Aegophony

  • Aegophony is a type of vocal resonance obtained on auscultating the chest.
  • The patient is asked to say one-one-one or ninety-nine repeatedly and the lung fields are auscultated
  • Normally the resonant sound rather than the exact syllables is heard by the examiner, the character and intensity of which depends on the sound of the patient, the condition of the lungs and chest wall
  • Above the level of a pleural effusion or in some cases of consolidation, the sound heard has a nasal or bleating character
    • This finding is known as Aegophony (Egophony)
  • The word Aegophony is derived from the Greek work (aix, aig-) for goat, due to the bleating character of the sound
