Portable Sound camera model SeeSV-S205 is a real-time handheld sound camera which implements FPGA-based high speed beamforming technology. It is developed for Buzz, Squeak and Rattle (BSR) noise source detection as well as Noise, Vibration and Harshness (NVH) source visualization. It displays transient noise effectively due to its high image per second update rate. The unique design of SeeSV-S205 makes measuring sound easy.

The SeeSV-S205 has 30 microelectromechanical system digital microphones arranged in five spiral arrays. Using a beamforming algorithm running on the FPGA, the acoustic camera can detect and locate both stationary and moving noise sources. A high-resolution optical camera in the middle of the device records images at a rate of 25 fps. The resulting high-speed colormap overlay and video are ideal for identifying transient sources of noise.
