Abstract: The screening effect of balconies on a building facade in the case where the noise source is not parallel to the facade is studied using scale model experiment in the present study. Results show that the angle of source inclination to the facade has substantial effects on the balcony insertion loss in the presence of a traffic noise spectrum. Less amount of noise amplification is observed when the source is inclined compared to the case of parallel source in the presence of balcony ceiling reflections. Regression formulae in terms of three independent angles which determine the positions of the balcony and its ceiling relative to the noise source are developed for the prediction of balcony insertion loss. The discrepancy between measurements and predictions is within engineering tolerance.
