NOISE SPECTRA OF TWO VEHICLES DRIVING UPON AN INTERRUPTED METALLED EDGE STRIP FIXED TO AN ASPHALT ROAD

GELUIDEMISSIESPECTRA VAN TWEE VOERTUIGEN RIJDEND OVER EEN ONDERBROKEN STEENSLAGSTROOK

Noise measurements were performed at short distances from a passenger car and a truck to determine the effect on sound emission of driving upon an interrupted metalled edge strip fixed to an asphalt road. The passenger car was driven at a speed of 80 and 100 km/h, the truck at a speed of 60 and 80 km/h. The results are expressed in the equivalent sound pressure level in 30 successive 1/3-octave bands with central frequencies between 25 and 20000 Hz. After spectral analysis, all results were converted to A-weighted sound pressure levels. For the truck, driving on the metalled edge strip resulted in a 2-3 dB increase in the sound pressure level in frequency bands from 80 Hz to 200Hz; for the passenger car a 2-5 dB increase in frequency bands from about 80 Hz to 1000 Hz was obtained.
