Introduction: The agricultural tractor is one of the most commonly used vehicles on farms and one of the most prominent sources of noise. This article presents an exemplary assessment of the audible and infrasonic noise levels in the cabins of selected modern wheeled agricultural tractors. Materials and Methods: Operator-perceived audible and infrasonic noise levels in the cabins were examined for 20 types of modern tractors during typical conditions of work. The tractors had been in use for no longer than 3 years, with rated power between 96 kW and 227 kW, designed and produced by world-renowned companies. Noise level measurements were performed in accordance with PN-EN ISO 9612:2011 (ISO 9612:2009). Results: Audible noise levels (A-weighted) ranged from 62.1 to 87.4 dB-A (average: 68.2 to 83.8 dB-A) for different work tasks. The factors influencing noise levels include performed tasks, soil, weather conditions and the skills of individual drivers. In spectrum analysis, the highest noise levels occurred at frequencies 250 Hz, 1 and 2 kHz. Infrasound noise levels (G-weighted) ranged from 87.3 to 111.3 dB-G. The driver-experienced exposure to infrasound was found to increase significantly when the vehicle was in motion. Conclusions: Average audible noise levels have no potential to adversely affect the hearing organ during tasks performed inside the closed cabins of the analysed modern agricultural tractors. Due to the relatively low audible noise levels inside the cabins of modern agricultural tractors, non-auditory effects are the only adverse symptoms that can develop. Modern agricultural tractors emit considerable infrasonic noise levels. All tractors introduced into the market should be subjected to tests with regard to infrasonic noise levels.

This paper summarizes the currently available knowledge on the impact of infrasound (IS) and low frequency noise (LFN) on human health and well-being. This narrative review of the literature data was based on the selected, mostly, peer-reviewed research papers, review articles, and meta-analyses that were published in 1971–2022. It has been focused on the results of epidemiological studies concerning the annoyance related to infrasound and low frequency noise, as well as their impact on the cardiovascular system and sleep disorders. Particular attention was also paid to the latest research results and specific sources of IS and LFN, i.e., wind turbines.

Niniejsza praca podsumowuje dostępną wiedzę na temat wpływu infradźwięków i hałasu niskoczęstotliwościowego (HNcz) na zdrowie i samopoczucie ludzi. Podstawą tego narracyjnego przeglądu piśmiennictwa były wybrane, głównie recenzowane prace badawcze, artykuły poglądowe i metaanalizy opublikowane w latach 1971–2022. Uwagę skoncentrowano na wynikach badań epidemiologicznych dotyczących dokuczliwości przypisywanej infradźwiękom i HNcz, a także ich wpływowi na układ sercowo-naczyniowy i zaburzenia snu. Szczególną uwagę poświęcono także ostatnim wynikom badań i swoistym źródłom infradźwięków i HNcz, tj. turbinom wiatrowym.

This narrative review of the literature data was based on the selected, mostly, peer-reviewed research papers, review articles, and meta-analyses that were published in 1973–2022. It has been focused on infrasound perception, annoyance attributed to infrasound and low-frequency noise, as well as their effects on the cardiovascular system and sleep disorders. Particular attention was also paid to the latest research results and specific sources of infrasound and LFN, i.e., wind turbines.
