Pulmonology Breath Sounds

Egophony

Egophony is the finding that when the patient says E it sounds like A or “ah”, like the bleating of a goat. The mechanism is thought to be that the consolidated lung better transmits low frequency sounds and filters out some of the high frequency sounds, leading to this change in the sound. Egophony may also be heard over a thin band of compressed lung over a pleural effusion.
