There is no evidence of direct physiological effects of of noise of the levels encountered in traffic, but it may however 1) make verbal communication difficult 2) interfere with complex task performance 3) interfere with sleep. Estimates are presented of the proportion of urban residential roads exposed to noise levels sufficient to produce these effects now and in the future. Methods of traffic noise reduction are then discussed: reducing intensity at source; deflecting or shielding noise between the road and the people affected; the insulation of buildings. The concluding section briefly attempts to place a monetary value on noise. The number of the covering abstract of the textbook is IRRD abstract no 212297. /TRRL/
