The small bone called the stirrup, one of the ossicles, exerts force on a thin membrane called the oval window, transmitting sound pressure information into the inner ear.

这块称为锤骨的骨片，是三块听小骨之一，对称为椭圆窗的薄膜施加力，将声压信息传递到内耳。

The inner ear can be thought of as two organs: the semicircular canals which serve as the body's balance organ and the cochlea which serves as the body's microphone, converting sound pressure impulses from the outer ear into electrical impulses which are passed on to the brain via the auditory nerve.

内耳可以看作是两个器官：半规管，作为身体的平衡器官，以及耳蜗，作为身体的麦克风，将外耳传来的声压信号转化为电信号，并通过听神经传递给大脑。

The basilar membrane of the inner ear plays a critical role in the perception of pitch according to the place theory.

根据位置理论，耳内基底膜在音调感知中起着关键作用。

The Semicircular Canals

半规管

The semicircular canals, part of the inner ear, are the body's balance organs, detecting acceleration in the three perpendicular planes. These accelerometers make use of hair cells similar to those on the organ of Corti, but these hair cells detect movements of the fluid in the canals caused by angular acceleration about an axis perpendicular to the plane of the canal. Tiny floating particles aid the process of stimulating the hair cells as they move with the fluid. The canals are connected to the auditory nerve.

半规管是内耳的一部分，是身体的平衡器官，用于检测三个垂直平面中的加速度。这些加速度计利用类似于耳石器的毛细胞，但这些毛细胞检测的是由于绕 canal 平面法线方向轴的角加速度所引起的管内流体的运动。微小的漂浮颗粒在随流体运动时帮助刺激毛细胞。这些管子连接到听神经。
