Currently most of the generators are operating at noise levels 90 dB which are far above the recommended noise level standards in developing nations residential areas, working environment like in office setups and learning environments. The current acoustic enclosures are only cooling internally using a fan, imbalances due to rotating components of the generator and the vibrations from the engine transmitted to the frame of the enclosure. As a result there is noise produced due to imbalances, vibrations and heat build-up in the enclosure. The proposed solution will curb noise problem using composite sound wall panels and use a heat exchanger to take out heat building in the acoustic enclosure. The important consideration for the enclosure design involves the heat transfer characteristics. This is because the design of an acoustic enclosure is striking a balance between the thermal aspect and sound.
