Possibility of “Pass-by-Light” Noise-measurement of vehicles of Category L (Germany)

The study found that such equipment provides a "lite" version of the UN 41.04 procedures that is useful in evaluating real-world performance. Germany intends to pursue a national "pass-by lite" test directive for UN R41-approved motorbikes and for non-original replacement exhaust silencer systems (NORESS) roadside and periodic technical inspections.
