| Abstract |
This study deals with the changes in temporary hearing threshold (TTS2), upright body posture sway amplitudes in the X and Y direction, heart rate, R-wave amplitude, systolic and diastolic blood pressure, pulse pressure and the index characterising haemodynamic activity, when the subjects were exposed to noise alone, to vibrations alone or to simultaneous noise and vibration. The TTS2 values at 4 and 6kHz increased as a result of simultaneous exposure to noise and vibration more than as a result of exposure to noise alone. Amplitudes of body upright posture sway changed after exposure to vibration alone, and after exposure to noise alone. The changes in the heart rate, R-wave amplitude and blood pressure values also depended on the bandwidth of the vibration, the number of consecutive exposures and on whether the subjects were simultaneously exposed to noise in addition to vibration. As a rule, the effects of sinusoidal vibration differed from those due to stochastic vibrations. |
