Sentences with phrase «infrasound noise emissions»

«Whilst the aerodynamic noise from a rotating turbine blade produces energy in the infrasound range, measurements of infrasound noise emissions from modern upwind turbines indicates that at distances of 200 metres, infrasound is in the order of 25 dB below the recognised perception threshold of 85 dB (G) and other similar recognised perception thresholds (Hayes Mckenzie Partnership Ltd, 2006).

Some have published research demonstrating that wind turbines emit infrasound and low - frequency noise (ILFN) and that these emissions resonate inside homes to the point where residents sometimes resort to sleeping on the veranda rather than in their bedrooms.

The ONLY justification for wind power — the massive subsidies upon which it entirely depends (see our post here); spiralling power prices (see our post here); and the suffering caused to neighbours by incessant low - frequency noise and infrasound (see our post here)-- is the claim that it reduces CO2 emissions in the electricity sector.

Despite the reports of sick residents and concerned medical practitioners since 2003, it is only within the last 6 — 12 months that there has been any independent acoustics information about what the exposures are of these sick residents to both infrasound and low frequency noise emissions from the turbines.
