An underwater microphone is attached to a claw piece support fixed to a mounting board via anti-vibration rubber, and a plurality of swingable claw pieces are attached, and an elevating member is screwed into the lower end threaded part of a rotary rod that passes through the mounting board. A mounting part is provided in which the end of the connecting pipe is connected to the upper part of the claw piece, one end of the connecting pipe part is attached to the mounting plate of the mounting part, a meter setting part is attached to the other end of the connecting pipe part, and the meter setting part is attached to the other end of the connecting pipe part. A rotating member is provided with a gear fixed to the inner end that meshes with a gear fixed to the end of the rotating rod, and a turning disk is fixed to the outer end, the end is opened on the surface of the claw piece support, and the rotating member is connected. Connect the conduit extending inside the pipe section to the water pressure gauge of the meter setting section, and pass the cord whose end is fixed to the underwater microphone through the cord insertion hole of the vibration-proof rubber, through the mounting board, and through the inside of the connecting pipe section. A circuit is attached to the guide board within the housing of the meter setting section, and includes a digital display with a volume adjustment knob provided in the meter setting section, an indicator meter, and a headphone jack, and a branch path is provided from the conduit. A sound pressure/water pressure measuring instrument for mounting on a fire hydrant, consisting of an on-off valve installed on the branch road and an air bleed pipe connected to the branch road connected to the air bleed channel on the mounting board.
