Airborne sound insulation

Construction products and construction techniques for airborne sound insulation ensure that airborne sound insulation requirements in buildings can be met.

Regulatory framework

In this work area, DIBt grants national technical approvals (abZ) and/or general construction technique permits (aBG) and issues European Technical Assessments (ETAs).

Regarding design and execution, the Administrative Provisions – Technical Building Rules of the federal states (VV TB) must be observed. Cf. the common model MVV TB, in particular Section A5 (Protection against noise).

National procedure

A national technical approval (abZ) and/or oder general construction technique permit (aBG) is granted upon application (see Model Building Code (MBO), Sections 16a(2) and18(2) and (4)). This also applies to amendments and supplements to, or renewals of existing approvals and/or construction technique permits.

No formal requirements apply. The following information is needed: name and address of the applicant, description of the product and/or construction technique and its field of use or application, type of decision required (new decision, amendment or supplement to, or renewal of, an existing decision).

European Technical Assessment (ETA)

To start the ETA procedure, please submit the form below. We will then check if the prerequisites for issuing an ETA are met, i.e., in particular, if the product is not fully covered by an existing harmonised standard. If the prerequisites are met, we will check whether a European Assessment Document (EAD) covering the requested assessment scope already exists or still needs to be developed. If an EAD needs to be developed or amended, a complete technical file needs to be established before the procedure can begin.
