UNUSUAL METHODS OF MEASURING SOUND ABSORPTION COEFFICIENT: SMALL-SIZED REVERBERATION CHAMBERS
Original language description
This study is focused on solving a problem with the lack of measuring methods suitable for sound absorbing materials development. The conventionally used sound absorption measuring methods require either samples too large to be time-effective and economical in the early development stage, or too small to describe the material acoustic behaviour in sufficient detail. Thus, this study aims to find a suitable substitutional method that could replace the usually used ones. It focuses mainly on the topic of small-sized reverberation chambers. The practical part focuses on measuring in the Alpha cabin, an industrially used small-sized reverberation chamber. The measurement is performed in a modified version suitable for concrete samples with an unconventional size of 400x400 mm. The results are compared with the ones measured by the impedance tube method; based on the results, it is decided that this method is suitable for larger samples.
