Webinar 1 - Characterization & Modeling of Acoustic Materials
Date: March 25th Time: 3:30PM (IST) Length: 1h
Over the few decades, the characterization of Porous Sound Absorbing Materials has been of increasing interest to both the acoustic engineers, material suppliers and OEMs. It is particularly important that acoustic engineers are able to predict the Acoustic Properties (BIOT Properties) of these materials, to get a quantitative measure of the acoustic energy absorption and transmission loss also.
This webinar presents the Experimental & Numerical methods help to predict the BIOT properties, Which provide the link between the Acoustic properties and its NVH performance in various Industrial Segments.
Key Takeaways:
- Acoustic Materials characterization using Physical Testing / Simulation / Combined methods
- 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
