Abstract

9912. Brown, S. G. July 7. Subaqueous sound signals.-In apparatus for receiving or emitting sound or compressional waves, a device for transferring wave energy from one medium to another, as from water to air, consists of a long tapering rod mounted to vibrate longitudinally, the base reacting with the denser medium. As shown, a rod A is attached to a diaphragm a covering an orifice in a ship's skin B, and used to receive subaqueous signals. The rod is supported by a casing C containing water, and is insulated from the casing and ship's skin by rubber rings a<2>, a<1>. The smaller end may carry a microphone or other sound-detector D. The rod may be of any cross-section and taper, and need not be straight; preferably, it is made to taper according to a logarithmic law. The rod may be hollow at the base, as at a<3>, or entirely hollow, and contain water. In the latter case, the water may fill a diaphragm chamber carried by the smaller end of the rod and supporting a microphone. Wood, vulcanite, and cellulose acetate are mentioned as suitable materials for the rod. The rod is selective in its action, a rod of given material and proportions transmitting certain frequences imperfectly. For emitting subaqueous sounds, the smaller end of the rod A is vibrated, for example by means of an electric buzzer, telephone diaphragm, or electrically-operated tuning-fork.
