An apparatus is provided to directly measure the flow noise characteristics of both acoustic sensors and accelerometers mounted in a towed array hose. Sensors can be mounted in a full-scale diameter array module test apparatus and can be subjected to high Reynolds number flow fields that have the physical features of at-sea towing conditions. Additionally, rapid re-design of sensor mountings, hose materials, and actual sensors can be accomplished and evaluated. The parameters of internal tension and flow speed can vary independently in order to determine their importance.
