Sound camera helps to identify car problems

A portable sound camera has been developed that could help pinpoint the exact location of problems inside of machines and cars.

While other similar devices are already in existence, they're generally larger, heavier contraptions that need to be assembled and mounted on a tripod. The SeeSV-S205 is light enough to hold in one hand and weighs in at just 1.78kg. The pentagonal-shaped camera has five spiral arrays of 30 highly sensitive digital microphones. These work to detect transient and stationary noise sources by utilising fpga based high speed beamforming technology. With a high resolution optical camera installed in its centre, SeeSV-S205 is capable of capturing 25 sound plus visual images per second. Professor Seok-Hyung Bae, from the department of industrial design at South Korean institute KAIST, said: "Abnormal noises coming from industrial products have relatively higher frequencies. "Our model has adopted a measurement range of high frequencies between 350 and 12 kHz, thereby reducing its size and weight by 60 and 70 %, respectively, without compromising performance compared to conventional models of sound cameras. "SeeSV-S205 offers portability, which I believe will spur the wider application of our sound camera to many industries, automotive manufacturing in particular."
