A bstract The purpose of this investigation was to correlate the decay of vibration of glass bars with their chemical composition. The moduli of decay of four commercial glasses were determined by a photographic method which employed an oscillograph to provide a graphic representation of the audible tone emitted by the bars when they were set in vibration. By using bars of identical cross section and different lengths, data were obtained showing the relation of length to modulus of decay. The effect of disannealing on the modulus of decay was also investigated.
