Sound Absorption Coefficient Measurement at TÜBİTAK BUTAL

Share This News

At TUBITAK BUTAL, sound absorption coefficient and sound transmission losses can be measured with large and small impedance tubes.

According to ISO 10534-2 and ASTM E1050-12 standards, acoustic properties of samples with diameters of 29 mm and 100 mm can be measured with tests that can be applied to various materials in the range of 50-6400 Hz. In impedance tube tests, it is necessary to pay attention to the precision of cutting the material samples in the desired dimensions, and the measurement results are analyzed with the appropriate computer program and the requested information is reported.
