Abstract

The purpose of this study was to determine the daily noise exposure levels in olive harvesting and to evaluate its effects on employees' health. The sound pressure levels (dBA) at the ear level of the employees were measured during olive harvest operations performed by hand-held, self-propelled and tractor-driven machines. It was determined that equivalent sound pressure levels and daily personal noise exposure levels at the operator ear level were in the range of 74-88 dBA and 66-82 dBA, respectively. These values for other employees ranged from 71 to 81 dBA and 65 to 75 dBA. It was determined that the hand-held and tractor driven machines driven by internal combustion engines had higher noise parameters compared to other machines, and the lower exposure action value was exceeded in these machines. The study showed that the health and work efficiency of the employees could be adversely affected, due to prolonged exposure during olive harvest activities.

Highlights

Harvesting activities covering 70% of the production process constitute the last and most important part of olive cultivation (Saraçoğlu, 2001)
All factors that can contribute to noise exposure were analyzed (OSHA, 1998), and it was determined that the task-based strategy was suitable for the study, According to the task-based measurement strategy, all tasks performed by the employees within a working day were defined, the working time of each task was determined precisely, and sound pressure level measurements were made for each task separately
It was concluded that the health and work efficiency of the operators and other employees were adversely affected in olive harvesting mechanization

Summary

Introduction

Harvesting activities covering 70% of the production process constitute the last and most important part of olive cultivation (Saraçoğlu, 2001). In parallel with the technological advances, there have been important developments in olive harvest mechanization, and in recent years, traditional vehicles have been replaced by hand-held, tractor driven and self-propelled machines. Agric Nat 25 (2): 348-356, 2022 the use of tractor driven and self-propelled machines has become widespread due to the higher work capacities. While these technologies and innovations provide important advantages such as saving time and decreasing the dependence on labor, they can have some undesirable effects on employees (SolaGuirado et al, 2014; Bernardi et al, 2018). Various studies have been carried out to determine the noise levels (range from 56-90 dBA, Leq) caused by various self-propelled and hand-held machines. The examples include wine and cereal growing (Franzinelli et al, 1988), hand-held olive harvesters (Saraçoğlu, 2001), motor scythes (Çakmak and Alayunt, 2009; Çakmak et al, 2011), combine harvesters
