Abstract

Investigations on the physiology of the ear have always been limited by the lack of a method of determining the function of hearing in the animal. Most of the classic research on the organ of hearing has been carried out heretofore by means of clinical observations and histopathologic examinations (for example, Bezold's investigations on otosclerosis). A reliable method of estimating the function of hearing not only is a necessity from the standpoint of experimentation on animals but also would be of definite value if it could be adapted to clinical use and so obviate the necessity of depending on the statements of the patient as to hearing function. It is, therefore, understandable that several attempts have been made to use reflexes as an indicator of hearing. Cemach,¹ who studied them intensively named several motor responses which in his opinion are certain indicators of cochlear function. According to Cemach
