Farm Noise Emissions During Common Agricultural Activities

TLDR

Noise injury in agriculture is a significant yet often unrecognized problem, with farmers and farm workers exposed to levels above recommended limits and experiencing higher rates of hearing loss than non‑farming peers. This study aims to collect up‑to‑date farm noise data to improve information available to farmers for reducing exposure and complying with OHS noise regulations. Researchers conducted visits to 48 farms, measuring ear‑level noise from operators and bystanders during typical activities, recording average and peak levels for 56 machinery types across 298 items. Key hazards include firearms, cabless tractors, workshop tools, small motors, pig handling, shearing sheds, older cabbed tractors, and heavy machinery; firearms without protection pose an urgent risk, and prolonged machinery use also threatens hearing, underscoring the need for farm noise management.

Abstract

Noise injury in agriculture is a significant yet often unrecognized problem. Many farmers, farm workers, and family members are exposed to noise levels above recommended levels and have greater hearing loss than their non-farming contemporaries. The aim of this study was to gather up-to-date information on farm noise levels and to enhance the quality of information available to assist farmers in reducing noise exposure and meeting Occupational Health and Safety (OHS) regulations regarding noise management. Farm visits were conducted on 48 agricultural establishments that produce a range of commodities. Noise levels were measured at the ears of operators and bystanders involved in typical activities on farms. The average and peak noise levels were measured for 56 types of machinery or sites of farming activity, totaling 298 separate items and activities. Common noise hazards identified included firearms, tractors without cabs, workshop tools, small motors (e.g., chainsaws, augers, pumps), manual handling of pigs, shearing sheds, older cabbed tractors, and heavy machinery such as harvesters, bulldozers, and cotton module presses. We found that use of firearms without hearing protection presents a pressing hearing health priority. However, farming activities involving machinery used for prolonged periods also present significant risks to farmers' hearing health. Noise management strategies on the farm are essential in order to prevent noise injury among farmers.
