Tremors or vibrations in an area of the body, detected by palpating (feeling) with the ?ngers or the hand or by auscultation (listening). The procedure is most commonly used when examining the chest and assessing what happens when the patient breathes, coughs or speaks. This helps the doctor to diagnose whether disorders such as ?uid in the pleural cavity or solidi?cation of a section of the lung have occurred.
Friction fremitus is a grating feeling communicated to the hand by the movements of lungs or heart when the membrane covering them is roughened, as in PLEURISY or PERICARDITIS. Vocal fremitus means the sensation felt by the hand when a person speaks; it is increased when the lung is more solid than usual.

The air carrying the voice produced in the LARYNX passes through the throat, mouth and nose. The shape and size of these structures will in?uence the timbre of the voice, or vocal resonance. This will vary from person to person and even within an individual; for example, with a cold.... vocal resonance
(vocal cords) the two folds of tissue which protrude from the sides of the *larynx to form a narrow slit (glottis) across the air passage (see illustration). Their controlled interference with the expiratory air flow produces audible vibrations that make up speech, song, and all other vocal noises. Alterations in the vocal folds themselves or in their nerve supply by disease interfere with phonation.... vocal folds
