Acoustical Effect Evaluation of Balconies' Ceiling Form in Protecting Buildings Facades Against Traffic Noise.

Abstract : This study presents the evaluation of acoustic performance off tall building facades closed to roadway due to one of its balconies configurations, namely ceiling, with an inclined form in terms of traffic noise reduction. Three inclined angles are tested (5`, 10`, and 15`) with different balcony depths (2m, and 3m) by using the Pyramid Tracing model (DISIAPYR) developed by A. Farina and scale model measurements. The results in terms of A-weighted sound pressure level reduction are expressed into the balcony back wall and in free field. The protection level, defined as the difference in noise levels before and after inserting the proposed ceiling form, has been used to assess the reduction offered by that configuration. A maximum reduction due to using these forms is obtained at higher floors.
