In one example, we describe a method and system which consist of a small rubber attachment which can be slipped onto the chest piece of any stethoscope. We show designs, configurations, and descriptions of different finger guard designs. This reduces drastically or eliminates completely the background sound picked up from the fingers of the user/physician, which may interfere with diagnosing the physiologic sound picked up from the patient. In one example, we describe a method and system for Stethoscope Attachment, Auscultation Device. The device is a small attachment which can fit to any stethoscope. It connects between the removable chest-piece and tubing. The device houses a computer and sensor (e.g., membrane) which can receive incoming sound waves and analyze, or compare them to stored waveforms to categorize and analyze the incoming sound, to diagnose or recognize or classify the auscultated sound. Other variations are also shown.
