Noise measurements were made on seven ultra-low volume ULV insecticide dispersal machines in order to identify noise hazardous conditions. With the exception of the Northeastern Associates Cardinal ULV Sprayer all of the machines were gasoline-driven and the predominant source of noise from them was identified as the engine exhausts. All of the gasoline-driven ULV machines, by US Army standards, constituted a hearing hazard to personnel in close proximity such as the jeep driver or operator and maintenance personnel. Maintenance and operating personnel in close proximity to the gasoline-driven ULV machines must wear hearing protective devices.
