    Types of Lung Sounds and Auscultation: An Overview (2025)

    Causes of Abnormal Lung Sounds

    Abnormal lung sounds can arise from various conditions affecting the respiratory system, each indicating different underlying pathologies.

    Here’s an overview of common causes associated with each type of abnormal lung sound:

    • Crackles (Rales): These sounds are often caused by fluid accumulation in the airways or alveoli, which can result from conditions such as pneumonia, heart failure, pulmonary fibrosis, or acute respiratory distress syndrome (ARDS).
    • Wheezes: Narrowing of the airways leads to wheezing, typically due to asthma, chronic obstructive pulmonary disease (COPD), bronchitis, or allergic reactions.

      It can also occur with foreign body aspiration.

    • Rhonchi: Caused by blockages to the larger airways by mucus or foreign bodies, leading to conditions such as chronic bronchitis or cystic fibrosis, where thick secretions are a hallmark.
    • Stridor: This high-pitched sound is indicative of upper airway obstruction and can result from croup, laryngeal edema, foreign object
