Abstract

Directional sound radiation by a cylinder surrounded with an arc-shaped (open circular) acoustic screen is examined. The corresponding boundary problem is solved with the partial domain technique. The method of asymptotic solutions was used to verify the conditions of solving this problem using the method of simple reduction. As a result of the analysis, the quantitative characteristics of the acoustic field of the cylindrical radiator inside the arc-shaped screen were evaluated.
