Interfering and undesired sounds are sometimes propagated from room to room. This is often the case when buildings are subject to diverse uses. For example, this happens when comparably silent residential space meets noisy domestic service facilities or public areas such as a gym or movie theatre.

To ensure harmonious interaction after all, we can recommend building-acoustic measures during the planning stage already to minimise the transfer of air-borne and footfall sound within buildings. Correctly sized exterior structures help optimise buildings so that traffic noise stays where it belongs: outside.

• Proof of noise reduction in accordance with DIN 4109 “Noise reduction in structural engineering”
• Metrological investigation of existing buildings
• Structural acoustic investigations of domestic service facilities, lifts, ventilation systems, compressors and installations
• Development of acoustic improvement measures to increase protection against noise
• Structural acoustic design and execution plans for new constructions
• Building monitoring and inspection of the building execution
• Measurement of the air-borne and footfall sound insulation of parts on the structural acoustics test facilities
• Quality testing in accordance with DIN 4109 for quality assurance or if in cases of complaints after commissioning

Room acoustics: A perfect home for sound.

To prevent sound from spreading uncontrolledly, and to make sure that it never feels less than comfortable, our engineers create optimised acoustic properties for rooms of any kind. These rooms may even be theatre or concert halls. This is where sonority is at the centre of considerations. These tasks are typical for us in educational facilities such as schools, day-care centres or gyms as well, however.

Does that sound good to you? It may sound even better that we also offer solutions for projects that focus on intelligibility of speech or reduction of noise levels. One thing never changes with us: We will explain every solution comprehensibly enough to make it resound with you for a long time and help you keep it in good memory.

• Room-acoustic design and execution plans for new constructions
• Computer simulation of sound propagation
• Echoing time measurement and calculation
• Optimisation of primary and secondary structures of rooms
• Measurements to determine room-acoustic parameters such as clarity, distinctiveness, emphasis, etc.
• Development of measures to improve existing buildings
• Building certification services (DGNB, LEED, etc.)
• Variable measures for multi-purpose uses (e.g. in churches or town halls)
