Abstract:
Over the past three decades, a biomedical research team based in Portugal has been studying the effects of low frequency noise (LFN) exposure. Initially prompted by the signs and symptoms observed among a population of aeronautical technicians, by the mid-1990s, study populations included commercial airline pilots and flight attendants. In 2001, the team began receiving complaints from families regarding LFN in their homes, and subsequently, the inquiry was widened to include residential exposures. In general, LFN levels in residential exposures are lower than those observed in occupational environments. On the other hand, occupational environments provide a recovery time at the end of the work-shift, while residential exposures remain present , even during the all-important sleep time. The Portuguese wind turbine (WT) case began in 2007, a follow-up was accomplished in 2010, and the Portuguese Supreme Court of Justice ruled, in 2013, that all WTs associated with this legal case had to be removed from the vicinity of this residential property. During that time, clinical evaluation of the family was performed with pertinent and objective medical tests. Later, the animals living in this residence were clinically evaluated, including histological analyses. The data collected within the scope of this Portuguese WT case corroborates much of the pre-existing results regarding the biological response to LFN exposure.
