In HVAC systems, ducts distribute more than air; they also distribute noise produced by fans. Duct liners (Photo A) were developed in part to absorb noise before it emanates from ductwork. Designers apply different thicknesses and lengths of duct liner to reduce noise to various levels. Understanding the acoustical benefits of duct liners and the available choices in liner materials helps in specifying a system that is efficient and effective, both in terms of noise
