This test, along with bronchophony and whispered pectoriloquy, is used to assess for consolidation in the lung.
Performing the Test
- Ask the patient to repeat "EEEE" out loud and at moderate volume
- Listen to the posterior lung fields with the the diaphragm of the stethoscope, noting any asymmetry
In normal lungs, the transmitted "EEEE" will be long and muffled. Egophony is positive if the "EEEE" shifts to sound more like "AAY" and may indicate consolidation.
