A kymograph consists of a revolving drum wrapped in paper on which a stylus draws to record measured changes of phenomena such as motion or pressure. [1] [2] The kymograph was initially a mechanical and hydraulic device, invented by German physiologist Carl Ludwig in the 1840s, and found its first use as a means to monitor blood pressure. The ...
Depth-kymography is the 3D display of the human vocal fold vibrations by measuring their vertical and horizontal movements simultaneously, using a specially designed 3D endoscope.
Accompanied by breath under lung pressure, the glottis and vocal folds move in an open-close motion. During the opening and closing, the process by which the vocal folds meet is referred to as phonation (non-technically called vocalization), which is the general function of how vocal sound is produced.
Kymograph, cased, Europe, 1880-1930 Washburn performed the experiment by fasting for several hours prior to each session, allowing his stomach to become empty and more likely to contract. After swallowing the balloon, which reached down into his stomach through the esophagus, Washburn had to sit still for prolonged periods while the pressure ...
1866 Henry Hyde Salter (1823-1871) added a kymograph to the spirometer in order to record time while obtaining air volumes. 1879 Gad J. published a paper entitled "Pneumatograph" that described a machine that allowed the recording of lung volume changes.
