Results of 200 tests made to determine acoustic principles that must be considered; noise characteristics of mowers and their components were determined with aid of Armour Research Foundation reverberation chamber; engine, blade, deck, and muffler were studied and six major noise components established; two components of engine noise can be reduced by using cover for exposed engine above deck; noise control abilities defined as cover and deck factors.
