Summary:

Noise level results for a range of types of truck tire tread patterns and road surfaces are discussed. Some of the results of noise level in dry conditions are related to braking grip in wet conditions, showing that it is possible to increase wet grip and still reduce noise level.Computer studies using the mechanical frequency modulation method of predicting dominant tread pattern frequencies from tread segment pitch variations are dealt with including an automatic optimization procedure.A further development which includes the detail of the tread pattern in the segment as input to the computer gives closer prediction of higher harmonics of more complex tread patterns.Recent tests on total traffic noise after resurfacing the Hammersmith fly-over in London, England, have shown almost a 3dB(A) reduction with Delugrip Road Surfacing Material compared with the original British Standard Hot Rolled Asphalt
