Powerful Room Acoustics Parameter Calculations Room Acoustics Parameter Calculations for WinMLS As a room acoustician you can with this product perform your standard acoustical measurements very user friendly, with high quality and at low cost. The powerful measuring method is used by professional acousticans. Measure the impulse responses of rooms, and calculate the room acoustical parameters. All you need, in addition to your normal set of transducers and amplifiers, is a PC and an inexpensive standard sound card (not all sound cards are suitable, we provide a list of tested sound cards). The current version of the module calculates parameters according to the recently revised ISO 3382 standard: Reverberation time, early decay time, early-to-late indices, definition, and centre time. Strength, speech transmission index and two channel options like lateral fraction are also provided. In addition, the new parameter late lateral strength is included. Inter-aural crosscorrelation will be implemented in a future version. Noise detection and compensation is included for all parameters and the calculations are tested against international benchmarks. The toolbox is being developed by dr. Johan L. Nielsen, who has for several years been working with room acoustics both at the Norwegian Institute of Technology and at the University of Auckland, New Zealand. He has published papers on measurement techniques and accuracy of room acoustical parameters. He is currently development manager at Silence International AS, in Oslo, Norway. Price: $79
