Sound-absorptive panel for an air handling system

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.

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.
