Portable sound camera and sound pressure meter for visual sound level measurement. In loud environments, it is often difficult to pinpoint the source of a sound. The easy-to-operate PCE-MSV 10 sound level meter visualizes sound in real time, creating a visual road map to a sound’s source. Also referred to as a noise meter, sound pressure meter, portable sound camera or sound level camera, the PCE-MSV 10 sound level meter can be used in various stages of machine and equipment design, manufacture and operation, from engineering research and development (R&D) to preventative maintenance and beyond.
