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 (VAD) . . .

Low frequency noise legislation
Author: Alves-Pereira, Mariana; Motylewski, Jersy; Kotlicka, Elzbieta; and Castelo Branco, Nuno
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 . . .

Public health and noise exposure
Author: Alves-Pereira, Mariana; and Castelo Branco, Nuno
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,

Industrial Wind Turbines, Infrasound and Vibro-Acoustic Disease (VAD)

Excessive exposure to infrasound and low frequency noise (ILFN, defined as all acoustical phenomena occurring at or below the frequency bands of 500 Hz) can cause vibro-acoustic disease (VAD). [1]
Research into VAD has been ongoing since 1980, conducted by a . . .
