Cost-effective noise reduction techniques for historic buildings can be accomplished affordably and without altering the structure's historic status. Techniques include adding sashes to existing historic windows, replacing windows with visually compatible acoustic units, and using jamb extensions to accommodate manufacturers' standard window units. Wood-truss roofs can be insulated from noise on the interior through the addition of a light-gauge metal framing support with alternating layers of gypsum board, plywood, and batt insulation. Ventilation solutions include a unique over-the-sill air intake system that functions as an acoustic baffle and visually spares a historic facade from random louver punch-throughs. Acoustically rated doors and vestibule construction address noise reduction at entry ways. At an example installation, sound levels were reduced by 12 dB, and speech interference levels were reduced by 18–23 dB. Continuous use is the best method for preservation of historic buildings. Noise reduction, sensibly applied, gives a historic structure occupational viability in the modern world.
