Claim 0:
1. A pressure coupling chamber (1), comprising;
at least one hydrophone (2),
at least one hydrophone adapter (9) intertwined with the hydrophone (2),
a fastener for sealing the hydrophone (14) by sealing between the hydrophone (2) and the hydrophone adapter (9),
At least one thread adapter (7) located at the top of the hydrophone adapter (9),
a fastener for sealing the thread adapter (13) to provide sealing between the hydrophone adapter (9) and the thread adapter (7),
a fastener for fixing the thread adapter (8) to the hydrophone adapter (9),
a pressure coupling chamber body (4) located between the thread adapter (7) and a reference receiver unit sealing tube (5),
an internal volume of the pressure coupling chamber (A) formed between the pressure coupling chamber body (4) and the hydrophone,
at least two acoustic sources (6), located and evenly spaced around the pressure-sensitive active surface of a hydrophone element and mounted to the pressure coupling chamber body (4) symmetrically,
at least one thread pin (11) and an acoustic cap (10) in the pressure coupling chamber body (4), and fixed with a fasteners for fixing (15) to the acoustic source cap (10),
microphones (LS1 or LS2) as a reference receiver unit (3),
at least one reference receiver unit (3) fixed to the upper part of the hydrophone (2) with fasteners for sealing the reference receiver unit (12) and sealed with the sealing tube (5), and
air medium in the internal volume of pressure coupling chamber (A), that is not subjected to a separate pressurization externally.
