Background Noise has the potential to affect the comfort and health of workers. The objective of this research was to determines the effects of noise on the concentration levels of both chainsaw operators and harvesting workers in industrial forest plantation, North Sumatra, Indonesia. Methods This experimental study included 20 respondents which consisted of 10 chainsaw operators/helpers and 10 harvesting workers. All respondents were exposed to the sound of a chainsaw in three different conditions (idle, half gas and racing conditions) with and without personal protective equipment (PPEs: earmuffs, ear plugs and without PPE). The sound intensity produced by the chainsaw and the noise received by the respondents were measured using a sound level meter. Respondents’ perception toward noise was recorded using a Likert scale. Respondents’ concentration level was assessed by giving 25 math-questions to be answered within 10 minutes. Wilcoxon sign rank test was used to analysed paired data. Results The average sound intensity received by respondents’ left and right ears were lower than the average sound intensity produced by the chainsaw. The use of earmuffs leads to better perception towards noise when compared with the use of earplugs and the absence of any PPE. Based on Wilcoxon test, the noise did not have significant impact on the concentration level of chainsaw operators, whilst the contrary result is true for harvesting workers. Conclusions The research indicated that although the noise produced by the chainsaw was considered noisy for both chainsaw operators and harvesting workers, it did not have a significant effect on the concentration level of chainsaw operators and only affected the harvesting workers. Therefore, given that the harvesting workers were still affected by the noise, noise control measures are still needed to ensure occupational safety and health for the workers.

“…In a study of 348 workers at a crumb rubber factory in Padang, Indonesia, a correlation was found between noise exposure and work fatigue (t = 2.024; p = 0.046 < 0.05). The results showed that 26.19% of the workers experienced mild fatigue, 71.43% experienced moderate fatigue, and 2.38% experienced severe fatigue (Ihsan et al, 2021). A study in Iran that compared administrative department workers exposed to noise of 51.42 dB(A) (n = 26) and production department workers exposed to noise of 79.78 dB(A) (n = 26) showed significant differences in work fatigue using the Mann Whitney U Test (p = 0.000) (Heidari et al, 2021).…”

Occupational fatigue remains a prevalent concern in occupational health. This study investigated the association between noise intensity, blood glucose levels, body mass index (BMI), and lactate levels as an indicator of occupational fatigue among textile industry workers in Surakarta, Indonesia. An analytical observational study with a cross-sectional design was conducted, with 82 participants recruited from a local textile industry. Multivariate analysis using multiple binary logistic regression revealed that noise intensity, blood glucose levels, and BMI were significant risk factors for occupational fatigue, as indicated by elevated lactate levels. These findings highlight the importance of noise reduction measures, a healthy lifestyle, and regular monitoring of blood glucose levels and BMI to mitigate occupational fatigue among textile industry workers

Background: Noise has the potential to affect the comfort and health of workers. The objective of this research was to find out the effect of noise caused by the timber harvesting process using chainsaws on the concentration of workers in an industrial forest plantation. Methods: This experimental study included 20 respondents which consisted of 10 chainsaw operators/helpers and 10 non-chainsaw operators. All respondents were exposed to the sound of a chainsaw in three different conditions (idle, half gas and racing conditions) with and without personal protective equipment (PPE). The sound intensity produced by the chainsaw and the noise received by the respondents were measured using a sound level meter. Respondents’ perception toward noise was recorded using a Likert scale. Respondents’ concentration level was assessed by giving 25 math-questions to be answered within 10 minutes. Wilcoxon sign rank test was used to analysed paired data. Results: The average sound intensity received by respondents’ left and right ears were lower than the average sound intensity produced by the chainsaw. The use of earmuffs leads to better perception towards noise when compared with the use of earplugs and the absence of any PPE. The Wilcoxon test result showed that noise did not have significant impact on the concentration level of chainsaw operators, whilst the contrary result is true for non-chainsaw operators. Conclusions: The research indicated that although the noise produced by the chainsaw machine was considered noisy for both chainsaw operators and non-chainsaw operator, it did not have a significant effect on the concentration level of chainsaw operators and only affected the non-chainsaw operators. Therefore, given that the non-chainsaw operators were still affected by the noise, noise control measures are still needed to ensure occupational safety and health for the workers.
