Mass and Stiffness Impact on the Middle Ear and the Cochlear Partition

摘要: Mass and stiffness affect on the peculiar characteristics of transmission middle ear distinctive behavior cochlear mechanics. Applying principle mass stiffness, band-pass characteristic transfer function has been explained. The greatest ear, approximately 24-29 dB, is observed at 1-2 kHz in both cat human species. However, lower frequencies, was disturbed by primarily due to cavity. At higher bones. Several examples, such as an acoustic reflex, otitis media, otosclerosis are discussed. For understanding traveling wave basilar membrane, different place tuning certain stimulus contrastingly shaped membrane duct, structural physical whole partition were reviewed terms changing width, mass, from base apex. Being about ten times wider, more massive, one hundredfold stiffer than apex, nature absorb high-frequency energy changes fluid pressure declines toward Consequently, cochlea, high frequencies stimuli decoded while low apex cochlea. Due these partition, direction also proved be fashion base-to-apex always.
