This study reports the relationship between occupational noise level with arterial blood pressure (systolic anddiastolic), and heart pulse rate for sample of doctors (male and female) in their dental offices which was chosenrandomly in Jenin City. The mean age of the sample is 40 year. The mean duration of their serving is 13.8 year.Measurements for the noise levels were obtained. The noise level was between (90.5 - 91.7) dB. The arterial bloodpressure (systolic and diastolic), and heart pulse rate were measured before and after exposure to noise for fourhours. Strong positive correlation (Pearson Correlation Coefficient) was found for all of the measured variables. Themean systolic and diastolic blood pressure, heart pulse rate for the experimental sample are correlated positivelywith the noise pollution level (R= 0.629 for systolic, R=0.475 for diastolic), and for heart pulse rate (R= 0.560). Thisstudy showed that there are significant shifts in mean values of systolic blood pressure, diastolic blood pressure, andheart pulse rate before work and four hours after work. The systolic blood pressure mean for the experimentalsample is increased by 4.4 mm-Hg, while the diastolic blood pressure mean is increased by 3.8 mm-Hg, the heartpulse rate mean is increased by 3.6 beat/min. In addition, significant interactions were found between mean valuesof arterial blood pressure (systolic and diastolic), heart pulse rate, doctors' ages, and duration of serving year.Email addresses
