Calculation of the Insertion Loss of Barriers on Rigid Ground in the Time Domain
Source abstract
Abstract
This paper presents a method for calculating the insertion loss of barriers on the ground. The method combines the classic imaging method for an analysis of sound propagation with the secondary source model for diffraction by barriers in the time domain, which is different from other frequency-domain methods. The validity of the proposed method is verified by comparing the theoretical results with those derived from the MacDonald method, and a valid approximation for the infinite barrier is discussed.
