Since most of the equipments are usually installed in rooms or enclosed plants, the effect of an enclosure is important. Absorptive surface of the enclosure can reduce levels to the extent of 5 dB(A) which is quite significant. Effectiveness of enclosures in sound varies with the frequency of sound and the shape, size, laying pattern of sound absorbing material, which is put on the walls of the enclosure. The sound absorbing material accomplishes little shielding if there is no acoustical absorption within it. Acoustical absorbents when applied to the interior surface of the enclosure adsorb some of the energy and the noise level within the enclosure builds up only by the energy not absorbed. This paper elucidates the procedure of developing an enclosure to study its performance in attenuating sound at varying conditions. The results found encouraging and such enclosures can be developed for plant machineries by the plant personnels without getting confused by the claims and rhetoric of advertisements of big companies engaged in developing such items.
