In 1974 a study was carried out in ten French towns comprising noise measurement and a psycho-sociological survey of 1000 respondents in order to estimate the annoyance caused to people living close to expressways. The main object of the research was to establish, for legislative and regulatory purposes, a suitable noise index, together with a noise level acceptable to residents adjacent to major traffic routes, to relate the annoyance to the major activities disturbed by noise, and to the socio-demographic characteristics of the population studied. Annoyance was shown to be related to measured noise levels. For the period 08.00-20.00 hours the equivalent noise level (leq) is proposed as a suitable unit and it is suggested that noise levels should not exceed 65 db(a). Heavy lorries were found to constitute major sources of annoyance, l1 for the period 20.00-24.00 hours is proposed as a l1 for the period 20.00-24.00 hours is proposed as A suitable measure, with levels not permitted to exceed 70 db(a). For residents in bungalows, levels need to be somewhat lower. In two of the towns studied, a second survey was carried out after an interval of two years. It was found that the level of annoyance had not declined during this period and it is concluded that no habituation to noise had taken place. /Author/TRRL/
