Respiratory sounds, also known as lung sounds or breath sounds, are the specific sounds generated by the movement of air through the respiratory system. [1] These may be easily audible or identified through auscultation of the respiratory system through the lung fields with a stethoscope as well as from the spectral characteristics of lung sounds. [2]
Crackles are caused by the "popping open" of small airways and alveoli collapsed by fluid, exudate, or lack of aeration during expiration. Crackles can be heard in people who have pneumonia , atelectasis , pulmonary fibrosis , acute bronchitis , bronchiectasis , acute respiratory distress syndrome (ARDS), interstitial lung disease or post ...
Egophony (British English, aegophony) is an increased resonance of voice sounds [1] heard when auscultating the lungs, often caused by lung consolidation and fibrosis.It is due to enhanced transmission of high-frequency sound across fluid, such as in abnormal lung tissue, with lower frequencies filtered out.
They may be described as fine (soft, high-pitched) or coarse (louder, low-pitched). These are the result of alveoli opening due to increased air pressure during inspiration. Common causes include congestive heart failure. [22] Stridor a high-pitched musical breath sound resulting from turbulent air flow in the larynx or lower in the bronchial ...
Pectoriloquy is the increased resonance of the voice through the lung structures, so that it is clearly comprehensible using a stethoscope on the chest. It usually indicates consolidation of the underlying lung parenchyma. [1] Types include egophony and bronchophony. [2]

Normally, the sound of the patient's voice becomes less distinct as the auscultation moves peripherally; bronchophony is the phenomenon of the patient's voice remaining loud at the periphery of the lungs or sounding louder than usual over a distinct area of consolidation, such as in pneumonia.
The three types of ingressive sounds are lingual ingressive or velaric ingressive (from the tongue and the velum), glottalic ingressive (from the glottis), and pulmonic ingressive (from the lungs). The opposite of an ingressive sound is an egressive sound, by which the air stream is created by pushing air out through the mouth or nose. The ...
