The sound waves travel as pressure waves through the oval window inside the inner ear, then return through the round window, and are finally dissipated through the ear canal.
The ear is a complex organ that allows us to hear. Sound waves enter the outer ear and travel down the ear canal until they reach the eardrum. The eardrum vibrates in response to the sound waves, and these vibrations are transmitted to the three tiny bones in the middle ear. The three bones in the middle ear amplify the vibrations and transmit them to the oval window in the inner ear.
The oval window is described as a membrane that separates the middle ear from the inner ear. When the oval window vibrates, it creates pressure waves in the fluid-filled inner ear and these pressure waves travel through the cochlea, a snail-shaped structure in the inner ear. The cochlea is lined with tiny hair cells, which vibrate in response to the pressure waves.
