Sound absorbing light fixture

A sound absorbing light fixture for use in a surface system of an enclosed interior, the light fixture comprising:

• a frame disposed in fixed relationship to the surface system, the frame having an interior rear surface and interior side surfaces extending outwardly from the rear surface to define a cavity;
• a light source disposed within the cavity;
• and
• a light diffuser disposed in fixed relationship to a front portion of the frame between the light source and the enclosed interior, wherein the installed light fixture enhances a sound absorption coefficient of the surface system for a predetermined frequency range of sound energy;
• and
• wherein the cavity is sized to attenuate sound energy within the predetermined frequency range.
