Sound Power

Sound Power is a key metric for regulartory compliance, benchmarking and competitor analysis, as well as being useful for promotion. Depending on the size and the emitted acoustic level of the device under test, the GRAS hemispheres allow for sound power measurements on everything from small size personal electronics, office machines and IT products, household appliances to power tools and smaller engines. Have you ever tried positioning 10 tripods in a hemisphere? If so, you'll appreciate the ease, accuracy and repetability of the GRAS Hemisphere.
