Abstract
Why do animals have intense troubles mainly in the basal turn of their cochlea by sound exposure and by ototoxity ? The author thought that the protein in cells had an important relation to this subject. A silicon model of hair cells was made and was poured three kinds of solutions of protein. And the ionization of the protein and its denaturation were checked by giving strong energy of oscillation to them like the similar idea of photoelectric effect. As the result, as for the protein liquid, the increase of volts was noted just after the model was exposed to sound. About 3 hours later, the figure decreased gradually. From this phenomenon, the author presumed that the protein in sensory cells became a factor of the stimulation by receiving strong energy conversely. Low-percent protein liquid had less effect by sound.
Because temperature absorbs the energy of sound, it was noticed that there was little increasing tendency in the albumin, the plasmanate and the pan-amin.
As for pH, there is no change or a little tendency to increase in the albumin, the plasmanate and the pan-amin, and the significant change of the osmotic pressure was found in the albumin about 30 hours later.
