The demand for more natural and realistic auralization has resulted in a number of approaches to the time domain implementation of directional sound sources in wave-based acoustic modelling schemes such as the Finite Difference Time Domain (FDTD) method and the Digital Waveguide Mesh (DWM). This paper discusses an approach for implementing simple regular directive sound sources using multiple monopole excitations with distributed spatial positioning. These arrangements are tested along with a discussion of the characteristic limitations for each setup scenario.
