Noise Impact Assessment

The introduction of new industrial or commercial equipment generally falls under the scope of BS 4142. This could be the installation of relatively small devices such as air conditioning systems, or the development of large commercial or industrial premises.

To ensure compliance with this standard, BS 4142 requires a noise impact assessment to be conducted to understand the potential impact caused by the proposed equipment or development upon the local environment.

It is common during the planning application process for local authorities to request a noise impact assessment report to discharge any concerns relating to noise. This is required to provide assurance that no adverse acoustic impact will result from the proposed equipment or development or to provide an early indication that the impact will be significant and corrective measures should be considered.

NCSL delivers comprehensive Noise Impact Assessment to our clients in order to minimise issues during the planning application process.

Where a noise concern is identified by an impact assessment report, we provide advice to our clinets regarding corrective measures to prevent any disturbance in the local environment and to achieve a successful outcome in the planning process.

Due to our forward thinking business structure, we are able to offer noise impact assessments to our clients at extremely competitive prices, and we endevour to match or beat any like-for-like quotation.

Acoustic Design Reviews

For clients involved in the development of industrial, commercial or residential properties, our design review service provides support to ensure noise legislation conformity.

Our review service can be used to focus on the noise reduction of partitions, such as walls or floors, or to optimise the layout of developments to minimise acoustic disturbance.

Acoustic performance optimisation at the design stage of a project is significantly more cost-effective compared to the installation of corrective measures which may be required to meet regulations once the project is fully developed.

In particular, we specialise in acoustic reviews for:

  • Approved Document E (Part E – Resistance to the passage of sound).
  • Sound Insulation Testing
  • Robust Details
  • Building Bulleting 93 (BB93 – Acoustic Design of Schools)
  • BS 8233 (Sound insulation and noise reduction for buildings – Code of Practice

Noise & Vibration Control

Thanks to NCSL’s experience in acoustics and noise control engineering, we are able to provide noise control solutions to clients across a wide range of industries and applications.

This may be required to protect the hearing of employees, mitigate noise break-out to local communities or to simply improve the acoustic environment within workplaces.

Our acoustic consultants are also highly experienced in the assessment and control of vibration.

Whatever your requirements, NCSL can provide effective and innovative noise and vibration control measures to suit your needs.

Echo and Reverberation Control

Excessive echos and reverberation can pose significant challenges for speech intelligibility, communication systems and high fidelity audio reproduction.

In particular, acoustic environments for education, sport and music events tend to suffer due to their large size, hard boundary surfaces and symmetric geometries. This is also true of open plan offices and call centres, which can also suffer from poor acoustics, leading to communication difficulties.

NCSL can provide consultancy services to assess and optimise existing spaces for acoustic performance, whilst also providing specifications to ensure proposed spaces are designed correctly.

At NCSL, we have over a decade of experience in reverberation assessment and control over a wide range of applications and venues.

Bespoke Projects

At NCSL, we know that not all acoustic projects are covered by governing standards. In these cases, our vast expereince allow us to work closely with clients to develop bespoke methods of assessment and optimisation.

This is generally a requirement for our clients in the fields of product development, however we are able to assist our customers any bespoke projects which require noise & vibration support.

NCSL experts supply consultancy services in many fields of acoustics, including:

  • Environmental noise
  • Building acoustics
  • Laboratory acoustics
  • Hearing protection
  • Sound power assessment
  • Industrial noise
  • Noise at work
  • Vibration control
  • Loudspeaker design
  • Room acoustics

This provides NCSL with a solid foundation of knowledge to provide expert consultancy to our clients throughout all fields of acoustics.

Sound Insulation Testing

NCSL offer a wealth of experience in building acoustics projects, particulatly in terms of sound insulation testing (also commonly refered to as sound testing, pre-completion testing or Approved Document E testing).

Newly built or converted properties for residential use are required to meet specified sound insulation requirements relating to separating wall and floor structures as per Approved Document E.

This involves the measurement of a noise source on either sound of a partition (the wall or floor in questions) and the application of corrections for reverberation time and background sound to assess the noise reduction provided by the structure.

In addition, where floors are to be assessed, an impact test is also conducted.

NCSL acoustic design review services can help developers to understand the likelyhood of passing the sound insulation test before construction begins, in order to minimise expensive corrective works once the seperating walls and floors have been built.

NCSL also offer sound insulation sample testing, in order to define the peformance of party walls or floors on an individual basis before a design is implemented across a full development of dwellings.

In cases where a partition fails this assessment, NCSL can provide remedial advice to correct the issue and re-test when required. In addition, NCSL can review proposed constructions in order to highlight any concern areas before work commences.

Due to our forward thinking business structure, we are able to offer sound insulation testing to our clients at extremely competitive prices, and we endevour to match or beat any like-for-like quotation.
