This study by the Kuopio Regional Institute of Occupational Health examined noise emissions from leaf blowers and other gardening equipment. Testing of nine leaf blowers revealed noise exposure levels between 93-102 dB(A), with the highest levels from 2-stroke engines. These engines emitted low-frequency tonal noise components, which penetrate walls and are perceived as particularly irritating. The study highlights the significant noise emissions from leaf blowers, contributing to public complaints and recognizing the need for improved noise control in such equipment.

The Grand Jury report outlines the health and environmental hazards of gas-powered leaf blowers in Orange County, citing toxic emissions, particulate pollution, and harmful noise levels. Exhaust from these blowers is likened to the pollution of 17 cars per hour. The report calls for local governments, school districts, and community colleges to stop using gas-powered blowers in favor of cleaner alternatives like rakes, brooms, or electric blowers. It highlights successful compliance in cities that have banned the devices, emphasizing the need to protect public health and improve quality of life.
