The whispered pectoriloquy test is similar to bronchophony, but not so much egophony.

Similar terms are bronchophony and whispered pectoriloquy.

Bronchophony is a type of pectoriloquy.

Other tools used in auscultation include listening for egophony, whispered pectoriloquy, rales, rhonchi or wheezing.

The only difference between whispered pectoriloquy and bronchophony is the volume at which the patient is asked by the clinician to repeat "ninety-nine" or "baseball."

Whispered pectoriloquy refers to an increased loudness of whispering noted during auscultation with a stethoscope on the lung fields on a patient's torso.

That is, in whispered pectoriloquy, the repeated words are whispered at low volume, and in bronchophony, they are spoken at normal volume.

Somewhat related, bronchophony, a form of pectoriloquy is a conventional respiratory examination whereby the clinician auscultates the chest while asking the patient to repeat the word "ninety-nine".

Other terminology for sounds that may be auscultated in the thorax include crackles, wheezes, pleural rubs, pulmonary murmurs, egophony, whispering pectoriloquy, vocal fremitus and rales.

Here, the patient's voice (or whisper, as in whispered pectoriloquy) can be heard more clearly when there is consolidation, as opposed to in the healthy lung where speech sounds muffled.

Whispered pectoriloquy is a clinical test typically performed during a medical physical examination to evaluate for the presence of lung consolidation, which could be caused by cancer (solid mass) or pneumonia (fluid mass).
