title: Sleep Studies Before and After - Results and Comparison of Different Methods.
abstract: The effects of long-term exposure to road traffic noise on sleep quality were assessed using questionnaires and actimetry. Results obtained before and after reduction in road traffic were compared. Sleep quality was improved after the reduction of noise levels. There was some correlation between actimetry parameters and subjective parameters.
