mammals. The innermost bone is the stapes, or “stirrup bone.” It rests against the oval window

oval window

The oval window is the intersection of the middle ear with the inner ear and is directly contacted by the stapes; by the time vibrations reach the oval window, they have been amplified over 10 times from what they were when they contacted the tympanic membrane, a testament to the amplifying power of the middle ear.
