INTAC is a multifunctional tool box for acoustic and vibratory measurements. This analyzer operates with National Instruments acquisition materials and performs standard measurements (FFT, stepped sine, time domain measurements), intensity probe measurements, reverberation time measurements or dual microphone duct measurements.



Maine 3A is dedicated to calculating the acoustic performances of multilayer materials (absorption, transmission, unique indicators for diffuse fields, etc.). It uses the method of transfer matrices and integrates most of the standard models describing poroelastic and viscoelastic materials.
