Hyundai Uses a Portable Sound Camera for Buzz, Squeak, and Rattle Studies Based on LabVIEW and FPGA

Author: Kang-Duck Ih, Hyundai Motor Group and Youngkey K. Kim, SM Instruments Co., Ltd.

Challenge: Creating a portable system to visualize and identify annoying transient buzz, squeak, and rattle (BSR) noise sources in Hyundai automobiles.

Solution: Developing a handheld sound camera with NI LabVIEW system design software that identifies and displays noise sources in real time using microelectromechanical system (MEMS) and FPGA technologies to increase the image update rate and to decrease the total weight of the device.
