His research areas were the physiology of muscles (anaerobic muscle contraction ), the central nervous system ("flow theory" of the conduction of excitation in nerves), the vegetative system, the sensory organs and the physics and physiology of speech sounds ( acoustic phonetics ; he coined the term formant ).

Hermann is known for the Hermann grid named after him . He described this optical illusion in 1870. Ewald Hering made this optical illusion known; therefore it is also called the herring grid . Walter Ehrenstein emphasized Hermann's priority in 1941.
