This study finds the relation between the occupational noise level and the systolic and diastolic blood pressure (SBP and DBP), heart pulse rate (HPR), blood oxygen saturation (SpO2%), and hearing threshold level (HTL) of selected students in the schools in Ramalla county in Palestine. The study sample consisted of 360 students aged 15 to 17 years old, distributed equally in six schools (3 males and 3 females). Studied schools were selected randomly in three different regions. The measured sound pressure levels (SPL) in all tested schools were found to be above the standard of international acceptable levels. In this study SBP, DBP, HPR, SpO2% and HTL are correlated positively (P- value < 0.050) with the occupational noise levels in all studied schools. Whereas the Pearson coefficient correlation (R) value of SBP, DBP, HPR, SpO2% and HTL in all selected schools are ranged from 0.529 to 0.785 for SBP, from -0.198 to 0.825 for DBP, from 0.712 to 0.879 for HPR, from -0.007 to 0.290 for SpO2% and from 0.722 to 0.994 for HTL.
