• Performance of Acoustic products like noise barrier, absorber, trims, enclosure etc.
• Optimization of Sound Package materials for noise and vibration control
• Meet Noise level Targets  with optimized noise control treatments and related weight
• Prediction of Elastic Properties of the Tires to evaluate the Rolling Noise

Topic: Diffuse field absorption and transmission loss measurement combine with NOVA for an optimal material design

• The difference between the impedance tube measurement and the diffuse field measurement
• Model a diffuse field behavior in NOVA based on the properties extracted form a normal incidence measurement
• Acoustic test cabin measurement overview of the hardware and comparison with NOVA simulation
• Transmission loss measurement test using Mecanum test cabin and a full-size facility.

On Demand Workshop Topics:
