We developed a compressed air silencer. It is useful on adsorption air dryers, which cause a large amount o fair to be released during operation, creating noise. In the thesis, we created several conceptual solutions, which we tested with computational fluid dynamics, some of the solutions were also tested experimentally and compared to the existing solution. The best experimental solution suggests a noise reduction of about 6 dB, which corresponds to about 4x lower sound levels of noise.
