Audiology is the branch of science that deals with hearing loss and related problems. The main objective of audiology is to prevent, identify, evaluate, diagnose, and treat hearing problems, balance disorders, and related conditions.
Audiology combines knowledge from different fields such as physiology, anatomy, physics, and psychology to develop effective treatment plans for the patients.
Causes of Hearing Problems
Hearing loss is a common problem that affects people of all ages. There are different types of hearing loss, based on their causes. Some of the common causes of hearing loss include:.
Noise Exposure
Loud noises can damage the hair cells in the inner ear causing hearing loss. This type of hearing loss is referred to as noise-induced hearing loss (NIHL).
People who work in noisy environments such as factories, mining, construction, and music industries are at higher risk of developing NIHL.
Aging
Hearing loss due to aging is called presbycusis. It is a gradual loss of hearing that occurs with aging. The hair cells in the inner ear start to deteriorate over time, leading to hearing loss.
Presbycusis is one of the most common types of hearing loss among older adults.
Disease or Infection
Hearing loss can result from diseases or infections that affect the ear. Some of the common diseases that can cause hearing loss include Meniere’s disease, otosclerosis, and autoimmune disorders.
Genetics
Sometimes hearing loss can be inherited from parents. In such cases, the condition is referred to as genetic hearing loss. Genetic hearing loss can be present at birth or develop later in life.
Trauma
Hearing loss can also result from trauma to the ear or head. Trauma can cause damage to the ear drum, middle ear bones, or the cochlea (inner ear). Explosions, car accidents, and falls are some of the common causes of trauma-related hearing loss.
Hearing Tests
If you suspect you have a hearing problem, the first step is to consult an audiologist. The audiologist will perform a series of tests to evaluate your hearing and determine the type and degree of hearing loss. Some of the common hearing tests include:.
Pure-tone Audiometry
This is a test that measures your ability to hear sounds of different frequencies and volumes. The test is usually carried out in a soundproof booth, and the patient wears headphones connected to an audiometer.
The audiologist plays sounds of different frequencies and volumes, and the patient responds by indicating when they can hear the sounds.

Speech Audiometry
This test evaluates the patient’s ability to understand speech. The audiologist will play words at different volumes, and the patient responds by repeating the words.
The results of this test will determine the patient’s ability to communicate effectively with others.
Tympanometry
This test evaluates the movement of the eardrum in response to changes in air pressure. The test can detect problems in the middle ear such as fluid buildup, blockage of the Eustachian tube, and damage to the middle ear bones.
Treating Hearing Problems
The treatment of hearing problems depends on the underlying cause and the degree of hearing loss. Some of the common treatment options include:.
Hearing Aids
Hearing aids are devices that amplify sounds and improve the patient’s ability to hear. The audiologist will recommend the best type of hearing aid based on the patient’s hearing loss, lifestyle, and budget.
Cochlear Implants
Cochlear implants are electronic devices that are implanted in the inner ear and provide direct stimulation to the auditory nerve. Cochlear implants are used to treat severe to profound hearing loss in people who do not benefit from hearing aids.
Middle Ear Implants
Middle ear implants are devices that are surgically implanted in the middle ear to treat conductive hearing loss. The implant transmits sound vibrations directly to the middle ear bones, bypassing the damaged part of the ear.
Hearing Rehabilitation Programs
Hearing rehabilitation programs are designed to help patients cope with their hearing loss. These programs teach patients communication strategies, lip-reading, and other skills that can improve their ability to communicate with others.
Preventing Hearing Loss
Preventing hearing loss is much easier than treating it. Some of the things you can do to protect your hearing include:.
Protect Your Ears from Loud Noises
Avoid exposure to loud noises or wear hearing protection if you have to work in noisy environments. Earplugs and earmuffs are effective in reducing the intensity of loud noises.
Maintain Ear Health
Avoid inserting objects such as cotton swabs or hairpins into your ears. These objects can damage the ear canal and increase the risk of infection. Also, avoid exposure to cigarette smoke and other irritants that can damage the ear tissues.
Get Regular Hearing Tests
Regular hearing tests can help detect hearing loss early and prevent further damage. If you work in a noisy environment, it is recommended to get hearing tests annually to monitor your hearing health.
