Anatomy of Human Ear
Human hearing is a complex and fascinating sensory ability that allows us to perceive sounds in our environment. Sound waves travel through the air and enter our ears, where they are converted into electrical signals that our brains interpret as sound.
Outer Ear: The outer ear includes the pinna (the visible part of the ear) and the ear canal. Its primary function is to collect sound waves and direct them into the ear canal.
Middle Ear: The middle ear contains the eardrum (tympanic membrane) and three small bones called ossicles (the malleus, incus, and stapes). When sound waves reach the eardrum, it vibrates, causing the ossicles to amplify and transmit the vibrations to the inner ear.
Inner Ear: The inner ear consists of the cochlea, a spiral-shaped organ filled with fluid, and the auditory nerve. When vibrations from the middle ear reach the cochlea, they stimulate tiny hair cells lining its surface. These hair cells convert the vibrations into electrical signals, which are then sent along the auditory nerve to the brain.
Conductive hearing loss
This type of hearing loss results from diseases or disorders that limit the transmission of sound through the outer or middle ear. This hearing loss can usually be treated medically or surgically. In some cases,a hearing instrument is also indicated and can provide sufficient hearing improvement.
Sensorineural hearing loss
This type of hearing loss affects the inner ear or neural pathways. This type of loss usually occurs due to damages to the hair cells or to the fine nerve endings inside the cochlea. This leads to reduced perception of sound intensity and quality. This type of hearing loss is usually compensated with a hearing instrument that amplifies sound to overcome the decrease in hearing sensitivity.
Mixed hearing loss
This type is the combination of both type of losses mentioned above. Treatment options for this type of impairment include both medical intervention and hearing instruments.
Hearing loss can occur due to various factors that affect the auditory system.
Here
are the primary causes:
Ear discharge.
Middle ear problems
Increased pressure of the Inner ear fluid.
Noise.
Ototoxic drugs.
Injury to the ear or head
Presbycusis- Hearing loss due to aging.
01If you answer is "yes" to more than two of the following questions, you should have your hearing checked.
Do you have a problem hearing over the telephone?
Do you hear better through one ear than the other when you are on the telephone?
Do you have trouble following the conversation with two or more people talking at the same time?
Do people complain that you turn the TV volume up too high?
Do you have trouble hearing in a noisy background?
Do you have dizziness, pain, or ringing in your ears?
Do you find yourself asking people to repeat themselves?
Do family members or coworkers remark about your missing what has been said?
Do many people you talk to seem to mumble (or not speak clearly)?
Do you misunderstand what others are saying and respond inappropriately?
Do you have trouble understanding the speech of women and children?
Do people get annoyed because you misunderstand what they say?
02Generally, a good number of patients with conductive hearing losses can be helped surgically or medically. The remaining require hearing aids.
A hearing aid is a miniature amplifier. The microphone picks up sound signals and converts them into electrical signals, which are then amplified and directed to a receiver. The signals are reconverted back into audible sound which will be sent to the ear.
