Bronchophony vs. Egophony — What's the Difference?

Bronchophony is the abnormal transmission of sounds from the lungs or bronchi. Bronchophony is a type of pectoriloquy.

Egophony (British English, aegophony) is an increased resonance of voice sounds 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.

(pathology) A modification of the voice sounds observed in auscultation of the chest; used as a diagnostic test

(medicine) A bleating sound sometimes observed in patients with various lung conditions

A modification of the voice sounds, by which they are intensified and heightened in pitch; - observed in auscultation of the chest in certain cases of intro-thoracic disease.

The sound of a patient's voice so modified as to resemble the bleating of a goat, heard on applying the ear to the chest in certain diseases within its cavity, as in pleurisy with effusion.
