- In the development of sound isolation type generators, a three-division case structure divided into two cool zones and one hot zone was studied. This study was aimed at achieving compatibility between sound isolation and cooling capabilities that are in a trade-off relationship. Sound isolation of 12.1 dB(LWA) was achieved by this structure, while obtaining equivalent cooling capabilities to that of open type generators. As a result of adopting this new generator structure for India domestic consumption, the compliance with the Indian noise regulation phase II was achieved for the first time by a mass produced generator.
