Acoustic Design

Acoustic design is a fundamental part of almost every acoustic consultancy projects.  After a noise measurement survey has been carried out there is usually a need to design mitigation measures to solve a noise problem, or to prevent a future noise problem arising. For some types of buildings acoustic design of room finishes is necessary to enhance internal acoustics.  Getting acoustic design wrong can mean either expensive over provision, or costly remedial works, or ending up with rooms not fit for purpose. 

Environmental Impact Assessment

Noise and vibration is usually one of the environmental issues that needs to be considered for large scale development proposals. The EIA Regulations require a comprehensive Environmental Statement (ES) to accompany a planning application for developments of significant size, scale or that have the potential to cause significant impact. Noise and vibration needs to be considered at the construction and operational stage. Impacts from the operation of the development including the affect of transportation of goods and people to and from the site.

Noise at Work

Exposure to high levels of noise at work can lead to permanent hearing damage for employees. This can lead to prosecution of the employer by the Health and Safety Executive and potentially costly compensation claims from the employees.

Noise Monitoring

Noise monitoring surveys are central to most of the work that is carried out by Hepworth Acoustics. To investigate complaints about noise pollution it is necessary to carry out a noise measurement survey. Also, having an understanding of the existing noise climate is vital in assessing any proposed noise generating development. Noise monitoring is often required to check compliance with noise limits specified in planning conditions.

Research

We have carried out a range of research projects for private companies, local authorities and central government since the early 1990's. The results of these projects have been used to inform central and local government policy, European Union guidance and private business activities.

Vibration Monitoring

A number of projects now require ground vibration assessments to be submitted with a planning application as well as a noise assessment. This is particularly the case for residential applications adjacent to railway lines; mines and quarry developments where blasting will be carried out; and construction projects with impact piling or other vibration generating operations.

Building Services

Building services are a fundamental part of most new and refurbished buildings.  Ventilation and heating/cooling systems have the potential to cause noise issues within the building being served or to adjacent noise sensitive premises.  The principles of noise control for building services are well understood, and noise emision data is available for most types of building services equipment. However, we are commissioned to work on a large number of noise issues caused because noise and vibration issues have not been adequately considered at the design and installation stages.

Expert Witness

Public inquiries and court cases are becoming increasingly common experiences for many businesses.  The figures for 2011/12 show that approximately 18% of planning applications in England were refused. There weare around 16,500 appeals, approximately 20% of the number of applications refused. However the success rate for appeals in this period was only about 33%.

Noise Mapping

Computerised noise contour mapping is a powerful tool that can be used to investigate environmental noise levels and the effect of mitigation measures for a wide range of sources.  It can be used for a single item of plant up to whole cities. Hepworth Acoustics has been involved with noise contour mapping for over 10 years and uses a variety of noise mapping tools to provide relevant noise data.  The company is at the forefront of developing expertise and methodologies to deliver accurate results, and has carried out research work for Defra and WG-AEN on noise mapping accuracies.

Planning & Licensing

Many projects now require environmental noise assessments to be submitted with a planning application. Some local authorities will not register planning applications until a noise report has been submitted. The need for noise assessments stretches from the largest infrastructure projects down to plannin applications for a single item of external plant. In addition to planning requirements, licensed premises will often require a noise report to obtain a licence, or extended trading hours, from the local authority.

Sound Insulation Testing

Changes to the Building Regulations for England and Wales that were introduced in 2003, mean that new and converted residential developments must comply with stringent sound insulation requirements.  The changes introduced a requirement for approved test bodies to carry out pre-completion testing (PCT) of actual sound insulation performance between dwellings in some new build developments and and in all converted buildings.
