ISO 10140 - 2 Airborne Sound Insulation of Building Elements
This facility consists of two adjacent rooms with an opening in between for the sample to be installed. This adjustable opening allows window elements of 1250 x 1500 mm, door elements of 1250 x 2200 and other larger test samples of 3910 x 2590 to be quickly installed and tested. After the sample is checked thoroughly for leakage,the noise level of the rooms with the source and receiver are measured and the difference is found. All measurements are done at the third octave and 50-5000 Hz frequencies according to ISO 10140-2, and as a result, a final value describing the general acoustical performance is found.
