Testing and Assessment

Helping you to comply with national standards and regulation.

Acoustic Privacy

Assess and improve the degree of acoustic privacy to protect acoustically sensitive areas.

Noise At Work

Understand how to protect employees from noise within their place of work.

Sound Insulation

For the purpose of investigation, or to demonstrate compliance with Approved Document E.

Acoustic testing and noise assessments are a key part of understanding the performance of a space. It also a factor in demonstrating compliance with national standards, or regulation.

At Completely Sound Limited we offer a range of sound testing services. See below for example services, click to learn more, or get in contact to understand how we may be able to help.

Example Testing and Assessment Services Below.

The most recent, and current, assessment procedure for field tests of both airborne and impact sound insulation can be found within BS EN ISO 16283:2014. This set of standards is divided into 3 parts and covers airborne sound insulation, impact sound insulation, and façade sound insulation.

A sound insulation test will be required in order to meet the minimum acoustic standards set by the UK building regulations. A sound test that shows separating partitions are in line with the figures within approved document E will have no problems when reviewed by building control.

Consultants at Completely Sound Limited have a large amount of experience in this area of acoustic testing. Get in touch to discuss how we may be able to help.

Sound Insulation Testing


The Control of Noise at Work Regulations 2005 came into force for all industry sectors in Great Britain on 6 April 2006, 2 years prior to enforcement within the music and entertainment sectors. The aim of the Regulations is to ensure that workers’ hearing is protected from excessive noise at their place of work. It has been demonstrated that excessive exposure to high noise levels will increase the prevalence of hearing loss and/or tinnitus.

As a specialist consultancy Completely Sound Limited has both the equipment and expertise to ensure that an employer is fully aware of their legal requirements. We can also provide best practice advice and guidance on how to achieve a working environment in line with the requirements of relevant legislation.   

There are often situations in which acoustic privacy should be considered. In situations where sound insulation between rooms is considered, the need for adequate privacy should be assessed. For example, is there a requirement for speech in one room to be unintelligible, or even completely inaudible in the other? This may be the case in commercial buildings between executive, and open plan offices for example. The concept of acoustic privacy will depend on a few factors. One of these will be the sound insulation performance of the common partition. Another will be the background noise level, and also the sensitivity of people within the receiving room.

In order to fully understand the level of privacy that would be suitable in your situation, and for any advice on testing or improving this level, feel free to get in touch.

Reverberation Time Measurements

Reverberation time is a very important metric to think about when designing any space used for speech or music. Being able to hear speech clearly, or appreciate music fully, if often a result of a suitable reverberation time. Acoustic testing to establish the reverberation time within a room requires specialist equipment. However, the process of completing this test can be simple, and often remedial work to fix large amounts of reverberation are inexpensive and products simple to install.
