Milhorn, J., Rovedatti, V., DeJong, R., and Ebbitt, G., "Road Tests of the Acoustic Loads on the Back Panels of a Pickup Truck," SAE Technical Paper 2016-01-1300, 2016, doi:10.4271/2016-01-1300.
Road tests on a pickup truck have been conducted to determine the acoustic loads on the back panel surfaces of the vehicle. Surface mounted pressure transducers arrays are used to measure both the turbulent flow pressures and the acoustic pressures. These measurements are used to determine the spatial excitation parameters used in an SEA model of the transmission loss through the back panel surfaces. Comparisons are made between tests on different road surfaces and at different speeds to identify the relative contributions of acoustic and wind noise.
