Abstract :
One of the most destructive forces likely to damage jet planes or missiles is sound. For testing products to be used in such devices, Goodyear Aircraft Corp. has constructed a huge noise-maker to duplicate exactly the sound vibrations that can, at 150 db of sound, damage or even mutilate a piece of steel. The sound test chamber is part of an environmental testing facility at Goodyear built at an over-all cost of more than $1 million.
