| description | Reverberation rooms are useful for measurement of the acoustic quantities of machines that operate in long cycles, however, current reverberation chamber design practices often lead to known issues with reproducibility and repeatability of measured data. The problem is that construction process of these laboratories is performed according to the relevant standards requirements which are mainly focused on the volume of the room or on the absorption coefficient value of the boundary surfaces. Nevertheless, the inner-laboratory reproducibility of acoustic data is very difficult to achieve even when these diffusivity quantifiers are satisfied. This paper presents a verification process of an acoustic laboratory which proportions, shape and construction material of boundary surfaces are not in compliance with standards in every detail. |
