A Transducer to Reduce Standing Waves

Pagination or Media Count:
An underwater sound transducer having a directivity pattern rotated 10 degrees from the normal to the face of the transducer has been constructed and tested for use in making c-w acoustical measurements in a small tank. Standing waves between the faces of the two instruments involved were thus eliminated or substantially reduced. Other uses may suggest themselves to the reader who is interested in underwater sound measurements on reflecting and absorbing surfaces without resorting to a pulsing technique.
