(( ;ii-\ , Ewart.) It is stronger in persons with deep,low-pitched voices, the vibrations not being so rapid, and is more distincttherefore in males than in females. It is felt more distinctly in persons with thin chest-walls. Fremitus Is weaker in people with thick chest-walls and large mammary glands which interfere with the transmission of fremitus. The fremitusis not distinct in children because the vibrations are too rapid. Vocal Fremitus in Disease. The vocal fremitus may be increased; itmay be diminished; or it may be absent. Increased Vocal Fremitus. Vibrations are transmitted to thehand with greater force by a consolidated lung than by one containingair. Fremitus is increased consequently in pneumonia, tuberculosis,. Transverse section of thorax: A, consolidation—pneumonia, vocal fremitus increased,B, pleural effusion, vocal fremitus absent. (Original.) hemorrhagic infarct, and tumor. (See Fig. 156.) The fremitus, however,may be absent in the rare cases of pneumonia in which the large tubesare occluded by exudate. Fremitus is increased when the lung is com-pressed above a pleuritic exudate. It is also increased over a cavity,which acts as a resonator. Diminished Vocal Fremitus. Anything intervening between thelung and the surface of the chest and interfering wdth the conduction ofthe vibrations diminishes the fremitus. The fremitus therefore is dimin-ished over a thickened pleura and over a thin layer of pleural effu-sion. The fremitus is also lessened when on account of diminution in PERCUSSION IN DISEASES OF THE LUNGS AND PLEURA. 483 the calibre of the bronchi the columns of air in them are smaller, as inbronchitis, in emphysema
