reportActive / Technical Report | Accession Number: ADA053115 | Open PDF

Abstract:

This memorandum presents the design and performance characteristics of a hydrophone that is intended for low level noise measurements in the frequency range from 100 to 3000 cps. It is constructed of four barium titanate cylinders, each six inch O.D. by two inches long by 0.2 inch thick, that are mounted coaxially and mechanically isolated from each other and the end-plates.
