Abstract A prefabricated structural wall panel for the modular construction of soundproof enclosures containing layered compartments of shallow depth with the central compartment divided longitudinally into a pair of intake and exhaust ventilation ducts located edge to edge, and these ducts are separated by perforate sheet metal walls from the adjoining interior and exterior compartments of the panel which contain sound absorbing thermal insulation. An air inlet is installed near the lower end of each duct and an air outlet near its upper end; and a fan is enclosed within the air intake system. Fresh air enters near the lower end of the exterior of the panel and is forced upwardly through the intake duct by the fan to the upper part of the panel from which it is discharged into the enclosure, while the air being exhausted from the enclosure enters a conduit near the bottom of the interior face of the panel and passes up through the exhaust duct for discharge through a conduit communicating with the upper exterior face of the panel.
A modular acoustic ventilating structural panel containing layered compartments which comprises a series of at least four substantially parallel sheets of rigid material of substantial area and spaced to form relatively shallow compartments containing sound absorbing material and adjoining each side of a relatively shallow central compartment of relatively large side wall area, an imperforate member dividing said central compartment into separate and substantially unobstructed intake and exhaust air ducts, an inlet air conduit adjacent one end of said panel connecting said intake air duct with the exterior face of said panel, an inlet air conduit adjacent said end connecting said exhaust air duct with the interior face of said panel, an outlet air conduit adjacent the opposite end of the said panel for connecting said intake air duct with said interior face of the panel, an outlet air conduit adjacent the opposite end of said panel for connecting said exhaust air duct with said exterior face of said panel and means for forcing air through one of said ducts.

Claim 3
Dependent Claim
21 words
A panel according to claim 1 in which the side walls of said central compartment are constructed of perforate sheet material.
Claim 4
Dependent Claim
14 words
A panel according to claim 2 in which said air conduits have perforate walls.
Claim 5
Dependent Claim
20 words
A panel according to claim 1 in which a fan located within said panel forces air through said intake duct.
Claim 6
Dependent Claim
41 words
A panel according to claim 1 in which said rigid material is sheet metal disposed to avoid an uninterrupted metal lining extending continuously along the entire path of air flow through said intake air duct and the connecting air conduits thereof.
Claim 7
Dependent Claim
39 words
A panel according to claim 5 in which said air conduits are connected with said intake air duct through apertures in said duct of larger size than said conduits to avoid metal-to-metal contact between said duct and said conduits.
