THE DESIGN OF CLOSE FITTING ACOUSTICAL ENCLOSURES
Abstract
Theoretical methods of analyzing the insertion loss of tight fitting enclosures which are available in the literature are presented and compared. A new three dimensional model incorporating wall absorption is derived. An experimental apparatus designed to verify the results from this model is described. After comparing the results from the theory and experiment, it is concluded that the three dimensional model accounts for the effects of enclosure size, source location, measurement location and wall impedance well but fails to consider sound transmission through the side walls of the enclosure and non-locally reacting absorption material.
