Its 3 parts are (1) auricle or pinna (2) external acoustic canal and (3) the tympanic membrane.

这 3 个部分分别是：（1）耳廓；（2）外耳道；（3）鼓膜。

The inflammatory response creates mucosal oedema and increase middle ear discharge, eventually leading to tympanic membrane perforation.

炎症反应导致粘膜水肿，中耳分泌物增多，最终导致鼓膜穿孔。

On Audiometric testing: 1) Otoscopy: Reddish hue on tympanic membrane called " schwartz sign" .

1）耳镜检查：鼓膜呈红色，称为“施瓦茨症”。

Sound waves traveling down the auditory canal eventually collide with the tympanic membrane, which you probably know as the eardrum.

沿着听道传播的声波最终会与鼓膜相撞。

The solution is the eardrum, or tympanic membrane, and the tiny bones of the middle ear.

解决方案是鼓膜或鼓膜，以及中耳的小骨头。

But once the sound wave passes through the ear canal, it reaches your eardrum, or tympanic membrane.

但是一旦声波通过耳道，它就会到达您的耳膜或鼓膜。

The tympanic cavity focuses the pressure of sound waves so that they're strong enough to move the fluid in the inner ear.

鼓膜腔集中声波的压力，这样它们就足够强大，可以移动内耳中的液体。

" And then I'll probably wanna look in the ears, " kind of see how the tympanic membrane is looking.

“然后我可能想看看耳朵， ”看看鼓膜的样子。

Therefore, to see the tympanic membrane, the pinna has to be pulled upwards, backwards and laterally so as to bring the two parts in alignment.

为了看到鼓膜，耳廓必须向上、向后和横向拉，以便使两部分对齐。

External Acoustic (Auditory) Canal It extends from the bottom of the concha to the tympanic membrane and measures about 24 mm along its posterior wall.

外耳道从外耳门向内延伸至鼓膜，长度约 24 毫米。
