Noise Vibration Harshness (NVH)

Industry standard software methods like Finite Element Analysis and Statistical Energy Analysis are used for Noise Vibration Harshness (NVH) investigations. With AutoSEA, an award winning software program designed by Vibro-Acoustic Sciences, vibration and noise reduction in design has been made effective and efficient. AutoSEA, a fully graphical, object-oriented implementation of Statistical Energy Analysis, enables Vipac’s engineers to integrate noise and vibration predictions into the design process whilst working closely with existing noise and vibration test processes.

Vipac can provide diagnosis and in-depth analysis of your product’s noise and vibration characteristics. Noise Vibration Harshness (NVH) investigations are conducted using AutoSEA, the award winning CAE-software for the prediction of noise & vibration.
