There exists a direct proportional relation between the acoustic impedance of the tympanic membrane and static pressure in the external acoustic duct. This relation forms the basis of the UM-01 device which enables the acoustic impedance to be determined and allows it to judge from its magnitude on the condition of the sound-conducting sector of the auditory analyser. The device is simple to handle and does not require any balancing of the measuring portion in the circuit.
鼓膜的声阻抗与外耳道中的静压之间存在正比关系。这种关系构成了UM - 01设备的基础，该设备能够测定声阻抗，并能根据其大小判断听觉分析仪传音部分的状况。该设备操作简单，电路中的测量部分无需任何平衡操作。
