Innovative silencer for window air inlets

This presentation introduces an innovative window air inlets silencer. The product is intended for exterior installation, tailored to match the standard dimensions of window air inlets, specifically the slot through the window. It is designed to complement internal window air inlet equipment. The silencer's design encompasses multiple functionalities. The main one is reducing external noise transmission (such as traffic, airport, and city center noise) from outside to inside the room equipped with the air inlet. Additionally, it minimally impacts air flow, ensures resistance to water and sunlight, offers washability for accumulated dust, and emphasizes aesthetics compared to other existing silencers. The development of the silencer involves a comprehensive approach, incorporating numerical simulations, optimizations, prototypes, and standard experimental tests. The performance of the developed silencer is compared with similar products already available in the market.
