The heartbeat can be measured in several different ways, the most common being to count the beats to get the heart rate - beats-per-minute. This can be done with a watch and a finger on an accessible blood vessel, an artery.
Or you can take an electro cardiogram, where an electronic instrument is attached by leads to the chest and picks up and registers the tiny electric impulses that controls the heart.
Or you can use a stethoscope and listen to the beats.
Or you can use an ultrasound imager, see the movement, the flow and the heart rate.
A stethoscope is used to listen to the heart and lungs.

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.
