Evaluation of the computational validity of the image model in predicting the sound field in a wedge-shaped layer using acoustical reciprocity

Abstract

Computer models based on the method of image were used to investigate and calculate the pressure amplitude distribution in wedge-shaped (tapered) water layer overlying a fast, absorbing bottom. The pressure amplitude of the field was generated and compared at reciprocal positions of source and receiver. The results showed that the ratio of pressure was larger when the position of source receiver was closer to the bottom and nearer the apex.
