During the late 1960s and throughout the 1970s, the U.S. Navy conducted a series of ocean acoustic measurement exercises to support development of systems and techniques to detect nuclear submarines. The exercises and most of the technical documentat

In October 1975 a measurement exercise designated CHURCH OPAL was done in the northeast Pacific Ocean to assess undersea acoustic noise and propagation phenomena. In 2003 the 10 days of deep ocean multiple hydrophone recordings during CHURCH OPAL wer

An analysis is given of a solion acoustic pressure detector which has a direct current output proportional to the logarithm of the pressure input. An approximate method is used which avoids solving the Navier‐Stokes equation describing the fluid fl

An audiofrequency underwater transducer utilizing a folded exponential horn has been designed, developed, and tested. The horn is driven by a lead zirconate titanate piezoelectric bimorph driver, producing a sound output of 74 db re 1 dyne/cm2 at 1 y

The reflection of sound pulses from corrugated surfaces has been a problem of interest in architectural acoustics for some time. This problem has been examined by simulating the process on a digital computer. The simulation has been carried out in su

An interesting variation of the classical problems involved in synthesizing desired sonar transducer beam patterns is to examine the effects caused by missing acoustic radiating elements. Beam patterns were calculated for a multi‐element circular a

At the last two meetings of the Acoustical Society of America, some results were presented of a digital‐computer simulation of the scattering of sound pulses from slatted surfaces. It was shown that the computed directivity pattern of the scatterin

In acoustics, particularly underwater sound, it is often desirable to know the statistics of the amplitude distribution resulting from a finite time average of a rectified broadband noise (broadband in the sense that the bandwidth is comparable to or
