Muffled Hearing

Muffled hearing is a feeling like you have cotton in your ears. It reduces the ability of the patient to properly discern sounds frequencies. Muffled hearing and ringing can be sudden or gradual. It can affect only one ear or both ears. If you are wondering what causes muffled hearing in one ear, they will be discussed below.

  1. Plugged ear – A sudden muffled hearing in one ear could mean that your ear is plugged with earwax or other debris. As the wax begins to build up, the intensity of muffle gets severe. It is not only one ear that is affected, but could also be both ears. (1)
  2. Asymmetric hearing loss - In this condition, the hearing is worse in one ear than the other. The ear that has poor hearing quality has a muffled sound.
  3. Ear infection - It is one of the causes of muffled hearing in one ear. If you have outer or middle ear infection, there could be a build-up of fungi or bacteria in the ear. It could significantly affect the quality of hearing. The sound is muffled in the affected ear.
  4. Eustachian tube dysfunction – The middle ear space is connected to the nose and throat by a small tube. To equalize the pressure in the two air-filled spaces, the tube opens and closes. It is the reason you have a popping feeling when the airplane is going up or when you are scuba diving. If you have sinusitis, the Eustachian tube has difficulty to open and close. This creates a feeling of clogging in your ears, which results to a muffled sound. Muffled hearing in ear due to sinusitis improves once the Eustachian tube clears. If it does not improve, then it could be an indicator of Eustachian tube dysfunction, but the condition will be thoroughly assessed by EENT physician. (4)
  5. High frequency hearing loss - People with high frequency hearing loss has a difficulty hearing high pitched sounds. These people can actually hear the sound but they have a hard time understanding what the sound is. To confirm the diagnosis of high frequency hearing loss, you need to see an audiologist.
  6. Eardrum perforation – Muffled hearing can be an indicator that something is not going right in your eardrum.
  7. Abnormal growth in the ear – Muffled hearing can be associated with abnormal growth in the ear such as a tissue build-up or a tumor. (5)

What does aural fullness mean?

Aural fullness is a feeling of pressure in the ear. It feels like your ear is congested or stuffed, especially if you swallowing or yawning. Aural fullness has something to do with the structure of the ear or a problem in the internal auditory canal. You will also feel a pressure in your ear if there are debris, cerumen, or hair in the ear canal.

It could also suggest an ongoing infection in the ear. To detect the problem, a microscopic visualization of the ear should be done. Usually, the problem is resolved by simply cleaning the ear using a special instrument or through aspiration. Aural fullness is also possible in patients suffering from sudden sensorineural hearing loss. (2, 3)

 

What is sudden sensorineural hearing loss?

Sudden sensorineural hearing loss (SSHL) is an abrupt loss of hearing. It is also called sudden deafness. The hearing becomes more muffled. You could hardly hear the sound because it is so faint.
 This type of hearing loss only affects one ear. (6)

 

What causes SSHL?

A sudden deafness occurs when there is damage in the structures of the inner ear including the nerve pathways between the ear and the brain. The exact cause of sudden sensorineural hearing loss cannot be pinpointed because there are over a hundred causes of SSHL.

Some of them include trauma to the head, injury to the head, inner ear malformation, exposure to loud noise for a long period of time, abnormal growth of tissues, side effects of aging, Meniere’s disease, multiple sclerosis, side effects of medication (ototoxic medication), and congenital SSHL.

Babies with SSHL acquire the disease because of the infection of the mother during pregnancy such as herpes, rubella, and syphilis. A low birth weight can also cause sudden deafness. (7)
