Simultaneously observe at 76 without any time delay and at the same time, video recording device 78
You can also record at. In addition, +500 to -500
The pressure change of daPa is not only appropriately changed, such as a sine wave, a sine wave, or a linear change, but also the pressure and the cycle are changed simultaneously to observe the movement of the eardrum 62. good.

幅な節約となる。(1) In the conventional method, the display of the dynamic characteristic measurement data of the middle ear and the observation of the movement of the eardrum 62 are performed separately, so that it takes a long time for the measurement. The observation of the findings of the tympanic membrane 62 and the measurement by the middle ear dynamic characteristic measuring circuit 71 can be performed at the same time, and the examination time is greatly saved.
