ESI VA One not only guided us towards efficient, optimal vibro- acoustic solutions, but also led the way in assessing active noise control methodology.
Greg Kangas, Engineering Project Leader Great Lakes Sound & Vibration


After teaming up with the US Army (TARDEC), GLSV was looking for a way to develop an efficient Active Noise Cancellation (ANC) system to reduce intake and exhaust noise and high-performance fan noise for fans and blowers in military ground vehicles and power generation applications.


Founded in 1996, Great Lakes Sound & Vibration (GLSV) opened their doors to solve acoustic, shock, and vibration problems. Today they are a multi-functional engineering company that features a strong background in defense, marine, automotive, off-highway and recreational vehicle markets. Their strength lies in their diversity and ability to solve challenging problems that require a broad range of knowledge and varied capability. When GLSV teamed up with the United States Army Tank Automotive Research, Development and Engineering Center (TARDEC), the goal was to develop Active Noise Cancellation (ANC) system for reducing intake and exhaust noise and high-performance fan noise for fans and blowers used in military ground vehicle and power generation applications.


Using ESI VA One, GLSV was able to design, analyze, and validate the development of active noise control (ANC) systems for cancellation of exhaust and fan noise in all phases of the development cycle. The main benefit? Reducing the time in the product development cycle.
