While traffic noise is unlikely to cause hearing damage to those exposed outside the vehicle, it does cause a number of other harmful effects. It interrupts communication between people by interfering with conversation, the use of the telephone, or listening to radio or television. It often disturbs sleep. Noise adds appreciably to the stress of the human body and it is now thought that it can contribute to heart and circulatory disease and add to existing disease. There is now evidence that excessive noise may threaten foetal development and mental health. Noise has special adverse effects on children. It can directly interrupt learning and thus adversely affect reading ability and the ability to listen. It affects human performance at work in terms of productivity and work force turnover, and noise has contributed directly to accidents by masking warning signals. This article presents a short review of noise control strategies in New Zealand, Switzerland, USA and England. Two tables show permissible noise levels in New Zealand, Australia, USA and Japan. Table 1 shows the levels achieved based on the ISO R362 drive-by test, and table 2 shows the planned levels to be achieved by the use of existing and proven vehicle technology. (TRRL)
