Abstract
Measurements of the sound radiation patterns in water from
the flexural vibrations of a clamped-edge steel disk have been
made and are compared with the results of theoretical calculations
made by Alper and Magrab (Journal of Acoustical Society
of America, Vol. 48, Number 3, pp. 681-691, 197 0) for the two
lowest order circularly symmetric modes of disk vibration.
Although some differences were expected and were found due
to the experimental condition which only approximated the assumptions
made in the theory, it was found that 'the major features
of the measured patterns agreed reasonably well with the theoretical
pattern.
The results have applicability to the design of sound
source which could be used in underwater tracking of vehicles
on a test range.
