Difference Between Incus And Stape

When a person with normal hearing hears the sound travels along the ear then bounces against the ear drum. The eardrum, the bones inside, and the cochlea vibrate and move thousands of tiny hairs inside the ear. When these hairs move an electrical response occurs. This electrical response goes to the hearing nerve and then it is send to the brain.

Basically how sound travels through the ear is a process of many steps. The sound waves are gathered by the pinna and then funneled into the meatus. Those waves then begin to vibrate the tympanic membrane which in turn hits against the malleus. The ossicle bones then vibrate like a chain reaction. The footplate will hit the oval window which triggers the fluid in the cochlea to move. The movement sways across the different hair cells creating impulses that are sent to the brain through the eighth cranial nerve.

The physiology of hearing starts with a vibration that occurs in the air which sends an acoustic signal to the ear drum. The signal is transduced into a mechanical signal that transmits through the inner ear and the cochlear nerve. Finally, the signal is

interpreted by sound receptors on the skin. This is transmitted to the brain for integration before

These sounds are heard on a daily basis are being bent and altered in order for us to properly hear them. Engineers have used trigonometry in many rooms, that are created for the production of music, to help the sounds that are transferred to bounce off the walls. This motion helps the sounds to balance which makes it easier

The middle ear consists of three bones, the malleus, incus, and stapes. The tensor teympany which is a muscle that attaches to the malleus bone, as well as the stapes which is a muscle which attaches to the stapes bone. These muscles help to keep the bone off of the membrane that they are on to stop damage from loud noise. And lastly there is a Eustachian tube which is the middle ear as well it helps with pressure.

The middle ear has three ossicles (tiny bones) the hammer, the anvil, and the stirrup that connect the middle ear to the inner ear. When sound enters your middle ear, it causes the ossicles to vibrate. These vibrations then move into the cochlea, which is filled with fluid. When the vibrations move the fluid that is in the cochlea, it stimulates tiny hair cells that respond to different frequencies of sound. After the tiny hair cells are stimulated, they direct the frequencies of sound into the auditory nerve, as nerve impulses. (ASHA 2013)

Hearing serves a crucial benefit for understanding the world around us. During the 1940’s, Dr. Ramsdell realized that hearing serves four crucial function; symbolically we are informed or entertained, aesthetically hearing is naturally pleasing, warningly we are alerted or prepared, primitively we are aware of our surroundings [1]. The ear is typically divided into three sections, used to simplify the hearing process. The first section, or the outer ear, is composed of the auricle (skin covered cartilage), the auditory canal, and the tympanic membrane (the outer layer of the eardrum). The middle ear section contains the eardrum, tympanic cavity, and the ossicles. These ossicles are three small bones often referred to as malleus (hammer),

The receiver is located adjacently to the transmitter on the other side of the skull and attaches to the electrode array. These two components are internal devices, with the electrode array going through the ear canal and cochlear. The receiver induces the electric impulses along the electrode array to stimulate the hearing nerve fibres in the inner ear. Signals are then sent via the hearing nerve to the brain and recognised as sound.

Sounds and speech are captured by a microphone and sent to the external speech processor. The processor then translates the sounds into electrical signals, which are then sent to the transmitting coil. These codes travel up a cable to the headpiece and are transmitted across the skin through radio waves to the implanted cochlea electrodes. The electrodes’ signals then stimulate the auditory nerve fibres to send information to the brain where it is interpreted as meaningful sound.

The bone-anchored hearing aid, or Baha, made by CochlearTM, is a bone conduction hearing aid. The Baha is usually fitted to those who cannot wear air conduction hearing aids. The Baha is typically fit to individuals with a conductive hearing loss, but can be fit to other hearing losses. Sound vibrations travel through the outer ear to the tympanic membrane, which moves the malleus, incus, and stables, also known as the ossicles. The footplate of the stapes moves against the oval window, which creates a wave in the fluid inside the cochlea. This results in a change in pressure of the basilar membrane, moving the hair cells, which send information through the auditory nerve to the brain. A conductive hearing loss is when sounds are not conducted

The ear is made up of three parts, the outer ear, the middle ear and the inner ear. The outer ear consists of the pinnae. Its function is to focus sound on the tympanic membrane. The middle ear is where the three ossicles are containes, the Malleus, Incus,
