A decentralized ventilation system is a type of ventilation system that consists of multiple smaller units distributed throughout a building, as opposed to a centralized system with a single large unit. Each unit in a decentralized system is responsible for ventilating a specific area or zone, allowing for more precise control and energy efficiency. These systems often use heat recovery technology to recapture and reuse energy from the outgoing air, further increasing their efficiency. Decentralized ventilation systems are becoming increasingly popular in modern building design due to their ability to provide better indoor air quality and energy savings. **

To soundproof a decentralized ventilation system, you can start by adding acoustic insulation around the ductwork and in the walls around the system. This will help to absorb and reduce the transmission of sound. Additionally, you can install vibration isolators on the fan and motor to minimize the transfer of noise through the structure of the building. Finally, consider using sound baffles or acoustic panels in the room to further dampen any remaining noise. **
