Zahteve za odmevnice in pristop k projektiranju odmevnice akustičnega laboratorija InnoRenew CoE

Several important acoustic quantities and parameters are measured in the acoustic environment of a reverberation chamber. In the chamber the presence of the diffuse sound field is assumed, which is difficult to justify due to the absence of well accepted diffuse sound field quantifiers. As a consequence, it is also difficult to define exact design goals for reverberation chambers. In the article some requirements for reverberation chambers are summarized as defined by the standardized measurement procedures, such as for determining the diffuse sound filed absorption coefficient of materials (α), sound power of noise sources (LW ) and random-incidence scattering coefficients of surfaces (s). Furthermore, several aspects of the initial acoustic design of the reverberation chamber emerging as part of the acoustic laboratory of InnoRenew CoE are presented.Pages 277-279
