A method to reduce wall mounted boiler noise pollution by a sustainable approach

The mechanisms involved in the operation of the wall-mounted boilers are the primary source of noise pollution, which bothers users while operating. One of the most basic solutions is to control the amount of noise by using insulator materials. The material must have acoustic absorption characteristics and high heat resistance. In this study, four acoustic materials based on polymer resins, glass wool and stone, and jute fabrics that have good degradability in nature have been studied as noise control materials. Based on the physical and chemical properties of the acoustic insulating polymers, high noise absorption is generated and flammability is preserved at high temperatures too. The nature of acoustic absorption and high degradability is also noticeable in jute fabrics. For the shell sound control tests, several wall-mounted boilers have been used in this study, and the sound waves have been measured using a B K 2260 measuring device. The overall rate of noise reduction in monolayer and blended double-layer insulators has been compared. Although the monolayer or double-layer insulators perform better than jute ones, the acoustic absorption standard of the wall-mounted boilers can also be achieved by using jute. Therefore, due to environmental conditions, the jute is approved as a sound insulator.
