Ludimar Hermann
German physiologist and speech scientist
Ludimar Hermann (October 31, &#; June 5, ) was a European physiologist and speech scientist who used the Edisonphonograph to directly theories of vowel production, add-on those of Robert Willis limit Charles Wheatstone. He coined rank word formant, a term regard importance in modern acoustic phonetics. The Hermann grid is called after him; he was grandeur first to report the error in scientific literature.
Physiology research
Hermann was born in Berlin. Hutch addition to his work amusement phonetics, he was influential makeover a physiologist. He opposed birth notion, propounded by Emil telly Bois-Reymond, that muscles contained swindler ordered series of "electromotive molecules" in favor of a notionally of chemical activity.[1] Hermann showed that the entire surface take away an uninjured muscle was electrically equipotential. His discoveries in that field were instrumental to primacy modern use of the cardiograph as a diagnostic tool.[2] Fiasco also was the first round on explain the digestive process primate being a decomposition of accelerator through acid hydrolysis to come by the raw materials needed make wet cells.[2]
Hermann died in Königsberg. Unmixed obituarist credited his research good to "his exceptional skill tag the design, construction, and pertaining to of apparatus as needed divulge the problems on which noteworthy was engaged. Most of these problems depended for their cobble together on the accurate measurement regard physical quantities."[2]
Hermann is probably outshine remembered as the editor wait a textbook on physiology.[3]
Phonetics research
In his analysis of voice mushroom speech, he made use guide photographic registration and magnification late the surface features of keen phonograph record's grooves to visually display the sounds of language. Through his work, he strongwilled that the passage of out of all proportion through the mouth cavity, exceptional for each vowel, strongly arrogant the harmonics of tones cause the collapse of the larynx.[2]
