Extracts from Leventhall Report

Extract from Leventhall et al 2003 report for the UK Dept of Food and Rural Affairs on the effects of Low Frequency Noise on Human Health

“12.2 Effects on health. In an epidemiological survey of low frequency noise from plant and appliances in or near domestic buildings, the focus was on health effects (Mirowska and Mroz, 2000). …

A control group of dwellings had comparable conditions to the test group, with similar A-weighted levels, except that there was no low frequency noise. There were 27 individuals in the test group and 22 in the control group.

The test group suffered more from their noise than the control group did, particularly in terms of annoyance and sleep disturbance. They were also less happy, less confident and more inclined to depression.

The comparison of the symptoms between the tested group and the control group show clear differences, as in Table 5. “

The symptoms in this table and pattern of exposure are the same as those later described by Dr Nina Pierpont as “wind turbine syndrome“.   Professor Leventhall has now agreed with this publicly on numerous occasions, including while being cross examined in a court case in Ontario  (see http://www.wind-watch.org/documents/audit-national-health-and-medical-research-council-public-statement-2010-and-rapid-review-2010/ ).

“These results are extremely interesting as an epidemiological survey of an affected and a control group. Table 5 shows very adverse effects from low frequency noise levels which are close to the threshold and which do not exceed A-weighted limits.”
