    Sound Space Design (UK)

    Consultants and designers in the acoustics of concert halls, theatres, interesting spaces and soundscapes of all kinds.  We bring to our design work the experience and technical means to put you in an environment before it is built – to let you hear what a hall will sound like before it is built, or even completely designed.  For over 25 years Essert has been leading the development and application of  physics and psychoacoustics modelling to the building design process, and honed the modelling process for accuracy and relevance.  Recently the SSD team have been developing greater accuracy and cost effectiveness and a more streamlined links to design.  CATT-Acoustic is an important part of our system, working  as a front end that drives our quick-to-apply auralisation in our SoundSpace studio and enables us to sketch with sound.
