MUSICAL SOUNDS UNDER WATER
All the world has learned something of the hydrophane-tlie instrument which bo detected by the vibrations they set up in the water. Less is known about the wonderful experiments carried out in connection with this work, in the production of sound under water. the method ultimately adopted was to blow a jot of condensing steam from a nozzle on to a diaphragm under water. This resulted in the production of a soft musical note which could be heard by means of a hydrophone up to a distance of eleven nautical miles Themanner in which the sound is produced is closely akin to the “singing” of a kettle before it boils; the repeated collapsing of bubbles of steam on coming into contact with cold water sets up vibrations which, under certain conditions, are rapid enough to give a musical note These oxperimen s are of great scientific interest, and may well prove of practical value in commercial navigation as well as in naval operations.
