| Abstract: | Equipment for recording respiratory and voice sounds from the human body surface is described. An acoustic detector based on an electret microphone and equipped with a stethoscopic head and remote two-channel amplifier of signals of acoustic detectors is designed. The acoustic detectors (preamplifier) are connected to the microphone (linear) input of the remote sound card connected to the personal computer, which processes signals with the use of specialized and universal software. |
