The frequency responses of TA-type hydrophones consisted of the electro-acoustic transducers made of barium titanate are described. The physical structures of the barium titanate trancducers of the TA-type hydrophones are short and thin hollow cylinders and they receive the acoustic energy of the underwater, only from their external surfaces and not from their internal and upper and lower surfaces of the cylinders. The theoretical responses of the TA-type hydrophones should have the flat characters between the values near to ω_2 and ω_1, where ω_2 is the natural angular velocity of the transducer while ω_1 is the angular velocity decided by ω_1R_2C_0=1, R_2 being the load resistance of the electric terminal of the hydrophone, and C_0 the static capacitance of the transducer. The results of the measurements, however, show that the frequency characteristics are apt to deviate from their theoretical values by the various defects of the constructions of the hydrophones, and there are many difficulties to obtain the flat responses especially on the rod shape TA-hydrophones
