About Us

A Service Company

We aim to be at the forefront of acoustics consultancy firms, with a strong sense of commitment to our clients and their projects.

We are a medium-sized independent consultancy that is large enough to handle the most complex projects, yet small enough to respond flexibly to client needs and allows our clients the reassurance of knowing the consultants working on their projects.

We work in a wide variety of sectors but are primarily known for our work related to the planning process, construction, utilities and entertainment industries. We work throughout the UK and occasionally further afield – a map showing the location of completed projects can be seen below.

History

The seeds of the company were sown in 1992 when Patrick Allen, who was then Head of Architectural Acoustics at a leading UK consultancy, started an audio production company. We have expanded our areas of expertise over the years, but are still, we believe, unique in providing professional audio production facilities in addition to the more usual acoustic services.

Our people

Our consultants are qualified to at least first degree level in acoustics-related subjects, and are members of the relevant professional institutes for their specialist areas. We back up technical knowledge with practical experience and a pragmatic outlook on solving real-world acoustic problems. We are supported by state of the art instrumentation and computer modelling facilities.
