WHO Environmental Noise Guidelines 2018
World Health Organization - Regional Office for Europe
The long-awaited latest guidance from the World Health Organization was released yesterday (10th October 2018). Of particular interest to Hayes McKenzie is the section specifically concerned with wind turbine noise. A quick flip to Section 34 on page 77 tells you all you need to know which is that the WHO are conditionally recommending that turbine noise should not exceed an Lden of 45dB. Lden is the average noise level over one year, where noise during the evening is penalised with a +5 dB correction, and a +10dB correction applied for noise at night. In the case of wind turbine noise, which is continually varying from day to day, depending on the wind speed and direction, it will be almost impossible to establish compliance with this limit through measurement alone. As a means of 'impact' assessment, however, it has some distinct advantages which are discussed in Andy McKenzie's paper for Acoustics Australia in 2012 and in a paper presented at the Institute of Acoustics Autumn Conference in 2015 by Andy along with fellow wind turbine noise specialist Andrew Bullmore. Both of these papers are available in the Publications - Our Published Papers section of this web site.
National Planning Policy Framework
UK Ministry of Housing, Communities and Local Government
The new (2018) NPPF refers to noise at Paragraph 170(e) where it states that:
Planning policies and decisions shoud contribute to and enhance the natural and local environment by preventing new and existing development from contributing to, being put at unacceptable risk from, or being adversely affected by, unacceptable levels of soil, air, water or noise pollution or land instability.
It is considered further in general terms at Paragraph 180 and for minerals extraction at Paragraphs 204 and 205.
ProPG: Planning and Noise
UK Institute of Acoustics
The Professional Practice Guidance on Planning & Noise (ProPG) represents the consolidated view of the UK Institute of Acoustics (IoA), the UK Association of Noise Consultants (ANC) and the Chartered Institute of Environmental Health on effects of noise on new residential development. It is essential reading for planners, developers and, of course, acoustics practitioners and aims to protect home dwellers from noise by putting good acoustic design at the heart of all new residential development.
