Image Source Method

The Image Source Method (ISM) is a computational technique for simulating room acoustics, primarily used to generate room impulse responses (RIRs) representing how sound propagates in enclosed spaces. Current research focuses on improving ISM accuracy by incorporating factors like transducer directivity and developing advanced algorithms for both generating RIRs more efficiently (e.g., through random approximations) and inversely recovering room parameters from measured RIRs. These advancements are significant for applications such as speech processing, acoustic scene analysis, and sound absorption estimation, enabling more realistic simulations and improved analysis of real-world acoustic environments.
