Experimental Listening Devices

Hayes collection, hydrophone

The task at hand in designing "tubes" for detecting submarines was to build a device that could detect both the sound source and its bearing relative to the chaser. Additionally, the device had to pick out the sound of enemy submarines from an array of noises including the engines of surface vessels. Many different configurations were tested, some of which are shown in this set. Thanks to Roy Manstan and the Harvey Hayes Family Archives for the images.
