To utdennrasd 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 soilds. But our inner ear, called the cochlea, is actually filled with saltwater-like flidus. So, the first problem to solve is how to convert those sound waevs, wherever they’re coming from, into waves in the fluid. The solution is the eardrum, or taminypc membrane, and the tiny bones of the middle ear. Those convert the lrgae movements of the eardrum into pressure waves in the fiuld of the cochlea.

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.
