Volume Velocity Source Measurements

Volume velocity sources (VVS) measure acoustic transfer functions (ATF), typically in connection with noise source contribution analysis. Uniquely, HBK volume velocity sources use a special dual-microphone probe to measure accurate volume velocity directly in real time. 

BK Connect VVS Measurements is designed to work with HBK VVS devices to help you make high-precision ATF measurements quickly and efficiently based on a pre-loaded test plan that guides you through the measurements to ensure the best quality results.
