Room acoustics

Acoustic room design – ranging from hotel rooms to concert halls#

Room acoustics surround and influence us whenever we are in buildings or rooms. Depending on the type and extent of use, different acoustic conditions are required in order to optimize the use of space. Room acoustics have a significant impact, for example, on our work or learning performance in open-plan offices or classrooms, on intelligibility in conference rooms or studios, and on our sense of well-being in hotel rooms or at home.

In concert halls and opera houses, excellent room acoustics are essential to the quality and reputation of the entire building. In the case of loud industrial workplaces, acoustic room design helps to meet legal requirements and improve working conditions. A room acoustics system that is both economical and use-oriented requires precise planning as well as the utilization of acoustically-effective materials and constructions.

For many of these room types, our experts develop concepts and components (sound absorbers) that ensure acoustic efficiency while also supporting architectural planning processes and contributing to other room functions. To achieve this, we implement the standards and guidelines applicable to room acoustics, such as DIN 18041, ISO 3382, VDI 2569, and others. Furthermore, we question and further develop these and are actively involved in shaping them. We use modern tools such as simulation and measurement technologies, as well as auralization for planning and developing sound absorbers. The acoustic quality of rooms and components is evaluated with a wide range of measuring methods applied on-site or in special measurement rooms.

Sound absorbers

Have you ever thought about why the acoustics in halls and atriums do not always sound as if you are in a cathedral? This is because so-called sound absorbers are used, which can significantly influence and alter room acoustics. We develop these components for various situations and applications, always taking the architecture into consideration.

Simulation and auralization of room acoustics

Although room acoustics are usually only perceived subconsciously, they must be planned carefully in order to be effective. By simulating acoustics in rooms, our experts can verify and optimize plans on the computer. Furthermore, auralization enables acoustics in rooms to be heard in advance.

Acoustics in open-plan offices

When planning and constructing modern office space, open-plan offices are becoming increasingly popular. The acoustics in such rooms has a decisive effect on the well-being and work performance of employees. Our experts are conducting research in order to develop better concepts and solutions.

Acoustics in schools and sports halls

Successful teaching in schools and sports halls requires a quiet environment and good speech intelligibility. Constructive measures can optimize both aspects. We are working on adapting more than just the acoustic properties of installations and components for these rooms.

Acoustics in hotels and restaurants

Have you ever left a restaurant and realized how incredibly noisy it was? The acoustics in dining rooms and hotels play a major and often only subconsciously perceived role on the length of stay and comfort of the guests. We investigate what constitutes excellent room acoustics and how to design it.

Measurement-based validation

Acoustic room design comprises many aspects and needs to be planned and implemented individually according to usage. We perform measurement-based tests to determine and validate acoustic conditions. The results are then compared with specifications or subjective assessments. Our experts provide the necessary know-how.
