An intermediate link set for a stethoscope, comprising two intermediate links (42; 42a; 42b) each for arrangement between an ear-hook end and an earpiece of the stethoscope, the intermediate links (42; 42a; 42b) each having - an input channel for incoming sound and an input connector of the input channel for connection to the ear-hook end, and - an output channel for outgoing sound and an output connector of the output channel for connection to the earpiece, - a microphone arrangement for recording the incoming sound from the input channel, - an amplifier arrangement for electronically amplifying the incoming sound,and - a loudspeaker arrangement for outputting the outgoing sound into the output channel, characterized in that the intermediate links (42; 42a; 42b) are each designed such that - the input channel or an input-side sound chamber, into which the input channel opens, and the output channel or an output-side sound chamber, into which the output channel opens, are acoustically separated from one another by a fixed intermediate wall of the intermediate link (42; 42a; 42b), - the microphone arrangement is arranged axially at the end of the input channel and at least partially within a radial extension region of the input channel, - and the loudspeaker arrangement is arranged axially at the end of the output channel and at least partially within a radial extension region of the output channel. comprising two intermediate links (42; 42a; 42b) each for arrangement between an ear-hook end and an earpiece of the stethoscope, the intermediate links (42; 42a; 42b) each having - an input channel for incoming sound and an input connector of the input channel for connection to the ear-hook end, and - an output channel for outgoing sound and an output connector of the output channel for connection to the earpiece, - a microphone arrangement for recording the incoming sound from the input channel, - an amplifier arrangement for electronically amplifying the incoming sound,and - a loudspeaker arrangement for outputting the outgoing sound into the output channel, - an input channel for incoming sound and an input connector of the input channel for connection to the ear-hook end, and - an output channel for outgoing sound and an output connector of the output channel for connection to the earpiece, - a microphone arrangement for recording the incoming sound from the input channel, - an amplifier arrangement for electronically amplifying the incoming sound,and - a loudspeaker arrangement for outputting the outgoing sound into the output channel, characterized in that the intermediate links (42; 42a; 42b) are each designed such that - the input channel or an input-side sound chamber, into which the input channel opens, and the output channel or an output-side sound chamber, into which the output channel opens, are acoustically separated from one another by a fixed intermediate wall of the intermediate link (42; 42a; 42b), - the microphone arrangement is arranged axially at the end of the input channel and at least partially within a radial extension region of the input channel, - and the loudspeaker arrangement is arranged axially at the end of the output channel and at least partially within a radial extension region of the output channel. - the input channel or an input-side sound chamber, into which the input channel opens, and the output channel or an output-side sound chamber, into which the output channel opens, are acoustically separated from one another by a fixed intermediate wall of the intermediate link (42; 42a; 42b), - the microphone arrangement is arranged axially at the end of the input channel and at least partially within a radial extension region of the input channel, - and the loudspeaker arrangement is arranged axially at the end of the output channel and at least partially within a radial extension region of the output channel.
