We Engineer Quiet

Applied Acoustics International (AAI) is a Tier 1 supplier of noise, vibration, and harshness (NVH) solutions to the North American automotive industry.  Based in Chicago Heights, Illinois,  Applied Acoustics International (AAI) occupies a leading market position within the NVH industry, specializing in damper and EVA barrier materials.

Made in America

We've produced damper and barrier products for new automobiles since 1986.  We're a trusted supplier to auto makers with a long track record of successfully addressing competitive cost targets, continuous quality improvements, and just-in-time delivery requirements.  AAI’s products are critically important to a car buyer’s quality perceptions because they are engineered to help keep the interiors of vehicles quiet.  This has become increasingly important as the auto-makers integrate more technology – like hands-free communications – into almost every new platform they produce.  Applied to the inside of vehicle floors, trunks, roofs, doors, and side panels – AAI products dampen and reflect metal vibration and road noise to keep cars quiet.
