Sound Power is the most universal of all acoustic metrics. Sound Power measurements can be used to make absolute comparisons between different products, predict the sound pressure level in any given environment, and determine acoustic hotspots via sound source ranking.
Bruel & Kjaer has been measuring sound power since the first international standards came out in the 1950’s. Offering complete turnkey solutions as well as individual components, Bruel & Kjaer can help you make the most accurate sound power measurements possible and ensure full compliance with any international standard.
