IMPACT SONORE D’UN AEROGENERATEUR SUR LE MILIEU AMBIANT

Abstract

Some disturbing facts reported by the populations subjected to noise who complains. It appears that, on some days, these people find a very intense noise level much higher than that to which they are usually submitted. On a wind farm with multiple turbines chance determine the moments or the propeller blades, past the towers, generate impulse noise of each machine. The rotation of these machines is synchronous and phase angles between helices are stable over a significant time. External circumstances (speed and wind direction, speed of sound for the temperature and pressure of the moment) follows determine the time of transmission of such noise between each turbine and place of living considered. it may be that the superposition of these conditions is that the impulsive noise of several vehicles, if not all arrive at the same time instead of life in question; in other words that the impulsive noise of several, or all gears, find themselves in line in place of life. They then have come correlated noises. so . What is the noise impact of wind turbines on a place of lif
