Tympanectomy, a procedure that detaches the muscles from the middle ear, can provide relief for some people. Dysfunctions in the eustachian tube from swelling or an inability to open and close properly can cause:.
Sometimes, people develop eustachian tube dysfunction following an upper respiratory tract infection or allergies. Tumors and injuries to the ear can also cause eustachian tube dysfunction. Learn more about eustachian tube dysfunction here. Symptoms may resolve after a few days. Swallowing, yawning, chewing, and forced exhalation can all help equalize pressure across the middle ear and resolve the symptoms.
Doctors may suggest one of the following nonsurgical approaches, but to date, limited evidence supports their use:. Some surgical procedures may also relieve symptoms of eustachian tube dysfunction. The most common procedure is the insertion of a pressure-equalizing tube. Patulous eustachian tube is a type of dysfunction wherein the tube stays open most of the time.
Typically, the tube stays closed and only opens to equalize air pressure between the middle ear and the outside environment. Some symptoms of patulous eustachian tube include:. Doctors are unsure of the cause of patulous eustachian tube.
In some cases, weight loss and pregnancy may predispose a person to this condition. When these interventions are not sufficient to reduce symptoms, however, a person may require surgery. After 12 weeks of treatment, participants reported significant reductions in these symptoms. The study only included a small number of participants, however, so further studies are necessary to confirm these findings.
Researchers suggest that having high blood pressure may predispose a person to hearing loss. A lack of sufficient blood flow to the cochlea in the ear caused by blood pressure variability can affect hearing. Lowering the variability in blood pressure may help prevent hearing loss.
When the muscle contracts, it pulls the malleus bone away from the eardrum. This causes the eardrum to tense, limiting its ability to vibrate. This essentially dampens the vibrations that are transmitted through to the inner ear.
The tensor tympani tenses in response to loud noises, thus protecting the cells in your inner ear from damage. It can cover low-frequency sounds, allowing you to more clearly hear high-frequency sounds like speech. The muscle involuntarily contracts in responses the sounds that are self-generated, such as chewing, coughing, speaking and yawning. Keep reading to find out more about what could be causing the rumbling in your ear, and what to do about it.
Hearing a rumbling sound in your ear is often a protective mechanism by your body. Sometimes, noises can be too loud and have the potential to damage your hearing. The ear reduces this risk by contracting muscles inside the inner ear that reduce or muffle the sounds. These muscles work to pull the malleus a bone partially responsible for hearing in the ear away from the eardrum. This creates a dampening effect in the ear, which can create a rumbling sound.
Sometimes, there are underlying medical causes that can create a rumbling sensation in the ear. These include:. Sometimes, the rumbling sound is one you can control. A small subset of people are able to contract the tensor tympani muscles in their ear at will.
Some people may do this without even realizing. The ability to voluntarily contract the tensor tympani muscles may have additional benefits in addition to protecting the ear from loud inner noises. The ability to tense the muscles may also mask low-frequency sounds so a person can hear higher and often harder to hear high-frequency sounds that are higher in pitch.
Sometimes, this sound is ringing in the ears. Other times, this sound may be:. The cochlea is still working normally but simply not receiving enough information via its connection with the middle ear. If the problem is somewhere between the cochlea in the inner ear and the brain, this is called a sensorineural hearing loss. There are very many causes of sensorineural hearing loss but exposure to excessive noise or the effects of ageing are the most common.
The typical signs of sensorineural hearing loss are a general difficulty in hearing clearly and problems understanding speech in difficult listening conditions such as in background noise.
It is also possible to have both conductive and sensorineural hearing loss and this is generally called a mixed hearing loss.

Hearing connects us to people, enabling us to communicate in a way that none of our other senses can achieve.
