Abstract The study of indoor pass-by noise test based on acoustic array technology was carried out. The synthetic algorithm of acoustic array signal was established. In view of the problem that the vehicles running state is different from the outdoors when the pass-by noise is tested indoors. A method for getting correct loading parameters of the chassis dynamometer by modifying the coast-by speed range was proposed to ensure the indoor vehicle running state agrees with the outdoors. Finally the absolute error between the indoor and outdoor pass-by noise test results was within±1dB.
