Noise Impact Assessment

Noise Impact Assessments are required when new industrial or commercial equipment falls under the scope of BS 4142. This could be the installation of small devices such as AC systems, or large commercial / industrial premises.

BS 4142 & Planning

To comply with this standard, BS 4142 requires a noise impact assessment. This helps to understand the impact which may be caused by the equipment or development on the local environment.

Usually, during the planning application process, local authorities will request a noise impact assessment report to discharge any concerns relating to noise. This provides confidence that no adverse acoustic impact will be caused by the proposed equipment or development. In some cases, a noise impact assessment will also provide an early indication of a negative effect – so that corrective measures can be used.

Noise Impact Assessment

Noise Impact Assessment

NCSL provides Noise Impact Assessments to our clients to reduce issues during the planning application process.

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

Competitive Prices

Because of our forward-thinking business structure, we can offer noise impact assessments to our clients at extremely competitive prices. We also endeavour to match or beat any like-for-like quotation.

Sound Insulation Testing

NCSL have years of experience in building acoustics. Particularly in terms of sound insulation testing (also known to as sound testing, pre-completion testing or Approved Document E testing). This involves the testing of separating floors and walls.

This is needed for newly built or converted properties for residential use. The results must meet specified sound insulation requirements as per Approved Document E.

How is the sound test done?

This involves the measurement of a noise source on either sound of a partition (the wall or floor in questions). Corrections are applied for echoes and background sound to normalise results. In addition, where floors are to be assessed, an impact test is also conducted. All of our sound tests are accredited by SITMA.

Sample Testing & Design Reviews

NCSL acoustic design review services can help developers to understand the likelihood of passing the sound insulation test before construction begins. This helps to minimise expensive corrective works once the development is complete.

NCSL also offer sound insulation sample testing. This allows us to define the performance of party walls or floors on an individual basis before a design is implemented across a full development.

In cases where a partition fails this assessment, NCSL can provide remedial advice. The problem can then be corrected, and the partition is re-tested. In addition, NCSL can review proposed constructions in order to highlight any concern areas before work commences.

When to Test?

Testing can be done when: All walls and floors are complete. Internal and External doors are fitted. Windows are fitted. Sockets are fitted and sealed. 240v power is present on site.

Competitive Prices

We offer sound insulation tests to our clients at extremely competitive prices. We also endeavour to match or beat any like-for-like quotation.

Acoustic Design Reviews

NCSL offer a design review service to help noise legislation conformity and good acoustic performance. This is useful for clients involved in the development of industrial, commercial, or residential properties.

This review service can be used to focus on the noise reduction of walls or floors, to help with sound insulation testing. It can also be used to optimise the layout of developments to aid noise control.

We also conduct reviews and surveys to BS 8233. To help ensure that properties meet acoustic performance targets.

Acoustic performance optimisation at the design stage of a project is much more cost-effective compared to post completion. This is due to the extra cost of installation of corrective measures requiring existing structures to be removed.

We specialise in acoustic reviews for:

  • Approved Document E (Part E – Resistance to the passage of sound).
  • Sound Insulation Testing.
  • BS 4142 Noise Impact Assessment
  • Robust Details.
  • Building Bulleting 93 (BB93 – Acoustic Design of Schools).
  • BS 8233 (Sound insulation and noise reduction for buildings – Code of Practice.
  • Bespoke Projects.

Noise & Vibration Control

NCSL have years of experience in vibration & noise control engineering. Due to this, we can provide noise and vibration control solutions to clients from a range of industries and sectors.

This can protect the hearing of employees, reduce noise break-out to local areas and improve the acoustic environment within workplaces.

NCSL also offer vibration condition monitoring services. This is used to check the health of machinery over time – using vibration analysis.

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

No matter your requirements, NCSL will provide effective and innovative noise and vibration control measures to suit your needs.

Echo and Reverberation Control

Echoes and can pose big challenges for understanding speech within rooms. Lots of echoes in the same space causes reverberation (the effect you hear in a large hall or church). This causes issues for speech intelligibility, communications, PA systems and hi-fi audio.

Reverberation Control

Acoustic spaces for education, sport and music events tend to suffer most. This is due to their large size, hard walls and floors, and their square shape. This is also true of open plan offices and call centres, which also suffer from poor acoustics, leading to communication issues.

NCSL provide acoustic consultancy services to assess and optimise reverberation in existing spaces. We also provide specifications to ensure proposed spaces are designed correctly.

At NCSL, we have over a 15 years of experience in reverberation testing 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 experience allows 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 can assist our customers with any bespoke projects which require noise & vibration support.
