A single 11 by 25 inch sheet of dense black open-cell foam with a peel-and-stick backing, meant to be bonded onto the metal housing of an outdoor AC compressor to dampen hum and shell vibration. It needs no glue or tools, and the matte black face sits quietly against typical outdoor units. It is a vibration damper, not a full enclosure: it works on the panel it touches, so it helps most on small compressors and shared walls, less on loud units that need barrier mass or a proper cover. Rival acoustic panels offer similar foam at larger sizes or with foil facings; this one is sized for a standard compressor top or side panel.

This self-adhesive acoustic foam sheet is made to reduce noise from outdoor cooling compressors. It mounts directly over the metal housing shell to cut compressor hum and vibration feedback. No glue or power tools are needed.
The sheet is made of dense open-cell foam that absorbs mechanical vibrations. A pressure-sensitive adhesive backing attaches it to the housing right away. The matte black finish blends in with outdoor equipment.
Each sheet measures 11 by 25 inches, sized for standard compressor fit.
