General description

The Architectural Technology Laboratory of the AUTH has special equipment for the measurement of the sound insulation in the worksite and the determination of the sound reduction indicator R and of the level of impact sound L of structural elements, in accordance with the requirements of standards:

DIN EN ISO 140-4:1998-12    Akustik - Messung der Schalldämmung in Gebäuden und von Bauteilen - Teil 4: Messung der Luftschalldämmung zwischen Räumen in Gebäuden

DIN EN ISO 140-5:1998-12    Akustik - Messung der Schalldämmung in Gebäuden und von Bauteilen - Teil 5: Messung der Luftschalldämmung von Fassadenelementen und Fassaden an Gebäuden

DIN EN ISO 140-7:1998-12    Akustik - Messung der Schalldämmung in Gebäuden und von Bauteilen - Teil 7: Messung der Trittschalldämmung von Decken in Gebäuden

ISO 717-1:1996    Acoustics - Rating of sound insulation in buildings and of building elements - Part 1: Airborne sound insulation, International Organization for Standardization.

ISO 717-2:1996    Acoustics - Rating of sound insulation in buildings and of building elements - Part 2: Impact sound insulation, International Organization for Standardization.

For the realization of these tests it is essential to check the conditions that prevail in the worksite. During the test, the work might be required to stop or there might be the need for some special temporary constructions in order to meet the requirements of standards. The on-site tests of structural elements are not included in the accreditation field of the Laboratory.

The procedure of the test includes the installation of the sound sources and the measuring microphones and the realization of the test that is checked by a computer and lasts up to 4h.

The on-site tests of structural elements which are realised by the Laboratory concern particularly:
