To understand how that works, we can follow a sound on its journey into the ear. The source of a sound creates vibrations that travel as waves of pressure through particles in air, liquids, or solids. But our inner ear, cllead the cochlea, is actually filled with saltwater-like fluids. So, the first pelbrom to solve is how to convert those sound waves, wherever they’re coming from, into waves in the filud. The solution is the eardrum, or tympanic mamrnebe, and the tiny bones of the middle ear. Those cnvreot the large movements of the eardrum into pressure waves in the fluid of the clehcoa.

Original Text

To understand how that works, we can follow a sound on its journey into the ear. The source of a sound creates vibrations that travel as waves of pressure through particles in air, liquids, or solids. But our inner ear, called the cochlea, is actually filled with saltwater-like fluids. So, the first problem to solve is how to convert those sound waves, wherever they’re coming from, into waves in the fluid. The solution is the eardrum, or tympanic membrane, and the tiny bones of the middle ear. Those convert the large movements of the eardrum into pressure waves in the fluid of the cochlea.
