Common Directional Loudspeaker for Impulse Response Measurements", Appl. Issue 6 pp. Many thanks Speech intelligibility measurements can be carried out in compliance with the IEC 60268-16 standard, for male and female voices, through an artificial mouth-directional loudspeaker sound source or through direct injection into a sound system, taking into account the impact of background noise. The Echo delivers a calibrated signal that is used by DIRAC to calculate different speech intelligibility parameters. Time domain views: original impulse response and Energy-Time Curve from a single-channel measurement, Time domain views: comparing two single-channel impulse responses and their Forward Integration Curves, Frequency domain views: linear FFT and phase spectra. to those who have already donated, your generosity keeps REW development going and is greatly Architectural acoustics is more complicated than it … ARTA software consists of following programs: ARTA - program for the impulse response measurement and for real-time spectrum analysis and frequency response measurements. Users can compare the acoustics of one room with another, validate sound systems and perform scale model measurements. PDF copy (11.8MB, courtesy of Steve Bolser).
