-Presentation by JASIC – Japan Suggestions for AVAS Sound Requirements – Part 2 Measurement in Real-World Conditions

In follow-up to study data reported in the 3rd QRTV GGTR IWG meeting, JASIC presented “real-world” test results that support adoption of sound requirements that contain at least 2 distinct 1/3 active bands. This data verifies that there is a proportional relationship between audible distance and overall sound pressure. Therefore, this report concludes the volume of the approaching sound should be determined by the required audible distance.
