Motor Racing Vehicles - Measurement Methods

Summary and conclusions

Based on the existing pool of noise data, two simple methods for measuring noise emission from motor racing vehicles have been formulated.

The declaration method is intended for provision of noise emissions values for a type or class of motor sports vehicles to be used as input to noise predictions around racetracks. The method is based on measurement of L_eq during passby of a number of vehicles at full load of the engine. The uncertainty is estimated to be 3 dB.

The monitoring method is intended for surveying the noise emission of individual vehicles during racing events. The method is based on measurement of L_pAmaxF during passby at full load of the engine. The uncertainty is estimated at 4 dB.
