This SAE Recommended Practice establishes the test procedure, environment and instrumentation for determining maximum sound level potential for motorcycles.
This SAE Standard establishes the test procedure, environment, and instrumentation for determining the sound levels of motorcycles under stationary conditions. This test will measure primarily exhaust noise and does not represent the optimum procedure for evaluating total vehicle noise. For this purpose, SAE J331 or SAE J47 is recommended.

This document establishes the test procedure, environment, and instrumentation for determining the sound levels of motorcycles under stationary conditions. This test will measure primarily exhaust noise, but does not represent the best procedure for evaluating total vehicle noise. For this purpose, SAE Recommended Practice J331a, Sound Levels for Motorcycles, or SAE Recommended Practice J47, Maximum Sound Level Potential for Motorcycles, are recommended.
This engineering design specification provides parameters and general requirements for auxiliary front lamps to be used on motorcycles. It may be supplemented by a service performance requirement.
