For clarifying the function of tympanic muscles in human beings, the experimental fatigue of acoustic sensation and the acoustic reflex of the tympanic membrane were observed by means of measuring the retraction grade of the tympanic membrane. The retraction grade of the tympanic membrane and fatigue during continuous volley in persons without experience of shooting were observed with the following results.<BR>1). The classification of the acoustic reflex of the tympanic membrane was attempted through the findings of the tympanic membrane.<BR>2). The interrelation between the type of audiogram in fatigue and the acoustic tympanic reflex was clearly made.<BR>3). In tympanic muscles in good condition and in the normal chain mechanism of the ossicles, the conduction of higher tone becomes better by the change of conductive system including the tympanic membrane to the tone and becomes the factor of remarkable loss in higher frequency or of c3 dip. However, the speech area is protected by the slight lesion in the low or middle frequency range.<BR>4). Where the acoustic reflex of the tympanic muscles is bad, it is possible to lose the hearing acuity even in the lower frequency area.<BR>5). Considering the latency of this reflex the protective function of the inner ear to momentary intense sound is doubtful, but it is evident from this experiment that the tonus of this muscle acts protectively in the time of long exposure to the intense sound.
