The noise reduction in the ventilation system of buildings is the main challenge in every ventilation project. Silencers were created as the solution for this task. Therefore, Halton, a company that is the leader in indoor quality solutions, was interested in starting production of their attenuators in addition to other ventilation equipment.
The main aim of the thesis work is to find the silencer manufacturer that produces the best-performing product compared to other suppliers. Another aim is to get acquainted with the silencer’s performance during laboratory tests. In the future, Halton intends to develop its attenuators based on the structure and performance of the selected silencers.
The work started by researching the literature sources using Kaakkuri e-library and answering the following questions: What is an attenuator? What are the main parameters that can help to determine an excellent silencer from an average one? What tests have to be conducted to obtain these parameters? After the theoretical part was finished and the needed information was collected, the practical part was begun. Two tests were performed, and a comparison between the collected data and the manufacturer’s data was made.
The study showed that not all the companies wanted to connect for future cooperation. However, Alnor was selected as a potential silencer supplier despite some controversial points. The test results obtained in the laboratory sometimes were far from the values provided by the manufacturer.
