Sound Insulation and the Apartment Dweller
The Journal of the Acoustical Society of America, 1964 Most of the existing sound-insulation requirements are based on experience with traditional construction, and this is reflected in the shape of the standard grading curve. Since nontraditional constructions frequently have quite different sound-insulation characteristics, the desired shape of insulation curve, i.e., the relative importance of the ...
