Intermediate member for a stethoscope, wherein the intermediate member comprises - an input connection for a first stethoscope part, which introduces sound from a stethoscope head, - an output connection for a second stethoscope part, which leads sound to at least one ear interface (45a-b), - a connecting channel between the input connection and the output connection, which can lead sound from the input connection to the output connection, and - an electronic amplifier arrangement, comprising a) a microphone arrangement for recording sound received via the input connection, b) a loudspeaker arrangement for delivering sound to the output connection, c) an electronic amplifier with which signals picked up by the microphone arrangement can be amplified and fed to the loudspeaker arrangement, d) an energy storage for supplying the electronic amplifier arrangement with electric power, wherein the microphone arrangement and the loudspeaker arrangement are arranged on the connection channel in such a way that the microphone arrangement is closer to the input connection than the loudspeaker arrangement, wherein the microphone arrangement has a directional characteristic, so that the microphone arrangement registers sound coming from the side of the input connection more strongly than sound coming from the side of the loudspeaker arrangement and the output connection, wherein the loudspeaker arrangement has a directional characteristic, so that sound emitted by the loudspeaker arrangement is conducted more strongly to the side of the output connection than to the side of the microphone arrangement and the input connection, and wherein there is a closure device which is switchable between an open position and a closed position, wherein the closure device in the closed position closes the connection channel between the microphone arrangement and the loudspeaker arrangement, and in the open position the connection channel between the microphone arrangement and the loudspeaker arrangement is open, characterized in that the connecting channel between the input connection and the output connection runs along a longitudinal axis, and in that the microphone arrangement and the loudspeaker arrangement comprise directional channels (14a, 15a) which branch off from the connecting channel both in the open position and in the closed position of the closure device and run inclined to the connecting channel. -
