Abstract

A method for manufacturing an ultrasonic transducer for use in a fluid medium. At least one piezoelectric transducer element is joined directly or indirectly to at least one matching member for promoting vibration coupling between the piezoelectric transducer element and the fluid medium. A matching member is used which has at least one porous molding of a polymer.
