2 Ways EV Manufacturers Are Enhancing NVH Performance

Automotive lightweighting design trends such as lower gauge metal panels and higher numbers of panel holes negatively impact a vehicle’s NVH performance.  This is especially true in electric vehicles.

Echo is adept at improving NVH characteristics using custom-designed EPDM panel plugs and butyl damping patches. EPDM is a top material for improving NVH characteristics due to high sound and vibration absorption, great tensile strength, and extreme environmental stability. Butyl foil also has great NVH dampening qualities and can be easily applied to complex part geometries.   

Vehicle ride characteristics and perceived build quality are key competitive advantages.  Models that produce the most pleasurable NVH experience will be preferred by end-users.  Reach out to us today so we can design a custom NVH solution for you.
