Track 7: Noise Evaluation

Track 7 Map

Overview

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.
