Abstract

Mathematical analysis on the effects of human health due to traffic noise is explained in the present paper. Locations at various noisy zones have been indentified to adopt few individuals response due to longer exposure to the traffic noise. The study is aimed at computing the variations of physiological parameters due to noise effects. These effects are mainly studied as velocity of blood flow at constricted location in the human artery, the flux of the flow, wall shear stress, pressure gradient are calculated for various noise data recorded on NH-4. The study is focussed to estimate the changes in systolic and diastolic blood pressures due to this constriction. The constriction ( narrowing of the artery) is alos due to the longer period exposure to the noise at the level (≥ 65dB (A)). The encountered effects are noticed at greater than 80-100dB (A) levels causing the vibrational energy into cochlea of the ear. The prolonged noise exposure gives the change in physiological condition mainly the threshold shift in the diastolic blood pressure as 9mm Hg which becomes the permanent onset of diastolic blood pressure. The model consists of analytical formulations for equations of motion and analytical solutions have been carried out ot copute the values of velocity, flux, wall shear stress, pressure gradient of blood flow in artery due to traffic noise effect.
