Method for testing air permeability of horn tympanic membrane

The invention discloses a method for testing the air permeability of a horn tympanic membrane. The method comprises the following steps: firstly, putting a tympanic membrane 1 into a first positioning hole 21 in a lower tympanic membrane positioning mold 2; further, a middle hole sealing gasket 3 is plugged into the center of the first positioning hole 21, and an inner ring of the drum membrane 1 is pressed; further, a driving device 4 pushes an upper press-fit sealing mold 5 to move downwards to be matched with the lower tympanic membrane positioning mold 2 to tightly press the outer ring of the tympanic membrane 1 and the mesopore sealing gasket 3, so that a first sealing cavity 20 and a second sealing cavity 50 are formed in the two sides of the tympanic membrane 1; furthermore, the first sealing cavity 20 and the second sealing cavity 50 are connected with a flow meter 203 and an air source respectively, the first sealing cavity 20 and the second sealing cavity 50 are connected with a first pressure senso
