EXPOSURE AND RESPONSE TO TRAFFIC NOISE
The paper reviews research on the measurement of traffic noise and the development of the equivalent sound level leq as a unified measure of noise. The development of a measure of level revealed that subject bias could affect absolute judgements in the experimental situation. The factors causing bias are avoided if a random sample of the population are asked to make a judgement of their home environment at their homes. The work on the development of noise scales required a carefully structured sample of the population to ensure a balanced distribution of data across the range studied, 60 to 80 db(a) on the scale of L10(18 hour), and it could be argued that this structuring may introduce a bias into the absolute response data reducing its value for the establishment of norms. A national survey has been undertaken of the impact of roads and traffic on a representative cross-section of the English population interviewed in their homes and this was supported by noise and traffic measurements. /TRRL/
