The lub-DUB of the heartbeat is caused by the closing of two separate pairs of valves, in response to heart muscle contractions. Turbulent blood flow occurs as blood pushes against the valves.
The first sound is caused by the closing of atrioventricular valves (mitral valve, tricuspid valve) that separate the upper chambers (atria) and lower chambers (ventricles) of the heart, as blood enters the ventricles.
The second sound is caused by the closing of the semilunar valves at the exit of the ventricles (the right ventricle having pumped blood into the pulmonary artery and the left ventricle having pumped blood into the aorta).
There are other specific heart sounds that occur, usually as a result of problems with the function of the heart.
To perform auscultation, place a stethoscope on the skin to listen to sounds produced by the body, such as the heart, lungs, or intestines. Make sure the area is quiet, and be sure to listen for the specific sounds associated with each body system. Adjust the pressure of the stethoscope as needed to clearly hear the sounds.

A stethoscope is used to listen to the internal sounds of a human or animal. It can not only be used to listen to the lung and heart, but also the intestines and blood flow in the arteries and veins.
A doctor can tell if a person has abnormal breath sounds by listening with a stethoscope. This is often seen in people with COPD or asthma.

Barlow Syndrome
You do not "read" a stethoscope. It is a device that allows medical personnel to hear sounds within the body. Areas of sounds you can hear with a stethoscope include:heart soundsarterial sounds, such as a bruit (an abnormal sound)breath sounds (lungs)bowel sounds
When the doctor listens to the lungs through a stethoscope (ausculation), diminished or bronchial breath sounds may be heard. By tapping on the chest (percussion) while listening through the stethoscope, the doctor can often tell if the lung is collapsed
A stethoscope is an accoustic device that listens to sounds from within the body. It is used to hear heartbeats, or airflow in the lungs, or blood flow (as when determining the pulse rate).The stethoscope is a device (commonly used by doctors) to listen to heart and lung sounds. He places two earpieces into his ears and places the other part of the stethoscope on the chest and he will then be able to heart the sound of your heart and lungs.
