The process of listening to the various sounds in the body is called Auscultation. This process also aids in lung sounds audio so that diagnosis can be made. A stethoscope is used in this process by the attending doctor to listen to either vesicular or bronchial breathing. With vesicular breathing the sounds can be heard at the back and chest since this is where the lungs are located. Bronchial sounds are heard along the trachea or the collarbone and are done through the shoulder or chest. This process of listening to lung sounds audio is very important and it requires proper preparation to avoid making any mistakes.
Then listen to the sounds of the chest from side to side and also begin this process from the bottom to the top. After this, listen at both sides from the collarbone and stop at the pectoral muscle. Also listen to the sounds at the rib cage and the breast bone. After you are through with the process, interpret what you have found out. A patient that has large airways will give out sounds that are high pitched. With bronchial sounds, you will also hear high pitched sounds but both the inspiration and expiration will be of equal length and you will also notice in case the patient pauses in between the breathing. Vesicular sounds will be low pitched and inspiration will be longer compared to expiration. You will not be able to hear any sounds when the patient pauses for breath.

When you identify types of lung sounds like adventitious, they will have wheezing, rhonchi, rales and stridor. Rales lung sounds also known as crackles are very high pitched and not continuous. These sounds will occur when there is air within the closed spaces and they make bubbling or clicking sound. They can either be coarse, moist or fine sounds. Rhonchi sound is also alike snoring sounds. This occurs when air is blocked within the air waves and is traveling roughly. When the airwaves become narrow during exhalation, then the wheezing sounds occur. A wheeze sound that is produced during inspiration is called stridor. This occurs when air is trapped in the throat or trachea.
If you suffer with abnormal lung sounds, then do not worry, these problems will be diagnosed and the correct medication administered.
