Acoustic enclosures installation at an offshore oil field.
Application Details:
Excessive noise from high pressure water pumps was causing problems at an offshore oil field.
SUPPLY SCOPE:
Design, manufacture, supply and installation of a series of bespoke high specification acoustic enclosures to mitigate excessive noise levels, in line with the UK’s Control of Noise at Work Regulations 2005.
PRODUCT SELECTION AND PERFORMANCE:
In order to effectively mitigate noise, a selection of bespoke 316 stainless steel acoustic enclosures were designed and installed on-site. Each enclosure included integrated acoustic louvres for ventilation of the equipment, while maintenance access was granted by folded framework and a high number of access doors. Vision panels and windows were also included in the design.
ACOUSTIC PERFORMANCE:
The high-specification acoustic containers were designed to deliver a nominal noise reduction in line with the client’s requirements.

Application Details:
Acoustic screens for air conditioning and ventilation plant
SUPPLY SCOPE:
Total of 3 no. roof-mounted acoustic screens for the reduction of noise emissions to comply with planning requirements. The screens were supplied complete with supporting steelwork, designed and fabricated by Wakefield Acoustics.
Special Requirements
The screens incorporated personal access doors for plant maintenance. In order to assist with installation due to access issues, the screens were fabricated in large pre-assembled sections, complete with steelwork supports, to aid installation on site.
PRODUCT SELECTION AND PERFORMANCE
The acoustic panels were designed to offer a direct transmission loss of 25dBA.

Application Details:
Acoustic louvres for roof-mounted plant equipment in Covent Garden, London.
SUPPLY SCOPE:
Design, supply and installation of approx. 50m² of acoustic louvres to reduce plant noise at the surrounding buildings to levels specified by the acoustic consultant.
Special Requirements
Due to both acoustic and aesthetic requirements, two types of louvres were required for the project. To meet more stringent noise requirements, bespoke designed 300mm deep chevron acoustic louvres (Type WA-ACL-300DB) were installed, preventing line-of sight through to the plant equipment from below.
A bespoke design single bank inverted acoustic louvre (200mm deep), with an additional weather guard to minimise water ingress, was installed on the face of the surround. Due to a less stringent noise specification on this face of the surround, these louvres were designed to again eliminate line-of-sight through to the plant equipment from below, while minimising the depth of the louvre and the cost for the customer.
PRODUCT SELECTION AND PERFORMANCE
The acoustic louvres were designed to offer significant reductions in noise transmissions.

Acoustic screen installation at Trinity Leeds shopping centre
Application Details:
Acoustic screen installation at Trinity Leeds shopping centre in the heart of the city.
SUPPLY SCOPE:
Design, manufacture, supply and installation of a 35m roof mounted acoustic screen, located to a height 3m above the roof level at Leeds Trinity Shopping Centre, to reduce HVAC plant noise.
Special Requirements
In order to effectively mitigate noise from HVAC plant equipment, a bespoke designed acoustic screen was supplied and installed on the roof of the shopping centre. The high specification screen was supplied with structural support steelwork and access doors. While a polyester powder paint finish was applied to the acoustic panels.
ACOUSTIC PERFORMANCE:
The acoustic screen was designed to offer significant reductions in noise transmissions.

Environmental noise from air conditioning plant equipment at a luxury residential development. The plant was producing excessive noise that was impacting on nearby areas around the development.
SUPPLY SCOPE:
Design, manufacture, supply and installation of a high-specification acoustic louvred door and over panel to reduce noise from air conditioning plant equipment, and the associated environmental noise impact on nearby areas. The installation was also necessary in order to permit airflow to the plant.
Product Selection and Performances:
To efficiently attenuate noise emissions and meet the consultant’s requirements, the bespoke acoustic louvred door and over panel were fitted around the existing air conditioning plant. The integrated louvred door permitted access for plant maintenance.
ACOUSTIC PERFORMANCE:
The acoustic louvred door and over panel were designed to offer significant reductions in noise transmissions, in line with the consultant’s requirements.
