Conductive Hearing Loss

What Is Conductive Hearing Loss?

Conductive hearing loss occurs when sound waves do not efficiently transmit through your outer or middle ear, preventing them from reaching your inner ear. Conductive deafness is another name for this type of hearing loss. It can result from obstructions, infections, or irregularities in the structures of the ear. Patients with conductive hearing loss often experience muffled sounds, difficulty hearing faint or distant noises, and a decrease in overall sound volume.

Signs & Symptoms

Conductive hearing loss symptoms can manifest in different ways, affecting a patient's ability to hear and understand sounds.

Common conductive hearing loss symptoms:

  • Muffled hearing – Patients may feel that sounds are muffled or unclear, making it difficult to understand speech.
  • Difficulty hearing soft or distant sounds – You may struggle to hear faint noises or sounds from a distance.
  • Increased sensitivity to loud sounds – Patients may experience discomfort when exposed to loud noises.
  • Trouble understanding speech in noisy environments – Background noise can exacerbate hearing difficulties for patients with conductive hearing loss.
  • Ear pain or pressure – Depending on the underlying cause, you may experience pain or a sensation of pressure in the affected ear.


There are several causes of conductive hearing loss.

Conductive hearing loss causes include:

  • Earwax buildup – Excessive earwax can block the ear canal, impeding the passage of sound waves.
  • Ear infections – Inflammation and fluid buildup from infections can disrupt sound conduction in the middle ear.
  • Perforated eardrum – A hole or tear in the eardrum can hinder sound transmission and lead to hearing loss.
  • Abnormal growths – Benign tumors, such as cholesteatomas, may obstruct the ear canal or middle ear structures.
  • Eustachian tube dysfunction – Swelling or blockage of the eustachian tube can disrupt middle ear pressure, affecting sound conduction.
  • Malformation or damage to the middle ear bones – Abnormalities or trauma to the malleus, incus, or stapes can hinder sound transmission through the middle ear.

Risk Factors

Certain factors may increase your likelihood of developing conductive hearing loss.

Common risk factors include:

  • Frequent ear infections – Patients with a history of recurrent ear infections are more prone to developing conductive hearing loss.
  • Allergies – Allergic reactions can cause swelling in the eustachian tubes, leading to eustachian tube dysfunction and hearing loss.
  • Family history – Genetic factors may predispose you to middle ear abnormalities or other conditions that cause conductive hearing loss.
  • Exposure to loud noises – Prolonged or repeated exposure to loud sounds can damage the eardrum and middle ear structures.


Diagnosing conductive hearing loss typically involves a thorough examination by a healthcare professional, followed by specific tests to identify the underlying cause.

Diagnostic tests include:

  • Physical examination – The healthcare provider will inspect your ears and ask about their symptoms and medical history.
  • Audiometry – This test evaluates your hearing by measuring their ability to hear sounds at different frequencies and volumes.
  • Tympanometry – This test measures the movement of the eardrum in response to changes in air pressure, helping to identify issues with the middle ear.
  • Otoacoustic emissions (OAE) – This test measures the sounds generated by the inner ear in response to a sound stimulus.


The treatment for conductive hearing loss depends on the underlying cause and severity of the condition.

Treatment options for conductive hearing loss:

  • Medications – Antibiotics, antifungal medications, or corticosteroids may be prescribed to treat infections or inflammation in the ear.
  • Earwax removal – Healthcare providers may use specialized tools or irrigation techniques to safely remove excessive earwax buildup.
  • Eardrum repair – Surgical intervention may be necessary to repair a perforated eardrum or remove abnormal growths in the ear.
  • Middle ear surgery – In some cases, surgery may be required to correct abnormalities or damage to the middle ear bones, such as ossicular chain reconstruction or stapedectomy.
  • Hearing aids – For patients with persistent conductive hearing loss, hearing aids may be recommended to amplify sounds and improve hearing ability.


You can take certain steps to reduce your risk of developing conductive hearing loss.

Prevention tips include:

  • Regular ear checkups – Routine checkups can help identify and address potential issues before they become more serious.
  • Proper ear hygiene –Avoid using cotton swabs or other objects to clean your ear canal, as this can push earwax deeper and cause impaction.
  • Avoid loud noises – Protecting your ears from excessive noise exposure by using earplugs or noise-cancelling headphones can help prevent damage to the eardrum and middle ear structures.
  • Treat allergies and infections promptly – Prompt treatment of allergies and ear infections can help prevent complications that could lead to conductive hearing loss.


If left untreated, conductive hearing loss can lead to worsening complications. Persistent hearing loss can negatively impact communication, social interactions, and overall quality of life. Additionally, untreated ear infections or abnormal growths can spread to nearby structures or even the brain, causing more severe health problems. In some cases, prolonged hearing loss can also result in permanent damage to the auditory system. Therefore, timely diagnosis and treatment of conductive hearing loss are crucial to minimize the risk of complications and promote better hearing outcomes.
