Its function is to transmit sound from the air to the ossicles inside the middle ear, and then to the oval window in the fluid - filled cochlea . Hence, it ultimately converts and amplifies vibration in air to vibration in fluid . The malleus bone bridges the gap between the eardrum and the other ossicles . </P> <P> Rupture or perforation of the eardrum can lead to conductive hearing loss . Collapse or retraction of the eardrum can cause conductive hearing loss or cholesteatoma . </P>
