Project Information

A regional 2015 RIBA award winner with a mix of retail and cellular and open plan offices, this project required considerable acoustic input for controlling reverberation time, noise ingress from natural ventilation and sound insulation of the CLT and steel frame structure.

Project Information

The main focus was to develop the natural ventilation strategy for the project, while consideration of the high external noise levels from the main road.   Detailed noise map modelling was employed to accurately estimate noise levels at each façade, whilst on-site testing of the sound reduction across the existing open windows was used to determine the extent of louvres required.

In addition, extensive acoustic modelling of the many interlinked open plan offices was undertaken to provide to the client effective methods of improving the acoustic environment within such spaces.

Our Services

• External noise surveys with façade noise break in assessment and noise break out assessment from plant for planning.
• Detailed internal sound insulation design.
• Detailed reverberation assessment of cellular, atria and open plan spaces.

Reviewing the reduction of speech intelligibility over distance was an effective method in demonstrating to the client the various benefits particular types and placements of acoustic treatment.  A detailed study of the activities and noise sources in each area allowed MACH to demonstrate to the client the benefits of acoustic treatment to control noise between spaces, both visually and by audio.

We produced a number of reports on the project with a high graphical content, that we make available on our website to download as example reports.
