The Whispered Voice Sounds.—Whispering is the result of articulatespeech in which the glottis plays no part. Over the normal chest thewhispered voice is scarcely audible, since whispering does not set upsympathetic vibrations of the thoracic wall.

We receive the impression that the source of the soundis very near to the end of the stethoscope, or as if someone were talking directly intothe latter. Some authorities speak of a normal and a pathologic bronchophony,using the former term as synonymous with vocal resonance. THE VOICE SOUNDS 135. Fig. 109.—Htdhothorax.
