This increase in sound exists because sound travels faster and thus with lower loss of intensity through liquid or solid ("fluid mass" or "solid mass," respectively, in the lung) versus gaseous (air in the lung) media. Whispered pectoriloquy is a clinical test typically performed during a medical physical examination to evaluate for the ...
Bronchophony may be caused by a solidification of lung tissue around the bronchi – which may indicate lung cancer – or by fluid in the alveoli, which may indicate pneumonia. However, it may also have benign causes, such as wide bronchi. As such, it is usually an indication for further investigation rather than the main basis of a diagnosis.
For example, in whispered pectoriloquy, the person being examined whispers a two syllable number as the clinician listens over the lung fields. The whisper is not normally heard over the lungs, but if heard may be indicative of pulmonary consolidation in that area. This is because sound travels differently through denser (fluid or solid) media ...
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]
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.

In order to listen to the lungs from the back the patient is asked to move their arms forward to prevent the scapulae (shoulder blades) from obstructing the upper lung fields. These fields are intended to correlate with the lung lobes and are thus tested on the anterior (front) and posterior (back) chest walls.
