Acoustic treatment of interiors with non-standard geometry – case study

When designing acoustic treatment for interiors with non-standard geometry, we often have the opportunity to consider unfavourable phenomena that disturb the proper perception of sound. The determinants are usually the expected functions of the room, the expected acoustic parameters and the type of sound system [1]. The paper presents selected results of model and experimental acoustic tests of two interconnected rooms created by horizontal division of the hall, one of which retains its arched vault. Taking into account the need to adapt a larger interior to accommodate small musical forms, performances and meetings, an attempt was made to correct acoustic defects and even use the unfavourable concavity of the ceiling to support the first reflection of sound. The summary also indicates material proposals enabling the implementation of the proposed solutions.
