Hearing loss can affect anyone at any age, and understanding its type and symptoms is crucial for early treatment. One of the most common types is conductive hearing loss, which occurs when sound cannot efficiently travel through the outer or middle ear to reach the inner ear. This article explains what conductive hearing loss is, its main symptoms, and why prompt diagnosis is important.

What Is Conductive Hearing Loss?
Conductive hearing loss happens when there is a problem in the outer ear, ear canal, eardrum, or middle ear (ossicles) that prevents sound waves from reaching the inner ear (cochlea).
In simple terms, the “conduction” of sound is interrupted — just like when a pipe is blocked and water can’t flow through properly.
This type of hearing loss can be temporary or permanent, depending on the underlying cause, and it is often treatable through medical or surgical procedures.
Common Causes of Conductive Hearing Loss
Several conditions can block or reduce sound transmission, such as:
-
Earwax buildup (cerumen impaction)
-
Fluid in the middle ear due to infection or allergies
-
Perforated (torn) eardrum
-
Otosclerosis (stiffening of the middle ear bones)
-
Ear infections (otitis media or externa)
-
Foreign objects lodged in the ear canal
-
Malformation of ear structures (present from birth)
Key Symptoms of Conductive Hearing Loss
People with conductive hearing loss may notice one or more of the following:
-
Reduced Hearing Ability
-
Sounds may seem muffled, faint, or blocked.
-
You may feel like your ear is “plugged” or “underwater.”
-
-
Sudden or Gradual Hearing Changes
-
Hearing may drop suddenly (for example, after a cold or shower).
-
In some cases, the loss develops slowly over weeks or months.
-
-
Fullness or Pressure in the Ear
-
A sensation of heaviness or pressure inside the affected ear.
-
-
Ear Pain or Discomfort
-
Often associated with infections or fluid buildup in the middle ear.
-
-
Tinnitus (Ringing or Buzzing Sounds)
-
You may hear noises in the affected ear even when there’s no external sound.
-
-
Better Hearing Through Bone Conduction
-
You might hear your own voice louder or clearer than external sounds.
-
-
Hearing Better in One Ear Than the Other
-
Conductive loss often affects one ear more than the other, leading to imbalanced hearing.
-
Diagnosis
An audiologist or ENT specialist can diagnose conductive hearing loss using:
-
Otoscopy: Visual inspection of the ear canal and eardrum.
-
Audiometry: Hearing tests to measure sound thresholds.
-
Tympanometry: Checks eardrum and middle ear function.
These tests help determine if the hearing loss is conductive, sensorineural, or mixed.
Treatment Options
-
Medical Treatment
-
Antibiotics or antifungal medications for infections.
-
Removal of earwax or foreign objects.
-
Treatment for allergies or sinus-related ear congestion.
-
-
Surgical Treatment
-
Repair of perforated eardrum (tympanoplasty).
-
Middle ear reconstruction or stapedectomy in cases like otosclerosis.
-
-
Hearing Aids or Bone Conduction Devices
-
If medical or surgical correction isn’t possible, hearing aids effectively amplify sound to bypass the blockage.
-
Conclusion
Conductive hearing loss is often temporary and treatable, especially when diagnosed early. Recognizing the symptoms — such as muffled sounds, ear fullness, or pain — can help you seek prompt professional care and restore your hearing clarity.
If you notice any of these symptoms, don’t ignore them — visit a qualified audiologist or ENT specialist for proper evaluation and treatment.
