Abstract
The image source technique is used for determining the sound field in a closed environment. The sound field is determined by the sum of the reflections of the sound rays on the surfaces of the environment. In this paper the sound field is analysed in a closed environment with the technique of complex images. The sound field is given from the sum in amplitude and phase of the sound rays that are reflected from the surfaces of the room. The results of experimental measurements in a scale model are shown in comparison with the sound field models obtained by the energy method and by the complex images. The complex image method is a good tool for studying the propagation of the sound a closed environment.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
