Technical Excellence in Noise & Vibration Analysis

Noise and vibration analysis is becoming increasingly important in virtually every industry. The need to reduce noise and vibration can arise because of government legislation, new lightweight constructions, use of lower-cost materials, detectability, fatigue failure or increased competitive pressure. Wave6 is ideal to evaluate noise and vibration performance during the design stage for a wide range of industries. It helps in reducing the risk of discovering expensive problems late in the design cycle when physical prototypes become available.

Applications of Noise and Vibration Analysis

Explore the multifaceted applications of Wave6 in noise and vibration analysis across various industries. The prominent industries that reap Wave6’s benefits include Aerospace & Defense, Consumer Goods, Marine & Offshore, and Transportation & Mobility. This overview offers the intricacies of Wave6 capabilities for each sector, from reducing interior aircraft noise to optimizing loudspeaker designs, and discovers how Wave6 contributes to precision analysis, safeguarding innovation and compliance with industry standards.
