Using finite element modeling in the COMSOL Multiphysics software package, the influence of attachments on the upper edge of a flat acoustic barrier on its efficiency was investigated. Attachments of various configurations were considered. Generalized insertion losses were used as the efficiency indicator. Dependencies of the attachments’ efficiency on their configuration and the position of the sound source relative to the barrier were obtained.
