Difference in cardiovascular parameters between pre- and post-test for different types of noise.

		A		B		C
		75dB	90dB	75dB	90dB	75dB	90dB
All values are presented as mean (standard error mean). SBP: systolic blood pressure; DBP: diastolic blood pressure; HR: heart rate * p-value < 0.05 compared to exposure to background noise (< 55 dB) using one-way ANOVA.
