A system for measuring acoustic properties of rooms using Dirac platform and I/O unit with two input and two output channels with phase synchronization, which ensures accuracy and repeatability of the measurement. The system allows the measurement of room acoustics according to ISO 3382 and measurement of speech intelligibility in accordance with IEC 60268-16 using an internal or an external MLS generator, linearly and exponentially swept harmonic signal, noise and impulse signal. The system includes two measurement microphones, head and torso simulator and omnidirectional sound source with amplifier.
