This study analyzes the association of noise pollution level with hearing threshold level, blood oxygen concentration, heart pulse rate, systolic and diastolic blood pressure on workers in six departments in Jenin hospitals. The six departments are the intensive care units (ICU), neonatal care units (NICU), operating rooms (OR), laboratory (Lab), emergency and outpatient clinic. The sound pressure level (SPL) values in all studied hospitals are high compared with the recommended value which is 45.0 dB(A) in the daytime. The hearing threshold level, blood oxygen concentration, heart pulse rate and blood pressure (Systolic and Diastolic) were measured for 117 workers (61 males and 56 females) which is the sample of workers in hospitals in Jenin city. The ages of workers are ranged from 20 to 65 yr. The duration of employment of those workers in the current job is ranged from 1 to 38 yr. In this study HTL, SpO2%, SBP, DBP and HPR are correlated positively (p-value < 0.050) with the occupational noise levels in all studied hospitals. Whereas the Pearson coefficient correlation R value of HTL, SpO2%, SBP, DBP and HPR in all selected hospitals are ranged from 0.857 to o.938 of HTL, from 0.405 to 0.861 of SpO2%, from 0.754 to 0.983 of SBP, from 0.703 to 0.837 of DBP and from 0.496 to 0.938 for HPR.
