Whispered pectoriloquy
Whispered pectoriloquy refers to an increased loudness of whispering noted during auscultation with a stethoscope on the lung fields on a patient's back.[1]
Usually sounds of this volume would not be heard when whispered. It is a test performed during a medical physical examination to evaluate for the presence of lung consolidation, which could be caused by cancer or pneumonia.

The test is similar to the test for bronchophony and egophony. In bronchophony, the physician often asks the patient to say “ninety-nine” or "baseball" while listening over the lung fields: the sound will be louder in areas where consolidation is present.
History
The choice of "ninety-nine" is the unfortunate result of a literal translation. The test was originally described by a German physician who used the phrase "neun und neunzig" (pronounced [ˈnɔʏnʊntˈnɔʏntsɪç]), which he chose because it contains diphthongs, calculated to cause maximum vibration of the chest. The translation, "ninety-nine", has fewer vowels and is less effective in evoking the phenomenon.[2] Better phrases in English include "toy boat”, "Scooby Doo", and “blue balloons".
