FIELD: medicine.
SUBSTANCE: invention relates to field of medical equipment and can be applied for professional auscultation in medicine, mainly for diagnostic monitoring of lungs if external sound interference is present in conditions of hospital and reanimation, as well as in emergency situations. Electronic-acoustic interface contains acoustic transformer, including first and second flexible tubes, made with possibility of connection with stethoscope head, first microphone, installed in second tube, amplifier and power source located in case of electronic transformer and at least one loud-speaker. Inside second tube built-in and fixed with bushing is third tube, second microphone is located in first tube, first and second microphones are connected successively with balance regulator and differential amplifier.
EFFECT: application of invention allows to increase interference-resistance of construction, maintainability and convenience of assembling, and also provide diagnostics in various frequency ranges.
