Sudden vs Gradual Hearing Loss: When to Seek Help

Types of Hearing Loss

Three types of hearing loss can be seen in people of all ages and understanding them can help in effective diagnosis and treatment:

Conductive Hearing Loss

Conductive hearing loss occurs when there is a problem with the outer or middle ear that prevents sound from being conducted to the inner ear. Some common causes include:

• Ear infections
• Fluid in the middle ear
• Blockages such as earwax or foreign objects
• Abnormal bone growths in the middle ear (otosclerosis)

Sensorineural Hearing Loss

Sensorineural hearing loss happens when there is damage to the inner ear (cochlea) or the auditory nerve. This type of hearing problem is usually permanent and can be caused by:

• Aging (presbycusis)
• Exposure to loud noises
• Certain medications that are toxic to the hearing
• Genetic factors
• Diseases such as Meniere's disease

Mixed Hearing Loss

Mixed hearing loss is a combination of conductive and sensorineural hearing loss. This means there may be damage in the outer or middle ear as well as in the inner ear or auditory nerve. Causes can include any combination of factors that contribute to both conductive and sensorineural hearing loss.

What Causes Hearing Loss?

There are several reasons for hearing loss; some common causes are:

• Age-related hearing loss (Presbycusis): A gradual loss is often seen in older adults
• Noise exposure: Long-term exposure to loud sounds damages the inner ear.
• Infections or illnesses: Some conditions like otitis media, meningitis or Meniere's disease can cause hearing loss.
• Genetic factors: If you have a close family member with hearing loss or a family history of genetic disorders that include hearing loss.
• Medicines: Some drugs, like ototoxic medicines, can damage the hearing nerve or inner ear structures.
• Trauma or injury to the head

What Are the Symptoms of Hearing Loss?

Recognizing hearing loss symptoms early can help you in its treatment and you can also take some preventive measures to control it:

• Gradual or sudden hearing difficulty
• Muffled or distorted speech and sounds
• Frequently asking others to repeat themselves
• Difficulty hearing in noisy settings
• Turning up the volume excessively
• Ringing in the ears (tinnitus)
• Children may show delayed speech development or inattentiveness in class.

Stages of Hearing Loss

Severity is categorized into stages based on how well a person can hear different sounds:

• Mild: Trouble hearing soft speech or whispers
• Moderate: Difficulty hearing regular conversation
• Severe: Can only hear loud noises; needs a hearing aid
• Profound: Little to no hearing; may benefit from implants

When to See a Doctor For Hearing Loss

Seek medical attention if you notice:

• Sudden hearing loss
• Ear pain or discharge
• Hearing changes in one ear

How is Hearing Loss Diagnosed?

Doctors use the following methods to determine what causes hearing loss:

• Otoscopic exam: Examines the ear canal and eardrum for abnormalities.
• Tympanometry: Tests the middle ear's function.
• Referrals to an ENT specialist or audiologists when needed
• Tuning Fork Test (Rinne Test): A tuning fork is used to compare air conduction and bone conduction of sound. The fork is placed against the mastoid bone and then near the ear canal. The patient indicates when they stop hearing the sound.
• Audiometer Test: The patient wears headphones and responds to various tones and volumes. Words are also presented at different decibel levels to assess hearing clarity.
• Bone Oscillator Test: A bone oscillator placed against the mastoid bone checks the function of the nerve transmitting sound to the brain.
• Newborn Screening: The otoacoustic emissions test (OAE) involves a probe in the outer ear to detect echo sounds. Lack of echo necessitates further testing to confirm hearing status.

Hearing Loss Treatment Options

Hearing loss treatment depends on the type and severity:

• Removal of wax blockage: Earwax is a reversible cause of hearing loss. Your doctor can remove earwax using suction or a small tool with a loop on the end.
• Surgical interventions: Some types of hearing problems can be treated with surgery, including abnormalities of the eardrum or hearing bones (ossicles). If you've had repeated infections with persistent fluid, your doctor may insert small tubes that help your ears drain.
• Hearing aids: If your hearing loss is due to damage to your inner ear, a hearing aid may be helpful. An audiologist can discuss the potential benefits of a hearing aid with you and equip you with a device. Open-fit aids are currently the most popular due to the fit and functionality offered.
• Cochlear implants: If you have more severe hearing loss and get limited benefits from conventional hearing aids, a cochlear implant may be an option. Unlike a hearing aid that amplifies sound and directs it into your ear canal, a cochlear implant bypasses damaged or non-functioning parts of your inner ear and directly stimulates the auditory nerve.

Natural Remedies for Hearing Loss

While there is no cure for hearing loss, natural remedies for hearing loss can support overall ear health:

• Healthy diet: Include foods that are good for your ears like fish and leafy greens, which are packed with healthy fats and antioxidants.
• Ear hygiene: Gently clean your ears, and avoid sticking anything into them.
• Lifestyle changes: Quitting smoking and managing stress can contribute to better ear health.
• Home exercises: Activities that focus on distinguishing different sounds might help if you have mild hearing loss.

How Can I Prevent Hearing Loss?

You may be wondering how you can prevent hearing loss. The following steps can help you in hearing loss prevention:

• Avoid loud noise: If you are in a noisy place, protect your ears with special earplugs.
• Monitor headphone use: Keep your music volume under 60% and take breaks to give your ears some rest.
• Manage chronic conditions: Conditions like diabetes and high blood pressure can impact your hearing.
• Regular hearing checkups: This is especially important for older adults or those at higher risk.

Complications of Untreated Hearing Loss

Untreated hearing loss can have several consequences. Understanding the complications of hearing loss includes:

• Cognitive decline: Research links hearing loss with a higher risk of dementia.
• Social isolation: It can be hard to communicate, which might cause you to withdraw from social situations.
• Depression and anxiety: Problems with communication can lead to feelings of depression and anxiety.

Hearing Loss and Its Effect on Speech & Communication

Hearing loss can seriously impact how people communicate, especially children:

• Children: They might struggle with learning to talk properly or may take longer to develop language skills.
• Adults: People who are facing hearing loss often find it difficult to understand communication, making life more difficult to communicate with friends, family, or at work.

Speech therapy can often help improve communication skills for those affected.
