The present technique for measuring the airborne sound insulation of wails and floors, involving measurements in 16 one-third octave bands, is tedious and expensive. The method provides more information than is needed for most purposes, and is more suited to research. Several investigators have pro

Concrete panels (floor slabs and wails) have been experimentally studied to determine the airborne sound insulation of those with cylindrical circular hollows, compared to solid concrete panels of the same surface density. Both room-size and small-scale models have been investigated. Probable sound-
