Acoustic analysis of coupled rooms with opposing acoustic properties

The article presents the issue of coupled rooms, i.e. a set of interconnected rooms that may interact acoustically. Rooms of this type can be found both in qualified facilities, where their acoustic properties are important and they are appropriately designed, and in ordinary buildings, where their acoustic properties are most often ignored and very random. This study presents a comprehensive acoustic analysis of coupled rooms with opposing acoustic properties – a listening room with a short reverberation time and a reverberant room. Acoustic analyses were carried out experimentally (measurements in a real facility) and numerically (comprehensive computer simulations).
