The Design and Validation of Simulated Indoor Passby Noise Measurement System

The indoor simulated pass-by noise measurement system is the measurement tool to evaluate the pass-by noise at the test laboratory, without doing measurement at the field. This measurement system can overcome the limitations of the field measurement, i.e. weather conditions, repeatability.

The array techniques can be applied to this measurement. The reliability of the obtained result depends on the array shapes, which can investigate the moving source effect. In this paper, the way to obtain the optimum microphone array shape is proposed, and evaluated with the measurement.
