Portable Sound Camera

SeeSV-S205

Overview

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.
