If you literally mean can you listen to your own heartbeat then maybe not. But, if you mean can a person's heartbeat be heard without an instrument, then the answer is yes. In the early days doctors rested their ear against the patient's chest to hear the heartbeat. A doctor in those puritanical times, realizing ladies did not like him to press his ear to their bosoms, rolled up a tube of paper, pressed it to their bosom and put his ear to the other end. This was the origin of the stethoscope.
