Track 7: Noise Evaluation

Track 7 Map


Track 7 is used for noise evaluation. It includes a drumming surface that accentuates low frequency noise, useful for evaluating interior noise. Another area of this track offers special surfaces and highly-sensitive microphones for measuring pass-by noise. Track 7 also includes an underground camera station that Michelin uses for evaluating how tire treads disperse water.
