Abstract

A novel application-specific hardware (ASH) unit was designed to form the building block of the Meshotron - a parallelisation network for three-dimensional (3D) digital wave guide-mesh (DWM) room acoustic models. The rectangular mesh topology was elected. This ASH unit was tested using professional hardware simulation tools, assuming 32-bit integer data. Room impulse responses (RIR) were obtained for a set of small models under different test conditions, using both single-unit and multi-unit configurations. They proved exactly identical to those obtained using 3D DWM modelling software for the same models and test conditions, which validates the design.
