Generally, the inner surfaces of a room receive sound from a wide diffuse field typified by the figure below:
Consequently, this chapter describes a relevant sound absorption method that would be used to determine the sound absorption coefficient emanating from the above incidence. This method is also reffered to as the reverbaration room method. Ideally, the experiment is performed in a â€œreverbaration room with highly irregular or non parallel surfaces and/or suspended, sound defusing elementsâ€ (Finn et al. 103). The assumption in this experiment is that the varied sound field would concur with the requirements stipulated in Subineâ€™s reverberation formula. To derive Subines formula we assume that a vacant reverberation room has the following parameters; an absorption coefficient, Î±empty, inner surface area, S, and has a volume, V, then the below equation is derived
