| Descripción: |
Infrasound is discussed in terms of what it actually is, how the media has dealt with it and what those with limited knowledge say about it. The perception of infrasound occcurs at levels higher than the levels produced by wind turbines and there is now agreement amongst acousticians that infrasound from wind turbines is not a problem. Statements on infrasound from objectors are considered and it is shown how these may have caused avoidable distress to residents near wind turbines and also diverted attention from the main noise source, which is the repeating sound of the blades interacting with the tower. This is the noise which requires attention, both to reduce it and to develop optimum assessment methods. L’infrason est discuté en termes de ce qu’il est réellement, son traitement dans les médias et par ceux avec des connaissances limitée à son sujet. La perception de l’infrason est qu’il existe à des niveaux plus hauts que ceux produits par des éoliennes, mais il y a maintenant accord parmi les acousticiens que l’infrason des éoliennes n’est pas un problème. Des rapports sur l’infrason par des protestataires sont considérés et on montre comment ceux-ci ont pu causer de la détresse évitable aux résidants près des éoliennes et également divertir l’attention de la source principale de bruit: le son répétitif de l’interaction des lames avec la tour. C’est ce bruit qui exige de l’attention, pour le réduire et pour développer des méthodes optimales d’évaluation. |
