SPEED INFLUENCE ON TIRE/ROAD NOISE INSIDE A PASSENGER CAR
The paper contains detailed analysis of the speed influence on the level and frequency spectra of the tire/road noise inside a passenger car. A special experiment performed to estimate the influence is described and its results discussed. Different noise-speed characteristics were obtained for interior and exterior tire/road noise. As was expected, the sound levels of exterior noise are proportional to the logarithm of the speed. Tire/road noise inside a cabin of passenger car is not governed by the same rules. The speed influence on A-weighted sound pressure level is linear. The noise level increases on the average 1.2 dB(A) per 10 km/h. In the frequency domain speed-dependent and speed-independent tire/road noise generation mechanisms were observed and discussed in the paper. For the covering abstract see ITRD E107776.
