ABSTRACT:
An energy generator of a Sonobuoy is overlapped by a sleeve or chimney guiding gas bubbles given off by the generator to a sufficient distance from an electro-acoustic transducer of the Sonobuoy, to prevent such bubbles from coming into contact with the transducer under heaving effects. The result is suppression of unwanted noise produced by the contact between the bubbles and the transducer.
