In December 2020, the expert committee on building and room acoustics of the German Acoustics Society (Deutsche Gesellschaft für Akustik e.V.) published a memorandum on the assessment of noise from technical building systems.

It has been published under the name DEGA BR 0105 and can be downloaded from the DEGA website.

In this memorandum, a new calculation method for the assessment of technical building equipment installations is proposed, which is based on the principle of the assessment level in accordance with TA Lärm.
