Transportation noise is the most widespread source of noise throughout the UK and is still increasing year on year. Noise from road, rail and aircraft is not only an issue when designing new infrastructure projects, but is also a major consideration when building noise sensitive properties such as housing and schools.
Hepworth Acoustics has considerable experience of assessing the noise impact of new road, rail and airport schemes, both for the construction and operational phases. The projects have included work for environmental statements, public liaison meetings, providing expert evidence at public inquiries and monitoring noise from construction and operation.
The company has a wide range of noise prediction software to allow the assessment and design of mitigation measures for all forms of transportation noise. All assessments will be carried out to appropriate central government guidance including Design Manual for Roads and Bridges (DMRB) and Transport Analysis Guidance (TAG).
Many new developments are located adjacent to existing transportation noise sources, particularly with the desire of government to encourage the re-use of brownfield and city centre sites. Local authorities will generally require an assessment of existing noise levels prior to determining planning applications for noise sensitive developments. Hepworth Acoustics has experience of many of these assessments across the UK and will recommend cost effective mitigation measures to meet the requirements of the local authority and Planning Policy Guidance 24 Planning and Noise.
The company also has considerable experience of producing the transportation noise maps required under the Environmental Noise Directive produced by the European Union. The first round of noise maps have been produced and published in the UK and we are able to provide guidance on Noise Action Plans which are also required by the EU Directive .
