Egophony
Sign in to saveEgophony (British English, aegophony) is an increased resonance of voice sounds heard when auscultating the lungs, often caused by lung consolidation and fibrosis.

It results in a high-pitched nasal or bleating quality in the affected person's voice.

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. It results in a high-pitched nasal or bleating quality in the affected person's voice.
==Technique== While listening to the lungs with a stethoscope, the patient is asked to pronounce the modern English (more generally, post-Great Vowel Shift) long-E vowel sound.
