DIRAC Room Acoustics Software - Type 7841
Measuring Room Acoustics
Brüel & Kjær is the sole worldwide distributor of DIRAC, an acoustics measurement software tool, developed by Acoustics Engineering.
DIRAC Room Acoustics Software Type 7841 is used for measuring a wide range of room acoustical parameters. Based on the measurement and analysis of impulse responses, DIRAC supports a variety of measurement configurations.
For accurate measurements according to the ISO 3382 standard, you can use internally or externally generated stimulus signals through a loudspeaker sound source. Survey measurements are easily carried out using a small impulsive sound source, such as a blank pistol or even a balloon.
Speech 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.
DIRAC is not only a valuable tool for field and laboratory acoustics engineers, but also for researchers and educational institutions.
