Development of a New Highway Traffic Noise Prediction Model. Volume 3. Indoor Validation Test Results
The volume discusses an experimental investigation of noise propagation and compares experimental results to predictions. The experiment entailed a simulation of highway noise radiation from sources on a roadway, to microphones mounted above selected ground covers. In some instances the roadway was screened by a vertical noise barrier. The experimental setup was assembled in a large gymnasium so as to minimize changes in environmental parameters and to assure wind-free sound propagation. Source frequencies were scaled up five-to-one over real highway emissions, so that received levels could be converted properly to those that would prevail at distances five times the actual gymnasium distances.
