The ears are like antennae. They pick up signals from various directions. The complicated structure of ear processes the signals and passes them on to brain where they’re interrupted. At the end of ear canal, sound waves actually hit the eardrum, which is a thin membrane between middle and outer ear. Eardrum is connected directly to hammer bone.
Hammer bone along with stapes and anvil are smallest bones in human body. They pass on mechanical vibrations of ear drum into inner ear. Stapes transmit vibrations through oval window to inner ear. In this manner, sound waves arrive in cochlea that’s filled up with the fluid.
Sound moves along in form of travelling wave via fluid-filled cochlea, through hair cells, which change mechanical vibrations into the nerve impulses that are passed to brain. It is this point from where we hear. If there arises any problem in any of the parts through hearing process takes place, hearing loss takes place.
Often misunderstood as an insignificant problem, hearing loss can considerably impact an individual’s quality of life. If it is left untreated, it can lead to a wide range of issues, which can make the simplest activities look daunting. Some of the common complaints are:
