In-Home Wind Turbine Noise Is Conducive to Vibroacoustic Disease
Author: Alves-Pereira, Mariana; and Castelo Branco, Nuno
Abstract of paper to be presented at the Wind Turbine Noise Conference 2007, Lyon, France, September 20-21, 2007: Introduction. This team has been systematically studying the effects of infrasound and low frequency noise (ILFN, <500 Hz) in both human and animal models since 1980. Recently, yet another source of ILFN has appeared: wind turbines (WT). Like many other ILFN-generating devices, WT can greatly benefit humankind if, and only if, responsible and intelligent measures are taken for their implementation. Vibroacoustic disease . . .

Paper accepted for Inter-noise 2007, 28-31 August, Istanbul, Turkey Abstract: Legislation regarding low frequency noise (LFN, <500 Hz including infrasound), when existent, is highly deficient. Not only is it expressed in dBA, actually defeating the purpose of evaluating LFN, but no concrete measures are prescribed if excessive LFN is identified. The status quo notion that acoustical phenomena are only harmful when perceived by humans cannot be sustained given current scientific facts. The purpose of this report is to demonstrate just . . .

Paper accepted for Inter-noise 2007, 28-31 August, Istanbul, Turkey Abstract: Noise exposure is known to cause hearing loss and a variety of disturbances, such as annoyance, hypertension and loss of sleep. It is generally accepted that these situations are caused by the acoustical events processed by the auditory system. However, there are acoustical events that are not necessarily processed by the auditory system, but that nevertheless cause harm. Infrasound and low frequency noise (ILFN, <500Hz) are acoustical phenomena that can . . .

Noise & Health 2004; 6(23): 3-20 Vibroacoustic disease (VAD) is a whole-body, systemic pathology, characterized by the abnormal proliferation of extra-cellular matrices, and caused by excessive exposure to low frequency noise (LFN). VAD has been observed in LFN-exposed professionals, such as aircraft technicians, commercial and military pilots and cabin crewmembers, ship machinists, restaurant workers, and disk-jockeys. VAD has also been observed in several populations exposed to environmental LFN. This report summarizes what is known to date on VAD, LFN-induced pathology, . . .
