The assembly includes a single housing defining an internal chamber, at least one sound-absorption member within the internal chamber, wherein the at least one sound-absorption member is configured to dampen sounds generated by or within the air handling system, and an insulative material within the internal chamber, wherein the insulative material is configured to insulate the air handling system. ## Claims ### Claim 1 An assembly configured to provide insulation and sound-dampening within an air-handling system configured to condition air within an enclosed room of a building, the assembly comprising: a single housing defining an internal chamber; at least one sound-absorption member including at least one sound-absorption insert within the internal chamber, wherein the at least one sound-absorption member is configured to dampen sounds generated by or within the air handling system; and an insulative material within the internal chamber, wherein the insulative material is configured to insulate the air handling system, wherein the at least one sound-absorption insert is retained within at least one tray within the internal chamber, wherein the at least one tray includes a base and outer walls, wherein the base and outer walls are distinct from the insulative material, and wherein the at least one tray is connected to the single housing. ### Claim 2 (depends on 1) The assembly of claim 1, wherein the at least one sound-absorption member and the insulative material are contained within a volume defined by a frame. ### Claim 3 (depends on 2) The assembly of claim 2, wherein no portion of the at least one sound-absorption member or the insulative material extends past a width, height, and depth of the frame. ### Claim 4 (depends on 1) The assembly of claim 1, wherein the at least one sound-absorption member is formed of fiberglass. ### Claim 5 (depends on 1) The assembly of claim 1, wherein the at least one sound-absorption member comprises a plurality of aligned sound-absorption members. ### Claim 6 (depends on 1) The assembly of claim 1, wherein the at least one sound-absorption Member comprises a single sound-absorption member that has an area equal to at least one surface of the single housing. ### Claim 7 (depends on 1) The assembly of claim 1, wherein the insulative material comprises a foam that is injected into the internal chamber. ### Claim 8 (depends on 7) The assembly of claim 7, wherein the foam comprises a polyurethane foam. ### Claim 9 (depends on 1) The assembly of claim 1, wherein the single housing comprises a frame connected to first and second plates, wherein the internal chamber is defined between the frame and the first and second plates. ### Claim 10 (depends on 9) The assembly of claim 9, wherein at least one of the first and second Plates comprises at least one sound passage section proximate the at least one sound-absorption member, wherein the at least one sound passage section comprises a plurality of sound passages that allow sound waves to pass therethrough and into the sound-absorption member. ### Claim 11 (depends on 10) The assembly of claim 10, wherein the at least one sound passage section comprises at least one perforated sheet secured to at least one of the first and second plates. ### Claim 12 (depends on 10) The assembly of claim 10, wherein the at least one sound passage section is integrally formed into at least one of the first and second plates. ### Claim 13 A method of forming an assembly configured to provide insulation and sound-dampening within an air-handling system configured to condition air within an enclosed room of a building, the method comprising: forming an outer frame for the assembly; securing first and second plates to the outer frame so that an internal chamber is defined between the outer frame and the first and second plates; defining at least one sound-absorbing insert area within the internal chamber; injecting an insulative material into the internal chamber; allowing the insulative material to expand and set within the internal chamber; connecting at least one tray within the at least one sound-absorbing insert area and to at least one of the first and second plates housing, wherein the at least one tray is distinct from the insulative material; and securing at least one sound-absorbing insert into the at least one tray. ### Claim 14 (depends on 13) The method of claim 13, further comprising covering the at least one sound-absorbing insert with at least one perforated sheet that secures to one or both of the first or second plates. ### Claim 15 (depends on 13) The method of claim 13, wherein one or both of the first or second plates comprises at least one sound passage section formed therethrough, and wherein the at least one sound passage section aligns with the at least one sound-absorbing insert. ### Claim 16 An assembly configured to provide insulation and sound-dampening within an air-handling system configured to condition air within an enclosed room of a building, the assembly comprising: a single housing including a frame connected to first and second plates, wherein an internal chamber is defined between the frame and the first and second plates, wherein the internal chamber is contained within a volume defined by a width, height, and depth of the frame, wherein at least one of the first and second plates includes at least one sound passage section having a plurality of sound passages; at least one sound-absorption fiberglass insert secured within the internal chamber, wherein the at least one sound-absorption fiberglass insert is proximate the at least one sound passage section, wherein the plurality of sound passages allow sound waves to pass into the sound-absorption fiberglass insert, wherein the at least one sound-absorption fiberglass insert is configured to dampen sounds generated by or within the air handling system; and an insulative polyurethane foam within the internal chamber, wherein the insulative polyurethane foam is configured to insulate the air handling system, wherein the tray includes a base and outer walls, wherein the base and outer walls are distinct from the insulative polyurethane foam, and wherein the tray is connected to the single housing. ### Claim 17 (depends on 16) The assembly of claim 16, wherein the at least one sound passage section comprises at least one perforated sheet secured to at least one of the first and second plates. ### Claim 18 (depends on 16) The assembly of claim 16, wherein the at least one sound passage section is integrally formed into at least one of the first and second plates.
