization scheme is choosed based on the frequency involved and the effort to obtain ATF, the accuracy of the rapid evaluation of sound field is acceptable. 展开更多
