Effect of impulse noise on water consumption and blood pressure in the female rat

Our laboratory has previously measured significant elevations in plasma angiotensin II concentrations accompanying brief intense noise exposures in rodents. The present investigation was designed to evaluate the effects of noise induced elevations in water consumption and blood pressure in normotensive female rats. The durations of noise exposure simulated an industrial setting in which impulse noise is present. The results indicate significantly increased blood pressure and water consumption with two weeks of noise exposure compared to shorter exposure durations.
