ICR’s experience in automotive acoustics ranges from conducting experimental studies of noise and vibration transmission pathways to developing theoretical models for forecasting traffic noise. At the same time, ICR develops new test procedures optimizing the current methods of vehicle characterization both in time and money.


Working procedure

The realization of high-tech projects in this sector has allowed us to develop our own methodology for measuring noise and vibrations and to propose efficient solutions to the problems of noise and vibrations posed by customers.


Some of the services offered are:
Advanced transfer path analysis (TPA and ATPA) of noise and vibrations.
-Vibro-acoustic contribution of each element of the passenger compartment to the level received by the driver.
For the reconstruction of internal noise in the medium to high frequency bands.
-Custom software for vibroacoustic analysis of a problem.
-Quality control.
-Custom design of silencers and acoustic solutions.
-Numerical simulations (FEM, BEM, CFD).
