The aim of this study was to investigate the level of noise exposure and its relationship with job stress, changes in blood pressure and heart rate among woodworking workshop workers.

In this cross-sectional-analytical-descriptive study, 140 employees of a lumber workshop in Mazandaran province were selected and divided into case and control groups. Demographic information of employees was collected by questionnaire. Systolic and diastolic blood pressure were measured using mercury sphygmomanometer. Heart rate of the case and control groups was measured by Beurer pulse meter. The results were analyzed using SPSS software.

The results of noise measurements showed that the mean noise exposure in workers from 8-hour shifts was 92.11 dB and among non-exposed group was 74.48 dB. The mean systolic and diastolic blood pressure in the control and exposure groups were 124, 126, 80 and 82, respectively. Also, the mean heart rate of the studied groups was 74.9 and 75.83 beats per minute, respectively. There was no significant difference in systolic and diastolic blood pressure and heart rate between the two groups, (p> 0.05).

Based on thefindings, the rate of systolic and diastolic blood pressure, as well as the heart rate and stress levels were higher in the exposed group as compared with the control group; however, the difference between systolic, diastolic blood pressure and heart ratebetween the two groups was not statistically significant. There was a significant difference in stress. It was found to be consistent with the results of some previous studies
