How do I pass a Sound Test?



Performance in builds varies for many reasons. Assuming correct designs and material selection, the most common factor influencing performance is poor workmanship. Detailing is critical to maximising on site performance, especially in floor isolation and appropriate party wall construction.

Soundguard Acoustics recommend that you appoint our expert acoustic consultants at the start of your project to review the designs, and then also to carry out on site inspections during the build process to check specifically for any workmanship issues that could cause problems when it comes to sound testing. Soundguard Acoustics can provide routine review of basic plans to complex computer modelled partition designs to predict the completed performance.

 If you would like Soundguard Acoustics to review your designs and proposals or to comment on their suitability, then please speak to us about our acoustic design advice service. This is a relatively inexpensive option that can avoid sound testing failures which result in expensive remedial treatment and delay in your project.

What do I do if the test fails?

In line with the regulations you are required to carry out remedial works to ensure the development meets the relevant performance requirements and re-test. If you don't know what to do by way of remedial works then Soundguard Acoustics can advise you. You may also be asked by Building Control to test further examples of the construction elsewhere on the development in order to restore confidence and/or highlight the extent of the problem.


What are Robust Details?



From the 1st July 2004, and for new house and flat developments, Robust Details may be used to eliminate the need for end of build pre-completion testing. Robust Details are high performance constructions that are capable of providing consistently good sound insulation but do require that the design is registered with, and approved by, Robust Details Ltd (RDL) and that confirmation of the construction, through on-site visual inspection by RDL has been completed in accordance with the registered design.

The specific details in the RDL handbook must be followed explicitly and each plot formally 'registered' with RDL before building commences. Robust Details registration cannot be used in conversions and so pre-completion testing must be undertaken in these circumstances. 

As the specific details in the Robust Details scheme may not allow for flexibility in the design of a development or may not prove cost effective, pre-completion testing may still prove a more suitable and effective route to demonstrate compliance.

Garage noise can be peaceful

This month Soundguard Acoustics Ltd has been involved with two garage planning applications. General vehicle maintenance and body work repair is associated with noise and residents may understandably raise concern when these businesses relocate nearby. In both instances a BS4142 assessment was undertaken to establish the likely noise impact. Where a noise impact was possible then noise control techniques were applied and included an extraction exhaust silencer for a paint booth and additional internal wall and roof treatments for the building. A sound solution that satisfied planning, the local residents and the expanding businesses.

Noise control in an animal feed mill

Harpers Home Mix is located in Holsworthy, Devon. They requested that South West Noise Consultants Soundguard Acoustics Ltd assisted them in meeting their Control of Noise at Work obligations for their staff. The Company had already created a good noise control policy and had made some initial noise measurements. The professional input of Soundguard Acoustics Ltd assisted them in completeing their Noise at Work Risk Assessment, identifying noise sources and providing an action plan of noise control.

Holiday Retreat Centre sounds just right

South West based acoustic consultants Soundguard Acoustics Ltd were invited to Lee Abbey, Lynton, Devon. The Abbey is home to a Christian Community and hosts conference facilities, provides retreat and a holiday centre. Renovations to the main dining hall are planned to expose the original features of this marvelous building but revbereration and noise control was a worry. Soundguard Acoustics Ltd is working with the Abbey to provide an aesthetic solution within their budget to ensure that the dining hall sounds just right.

Sending Residents Barking Mad!

Soundguard Acoustics Ltd was contracted by residents that were unfortunately subjected to continuous Kennel Noise following the inappropriate conversion of neighbouing farm buildings into a Commercial Kennel venture. The noise was seriously affecting their enjoyment of their property and gardens and Soundguard Acoustics Ltd proved this to be the case. Despite the Kennel Owners having their own independent noise assessment we proved that complaints were likely. The Local Authority planning commitee determined that a nuisance existed and a 17 vote to 1 support was given to our report and for the removal of the Kennels. Needless to say that our client was delighted!

Baker v Quantum Clothing - Hearing Damage in Industry

This appeal concerned the liability of the appellant employers in the knitting industry of Derbyshire and Nottinghamshire for hearing loss suffered by employees prior to 1 January 1990. The central issue was whether liability existed at common law in negligence and/or under the Factories Act 1961, s 29(1) towards an employee who suffered noise-induced hearing loss due to exposure to noise levels between 85 and 90dB(A)lepd.

The Supreme Court allowed the appeal by a majority of 3:2 and restores the judge’s decision at first instance. The court found that the 1972 Code of Practice published by the Department of Employment, which recommended a noise exposure limit of 90dB(A)lepd, constituted an acceptable standard for average employers to adhere to during the 1970s and 1980s. The Court also endorsed a further two year period beyond 1988 allowed by the judge for implementing protective measures, thus meaning that the average employer had no common law liability before 1 January 1990. Additionally, the Factories Act 1961, s 29 did not impose a more stringent liability than at common law. The employers by complying with the Code of Practice were not in breach of the statutory duty before like dates as those from which they were potentially liable at common law. [article]

Barking about Noise Control

South West Acoustic Consultants Soundguard Acoustics were involved with the introduction of an innovative Parasol Kennel design at a new Animal Rescue Centre in Devon. As the site was in the planning stages then noise measurement at a similar location in Plymouth, Devon was used to collate data that could be used in the planning report. The design of Parasol kennels helps to reduce the barking noise of dogs by restricting their field of view, by introducing sound absorbing material into the design and avoiding long lines of barking dogs as typical of a linear barrack style kennel. Planning & noise experts Soundguard Acoustics continues to work with the developer, planners and the kennel designer to determine the best noise control solutions for the project.

A ray of Sunlight in Noise Risk Assessment

Soundguard Acoustics Consultants, Devon were asked to repeat Workplace Noise Risk Assesssments for both the Honiton, Devon and the Newton Abbot, Devon sites of Sunlight Ltd.

The finer art of sound assessment

Acoustic consultancy is often carried out in heavy industry, at exhaust outlets, in damp fields, during night-time hours on development grounds and building sites. So when South West Acoustic Consultancy Soundguard Acoustics was asked for sound assessment advice at Exeter Rougemont Castle we jumped at the chance. Named Rougemont, after the reddish volcanic rocks on which it stands, the imposing building has changed considerablely since it was built by William the Conquerer in 1068. The castle was seized by Henry III in 1232, visited by Richard III in 1413 and ceased to be a military fortress in 1646. Much of the original building is now absent. What remains is the original structure of the Devon County Court from 1774 and the Castle has now past into private hands and is being renovated for accomodation and events. Devon Acoustic Consultancy Soundguard Acoustics was tasked with providing assessment and noise control advice for the function rooms and accomodation at the Castle.

Noise assessment - it's just nuts!

Parnell Lang, Copplestone Exeter requested the assistance of South West acoustic consultants Soundguard Acoustics to update their Noise at Work Risk Assessments. Parnell Lang is an agricultural mill that mixes bird seed products, machinery consists of mixing silos, conveyors, seed cleaners and packing equipment. Soundguard Acoustics, Bideford, Devon undertook work at the site just over two years ago and the Action Plan of noise control has since been introduced. The Exeter based firm has reduced noise exposure across the site and Soundguard Acoustics was able to assist in assigning revised hearing protection zones and further noise control advice.

Torpedo launch sound testing


Devon based marine engineering firm J+S Ltd requested that South West Noise Consultants Soundguard Acoustics Ltd determine the level of noise risk to employees during their Magazine Torpedo Launch System testing. The torpedos are launched and fired along an internal track within the test bay using compressed air producing peak noise levels as high as 144dBC.

After a noise report of the torpedo system within the development bay was completed the Ministry of Defence requested the test to be repeated on board HMS Northumberland a type 23 Frigate. Sound Level Meters were set up to capture the firing of the torpedo within the weapons room and crew were fitted with DoseBadges and stood at their specific locations to determine their exposure.

It was recognised that in factory and training environments the Control of Noise at Work Regulations 2005 do apply and appropriate control by compressor noise reduction, hearing protection, demarked zones and clear signs was determined to be the most effective approach in reducing the noise exposure of staff and crew. Devon based noise consultants Soundguard Acoustics Ltd continues to work with the company.
