Road Traffic Noise Interventions: Development of a Method to Quantify their Effects on Annoyance and Sleep Disturbance on a Small Urban Scale

Road traffic is the main source contributing to noise exposure in urbanized areas. With the rapid urbanization and the increasing attention on the way sound can affect health and well-being, the question is how to shield ourselves from harmful effects. The most common noise intervention research studies regard only large-scale interventions, like noise barriers along a highway, the effect on health and well-being are often based on rough estimations of sound reduction. In this study, the effect of a small scale intervention on annoyance and sleep disturbance will be investigated, considering relative changes in dose-response relationships to account to local effects. It will give more insight into the subtle changes due to interventions on a local scale, providing more detail on top of existing conventional studies. To develop this methodology an intervention study in Rotterdam is taken as a test case. The location and its intervention are modeled using 3D-geometrical acoustic software (Olive Tree Lab). The predicted noise reduction due to the interventions, as well as the predicted health effects are compared with measured data and local surveys. The results shed a light on the suitability of this approach to predict health effects due to interventions at a local scale.
