Sound: An Elementary Text-book for Schools and Colleges

    Abstract

    In the second edition of Dr. Capstick's text-book of sound, a chapter has been added giving an outline of some of the more important applications of acoustics to military operations during the war of 1914–18. The author is not very successful in conveying in the fewest possible words a clear idea of the apparatus employed, and his descriptions would have been improved by the use of diagrams. It must, however, be pointed out that some of the diagrams in the earlier chapters are by no means perfect. In Fig. 95 the pendulum would quickly damage the mercury cup, and it is doubtful whether the Bell telephone in Fig. 99 would have been recognised by its inventor. The granular transmitter, inadequately illustrated on page 222, does not serve in this primitive form as a suitable microphone for use in a hydrophone. The author has obviously made a slip when he says that in signalling under water the sound is received by a submerged microphone similar to a receiving telephone. In spite of some defects the volume will serve a useful purpose as a class-book for schools.
