Abstract: A method for manufacturing a transmitter/receiver (1) for transmitting/receiving acoustic waves, which method comprises at least the following steps: placing a transmitting and/or receiving layer (10) in or on an inner housing (2) in a manner such that a side of the inner housing is at least virtually sealed off by the transmitting and/or receiving layer, providing at least a first material (16) in a space enclosed by the inner housing, which space is adjacent to the transmitting and/or receiving layer, providing an outer housing (4) around an inner housing, which outer housing surrounds the inner housing at least partly after provision, and providing a second material (20) between the inner housing and the outer housing, characterized in that upon provision of the second material, through pouring, the second material runs in a vacuum, between the inner housing and the outer housing for the purpose of manufacturing a fixed connection between the inner housing and the outer housing.
