Study of Sound Isolation Structure for Engine Generators

Article of Honda R&D Technical Review Vol.15 No.2

Summary

In a development of sound isolation type generators, three-division case object structure that has divided two cool zones and one hot zone was newly studied. This study was aimed at establishment of compatibility at high level between sound isolation and cooling capabilities that are in a trade-off relationship. Sound isolation of 12.1dB(A) was achieved according to this structure, securing the equivalent level of cooling capabilities to that of open frame type generators. As a result of adopting the new structure to the generators for domestic consumption for India, the Indian noise regulation phase II has been accomplished for the first time in the entire world.
