The Independent Noise Working Group (INWG), formed during August 2014, is a multi-disciplinary team fully independent of the wind industry supply chain with expertise or access to expertise including acoustics, environmental health (LPA), health & sleep, legal & planning, physics, meteorology, statistics & data analysis. The INWG was jointly sponsored by Chris Heaton-Harris MP (Conservative, Daventry) and the National Alliance of Wind Action Groups (NAWAG).
The objective of the INWG at that time was to conduct an independent and scientific study into wind turbine noise amplitude modulation (AM) that is able to credibly challenge the methodologies and findings of the Institute of Acoustics sponsored AM study. The INWG AM study was presented to Government at Westminster on 13 October 2015 and at the Institute of Acoustics conference at Harrogate on 15 October 2015.
The INWG steering committee originally consisted of:
Richard Cowen, LLB: Solicitor (retired) specialising in planning then criminal law. Has been actively involved with NAWAG on legal issues including noise and the Den Brook judgment.
Richard Cox: Electrical engineer (retired) with a career in the power generation industry.

Bev Gray: Company Director (retired) Battery back-up DC power supplies for electricity generation and distribution companies, rail, communication and utility industries.
Melvin Grosvenor: Consultant supporting rural communities with wind turbine proposals. Senior Management & Regulated Finance experience.
