Acoustic attenuation in 1 in. diam by 15 in. long rods cast from double base propellant mixture is measured for longitudinal excitation from 500 to 14,000 cps in discrete steps by successive use of quarter and half-wave resonance, and pulse techniques; data are observed to give reasonable fit to quality factor of 5.5; room temperature propellant sound velocity is about 810 m/sec, giving effective Young's Modulus = 1.1×1010 d/sq cm; pertinence to unstable combustion processes of solid propellant rockets.
