Motor Racing Vehicles - Measurement Methods

7 Concluding remarks

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

The declaration method is intended for provision of noise emissions to be used as input to noise predictions around racetracks. The method is based on measurement of L_eq per 1/1-octave during passby at full load of the engine. The 1/1-octave uncertainty is estimated to 3 dB provided at least 30 passbys of at least three vehicles is used

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 for an average value of four measurements.
