A behind-the-ear hearing aid is provided with an electric/acoustic transducer unit with a loud-speaker housing ( 53 ), in which there is a loud-speaker membrane 54. The housing ( 53 ) is spring-mounted in a capsule ( 59 ) in such a way that the capsule ( 59 ) and the loud-speaker housing ( 53 ) define an intermediate space (U<SUB>53</SUB>). The front (R<SUB>1</SUB>) of the membrane ( 54 ) is connected to the acoustic output (S) of the hearing aid, while the back (R<SUB>2</SUB>) is coupled to the intermediate space (U<SUB>53</SUB>) via coupling holes ( 55 ).
