Abstract: The invention relates to a hydrophone housing. The housing comprises an outer casing with an exterior shape being in close contact with sediment when buried therein and having a deflectable wall part. Solid material partly fills the casing to define an outer chamber behind the deflectable wall part, a cavity shaped so that an inner chamber is defined immediately surrounding a hydrophone sensing element held therein, and a first duct for liquid flow communication between the outer chamber and the cavity or an internal volume of the hydrophone sensing element. Thereby, a hydraulic coupling is provided so that an acoustic pressure causing small radial displacements of outer surface of the housing will, via liquid in the first duct, cause large radial displacements of the hydrophone sensitive element. The area of the deflectable wall part is much larger than the area of the sensitive element so that only small displacements of the housing are required to cause large displacements at the hydrophone sensing element.

Abstract translation: 本发明涉及一种水听器壳体。 壳体包括外壳，其外部形状在埋入其中时与沉积物紧密接触并具有可偏转的壁部分。 固体材料部分地填充壳体以限定可偏转壁部分后面的外室，空腔成形为使得内室被定义成立即围绕保持在其中的水听器感测元件，并且第一管道用于在外室和 空腔或水听器感测元件的内部容积。 因此，提供液压联接器，使得通过第一管道中的液体导致壳体的外表面的小的径向位移的声压将引起水听器敏感元件的大的径向位移。 可偏转壁部分的面积比敏感元件的面积大得多，因此仅需要壳体的较小位移才能在水听器感测元件处引起大的位移。

Abstract: There is provided a solid seismic streamer cable for use in seismic surveying in marine environments. The streamer is characterized by a buffer layer 2 which is provided with a cut-out 50 and a sensor element arranged in the cut-out 50. There is also provided an associated hydrophone for integration into the seismic streamer cable. The hydrophone is characteristic in a split-element sensor base 10, 11 being suited for efficient mounting into the cut-outs 50 of the seismic cable. There is also provided an associated accelerometer for integration into the seismic streamer cable. The accelerometer is characteristic by a split-element sensor base 30, 35 for being efficiently arranged into the cut-outs 50 of the seismic cable. A method of producing a seismic streamer cable according to the invention incorporating a hydrophone or accelerometer according to the invention is also provided.
