The analysis of the uncertainty of the determination of the noise source direction in the aquatic environment is presented in this paper. The type A uncertainty of the bearing algorithm was determined on the bases of multiple measurements of the hydroacoustic pressure by means of the TC4032 type hydrophones and the GPS device data. The influence of the non-linearity of the amplitude-frequency characteristic on the uncertainty of the determination of the noise source direction, was also described. The influence of water density, electromagnetic disturbances and irregular noises on the final uncertainty was determined. On the bases of the determined uncertainty components the uncertainty budget, of the determination of the angle showing the direction from which hydroacoustic waves are coming, was prepared.
