Abstract
This paper will describe the development of a passive source localization device to enhance the ability of scuba divers to locate acoustic sources. The device consists of a hat that is worn by the scuba divers and provides a distinct null in the observed acoustic field when the diver is facing the acoustic source. Tests were carried out in a 25‐ft‐deep, 198‐ft‐diam tank at the EPCOT Center in Orlando, FL on 25 subjects. The results of these tests show that there is a clear improvement using this device, which is comfortable to wear and suitable for most applications.
