We provide assistance with resource consents, building consents and produce acoustic certificates. Being designers, problem solvers, advisors, mediators and inventors, we practise across a wide range of specialities, this includes but is not limited to room acoustics and noise reduction. Our room measurements enable our clients to convert their premises into pleasant surroundings where customers as well as staff feel undisturbed. The acoustical ‘atmosphere’ of a room is as important as the visual atmosphere if not more and can determine whether people are comfortable or not. The acoustics of a room is also very important for the aural intelligibilty and ambience.


Our clients are businesses and organisations, including government organisations, as well as private people. They are mostly local but we also offer services nationwide. We develop solutions to real life problems affecting individuals, businesses, institutions, and the community. Our services are tailored to our customers' needs and expectations with the objective to help clients achieve their visions in acoustics by assisting with projects from planning and conception, through design, construction and evaluation.
