Excerpt: ... Another variety which remains to be noticed, is called the friction sound. It is produced by the two surfaces of the pleura rubbing against each other when roughened by false membranes, or tubercular deposition. It is not unlike the rumpling of parchment, is usually jerking, and made up as it were of a succession of crackling noises. If heard exclusively at the summit of the lungs it might lead to the suspicion of tubercular pleurisy, but in the general way, is the index of pleurisy in progress of cure. II. Auscultation of the Voice. 1. The resonance of the voice is variously modified by disease. It is said to be bronchial (broncophony) when much more powerful than natural. Broncophony is remarkable for intensity, extent, fixity, and permanence. It almost always coincides with bronchial respiration. It commonly betokens pulmonary induration, proceeding from pneumonia or tubercles, but is also met with in dilatation of the bronchial tubes, and in some cases of pleurisy. 2. The tremulous resonance (oegophony) is of a rather shrill and jerking character. It seems as if the individual spoke at times with a counter between the teeth and lips. It is generally heard on one side in the lower half of the depression below the scapular ridge, but may shift its position as the patient moves about. It almost uniformly coincides with feebleness or absence of the vesicular murmur at the base of the chest. If heard on one side and fever be present, it is evidential of pleuritic effusion; if-on both sides without fever, but with general dropsy, of hydrothorax. When it originates during inflammation of the lungs, and shifts its position as above stated, pleuropneumonia exists. 3. The cavernous voice (pectoriloquy). Here, the vocal vibrations seem as it were concentrated in...
