Tiivistelmä
The main goals of this study were to describe different methods for measuring airborne sound insulation of facades, to practice some of these methods and make field measurements and to analyze the results of measurements according to standard requirements.
The first part of this thesis is about methods which are described in the European standard EN ISO 140-5: “Field measurements of airborne sound insulation of facade elements and facades”. This standard shows various methods for measuring sound insulation of a whole facade (global methods) and facade elements, such as a window (element methods).
The second part is about measuring equipment which was used during field measurements: a loudspeaker, real-time sound analyzers and a calibrator. Features and possibilities of this equipment are described.
The third part describes field measurements. These measurements are practical applying of the Global loudspeaker method. Measurements have been done in two different places. The first place is the concrete laboratory of Saimaa University of Applied Sciences and the second place is testing building.
On the basis of these measurement results test reports were made. In these reports the results are presented graphically and as standardized level difference D1s,2m,n,w. This value for the concrete laboratory facade is 22 dB and for the testing building facade in the second case is 29 dB.
