Room Acoustics – Measurement, Calculation and Design

Good room acoustics are decisive for speech intelligibility, concentration and the pleasant use of a space. Depending on how a room is used – for speech, teaching, meetings or music, for example – its acoustic properties have to meet different requirements.

Excessive reverberation times can lead to high noise exposure and impaired speech intelligibility, particularly in classrooms, day-care centres, meeting rooms, offices and event spaces.

We support you both in the design of new rooms and in the acoustic optimisation and measurement-based assessment of existing ones.

From design to measurement-based verification

Three-dimensional room simulation allows even complex rooms to be investigated acoustically while they are still being designed. Different materials, absorber surfaces and their arrangement can be compared with one another and optimised in terms of their acoustic effect.

In existing buildings we record the actual room acoustic conditions by means of on-site measurements. On this basis, existing deficits can be assessed and suitable improvement measures developed.

Once construction is complete, the room acoustic properties achieved can be verified and documented by measurement. We also carry out such measurements as evidence within DGNB certification.

Typical fields of application

We support projects in schools and classrooms, day-care centres, office and conference rooms, meeting rooms, event and multi-purpose spaces, assembly halls and hospitality venues, as well as existing rooms with excessive reverberation times or impaired speech intelligibility.

From room acoustic design through measurement and simulation to optimisation and final measurement-based documentation, we accompany your project across all relevant design and construction phases.
