Architectural acoustics is the sector of acoustics related to the sound field within spaces, i.e. how a source sounds in a space.

It focuses on the design of spaces of high acoustic quality depending on their use. It uses indicators whose values describe and quantify various criteria that must be met where appropriate, such as clarity and intelligibility of speech and clarity of music. In addition, noise levels within the premises must be low. This is achieved by designing and calculations to reduce noise from external sources, mechanical equipment, HVAC, etc.

Within the framework of acoustic improvement, we measure acoustic indicators, with the most important being the reverberation time, which determine the initial state of the room. Then, target limits are set, determined by the client's needs. These values can be found in standards (e.g. ISO, LEED, DIN) and scientific literature. The calculations for acoustic modification are performed using simulation software. The scientific literature includes studies that highlight the advantages of a high acoustic quality space. These include increased concentration and performance of students and employees and increased customer satisfaction in low reverberation and low noise dining areas. Places where the principles of architectural acoustics can be applied are: theatres, cinemas, classrooms, cafeterias, lecture halls, conference rooms, multipurpose rooms, office spaces, recording rooms, etc.
