The paper presents software developed for modelling and analysing the acoustic environment. The aim is to develop software for modelling and analysing complex acoustic processes in confined environments and to accelerate its operation due to modular architecture, parallelisation of computations and multi-threaded data processing in the numerical implementation of boundary value problems for acoustic equations. Methodology. A modular approach to the development of software architecture is used. Computer modelling of sound wave propagation is based on the fundamentals of mathematical physics and finite and boundary element methods for solving acoustic equations. Mechanisms to support parallel computing are used to speed up the work. The scientific novelty lies in developing software for sound wave simulation with a modular architecture that includes boundary value problems for acoustic equations, methods for their numerical analysis, and interactive visualisation of results, with the possibility of parallelising computations when solving mathematical physics equations. Conclusions. Methods of sound wave simulation have been investigated. The software has been developed with a special focus on localising sound sources using microphone arrays and optimising algorithms for processing complex acoustic scenarios. The presented solution is focused on a wide range of applications, including sound physics research and intelligent systems design.
