Recent Improvements in Silencing Engine-Driven Generators

L. D. Grignon

A gasoline engine-driven, 120-v, d-c generator of 150-kw output for set lighting on location has been improved. The enclosing wall structures, materials and carburetor air-intake were changed. When mounted on a trailer the exhaust and radiator and noise are considerably reduced by methods described. The improvements permit sound recording with the generator as close as 250 ft under reasonably favorable circumstances and not exceeding 750 ft for critical conditions. Considerable saving in production costs results.
