It is best heard in the lower anterior lungs and lateral chest, during both inspiration and expiration. Potential causes include tuberculosis and pneumonia. The sound quality is considered a harsh grating or creaking. The pleural rub sound results from the movement of inflamed pleural surfaces against one another during chest wall movement. Fine crackles sound quality is like hair rubbing near the ear and may be heard in congestive heart failure and pulmonary fibrosis. Coarse crackles sound quality is low-pitched and moist it may be heard in pulmonary oedema and bronchitis. Crackles can be further categorised as coarse or fine. It is commonly heard in the bases of the lung lobes during inspiration. The cause of crackles can be from air passing through fluid, pus or mucus. ![]() The sound crackles create are fine, short, high-pitched, intermittently crackling sounds. It may be heard in asthma, emphysema and chronic bronchitis.Ĭrackles are also known as alveolar rales. It is commonly heard in the lungs during expiration. Alternately, what we often refer to as rhonchi is the sonorous wheeze, which refers to a deep, low-pitched rumbling or coarse sound, as air moves through tracheal/bronchial passages in the presence of mucus or respiratory secretions.

The sound of a wheeze is a high-pitched, continuous musical sound. It’s typically loudest over the anterior neck, as air moves turbulently over a partially-obstructed, upper airway. Stridor may be heard in conditions such as croup and foreign body obstruction. During expiration, the sound intensity can diminish somewhat. These sounds are low to moderate sound intensity (volume) with a low-pitch (200-600 Hz) and with a rustling quality. High-pitched, squeaky sound: Called stridor or laryngomalacia. Croup is not a common infection in newborns. The cause of this sound is generally the partial obstruction of the larynx or trachea. Vesicular lung sounds are the most common auscultated sounds, usually heard over most of the chest wall. This may be a sign of croup, an infection of the larynx, trachea and bronchial tubes. ![]() Stridor is a continuous, high-pitched, crowing sound heard predominantly on inspiration.
