Answer:-There are three tiny bones in this area — the malleus, incus and stapes. (Healthcare providers refer to these three bones as the ossicles.) They transfer sound vibrations from your eardrum to your inner ear. Your middle ears also house the eustachian tubes, which help equalize the air pressure in your ears. The main function of the middle ear is to carry sound waves from the outer ear to the inner ear, which contains the cochlea and where sound input can be communicated to the brain. Sound waves are funneled into the outer ear and strike the tympanic membrane, causing it to vibrate. The middle ear is an air-filled cavity that sits between the tympanic membrane [3] and the inner ear. The middle ear also consists of three tiny bones called ossicles [4], the round window [5], the oval window [6], and the Eustachian tube [7].
