Sound Insulation Testing

We are experts in building acoustics. Particularly in 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.

We conduct this testing 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?

We conduct measurements of a noise source on either sound of a partition (the wall or floor in questions). We then apply corrections for echoes and background sound. In addition, where separating floors are present, we also conduct an impact test. All of our sound tests are SITMA accredited.

Sample Testing & Design Reviews.

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

We also offer sound insulation sample testing. This defines the performance of party walls or floors on an individual basis before implementation of a design across a full development.

When a partition fails this assessment, we provide remedial advice. A re-test follows the partition modifications. In addition, NCSL review proposed constructions in order to highlight any concern areas before work commences.

When to Test?

Testing can start when: All walls and floors are complete. Internal and External doors fitted. Windows fitted. Sockets 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.

Contact NCSL for more information on sound insulation testing.

You can also have a look at the information provided by the GOV.UK website relating to acoustic testing. We also have a blog post on sound testing which you may find useful.

Noise Impact Assessment

Noise Impact Assessments are required when new equipment or developments fall under the scope of BS4142. This could be small devices such as AC systems, or large premises.

BS4142 & Planning

To comply with this standard, BS4142 requires a noise impact assessment. This defines the impact due to the equipment or development on the local environment.

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 provide an early indication of a negative effect – allowing for the installation of corrective measures.

Noise Impact Assessment

Noise Impact Assessment

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

When a noise concern is identified by an impact assessment report, we provide corrective solutions to our clients. This helps to prevent any disturbance in the local environment and to achieve a successful outcome in the planning process.

Competitive Prices

We offer noise impact assessments to our clients at extremely competitive prices. We also endeavour to match or beat any like-for-like quotation.

Contact NCSL for more information on noise surveys & impact assessments.

Further info from the GOV.UK website relating to environmental noise is available here. Info on noise surveys and management can be found here. There is also a blog post on the topic of noise monitoring & impact assessments.

Acoustic Design Reviews

Our design reviews ensure legal compliance and good acoustic performance. This is useful for clients involved in industrial, commercial, or domestic properties.

The review service focuses on the noise reduction of walls or floors, to help with sound insulation testing. It is also used to optimise the layout of sites to aid noise control.

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

Acoustic performance review at the design stage of a project is much more cost-effective compared to post completion. This is due to the extra cost of fitting of corrective measures and the removal of existing structures.

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 are specialists in vibration & noise control engineering. As a result, we 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 monitors 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 can 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 reverb (the effect you hear in a large hall or church). This causes issues for speech, 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 echo in existing spaces. We also provide specifications to ensure correct designed of proposed spaces.

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

We know that not all acoustic projects have governing standards. So, our vast experience allows us to work closely with clients to develop bespoke methods of assessment.

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.
