First the geometric data for the room is entered,then data for the acoustic absorption of the materials that are on the walls and other surfaces. From this, reverberation times and other acoustic parameters can be computed, and the model can be used to test various modifications that might be made to the acoustics.Next, loudspeakers can be added to the model at various locations. Data for the 3D frequency response is provided by loudspeaker manufacturers, and is part of the EASE database.

With this data, a complex impulse response can be computed from any loudspeaker or system of loudspeakers to any point in the room. In addition, the response of the system can be computed for a grid of points of interest (for example, audience seating and a stage). It is thus easy to study the uniformity of distribution of sound over the listening area, as well as how much sound returns to the stage. And since the acoustics of the space have been computed, predictions of speech intelligibility can be mapped as well.

Room acoustics prediction, in general, is the process where, using geometrical acoustics, octave-band echograms are predicted based on a 3D CAD model of a room. First the geometric data for the room is entered, then data for the acoustic absorption of the materials that are on the walls and other surfaces. From this, reverberation times and other acoustic parameters can be computed, and the model can be used to test various modifications that might be made to the acoustics.

The A/V Team are experts in all areas of noise control and limitation. We conduct surveys to examine noise levels and can give advise on all statutory provisions in relation to noise levels for both staff and the public. We can offer customers detailed proposals for new and existing structures and we also supply a large range of audio limiting equipment to deal with noise problems. The A/V Team provides expert witness reports for Licensing and Planning Applications in relation to proposed and existing premises, including attendance at Court. We cover: Sound Systems for Live Events Court Licensing Applications Building/Structural Noise Consulting Noise-Constrained Conditional Planning Permission Employee Exposure Levels and Hearing Protection Programmes Noise Measurement and Site Surveys Noise Predictions and Noise Control Measures Noise Control Materials. The A/V Team gives you control!
