Abstract:

Sound pressure measurements in the frequency range zero to 8000 cycles per second were made on the USS Quillback, SS 424 on 6 November 1950 and recorded on disks. The recordings were played back through a series of octave and half-octave filters. The sound output in these channels is shown graphically in the enclosures. Author
