Highlights
JOHANNES MtiLLER (1801-1858) had shown the medical world that there were certain laws of voice-production which could be demonstrated in experiments with the larynges of corpses
Scientists who held against MULLER'S EXPERIMENT the fact that he had gained his results from experiments with the heads of bodies and not with living individuals, were directed to experiments demonstrating subglottal pressure "in vivo" i.e. in patients who, after tracheotomy had to wear a cannula
These experiments were supposed to show, similar to MULLER'S findings, that voice pitch depends upon the interaction of vocal fold tension and air-pressure
Summary
JOHANNES MtiLLER (1801-1858) had shown the medical world that there were certain laws of voice-production which could be demonstrated in experiments with the larynges of corpses. In these experiments he showed that (1) the pitch of the tone artificially produced depended on the tension of the vocal folds. If the air-stream remained constant and the tension of the folds of the same larynx was increased, the pitch of the tone went up.
