What Causes a Crackling Sound In the Ear?

Tinnitus is a condition that causes a person to hear sounds and noises that no one else can hear. Tinnitus is a fairly common condition that occurs in about 10% of the population. Tinnitus usually occurs in the elderly, but recent studies have shown an increase in the occurrence of tinnitus in the younger population. It is more than likely that this change in appearance is due to the increased exposure of younger generations to loud sounds such as music, guns, hair dryers, etc. People suffering from tinnitus hear various sounds such as musical tones, hissing, whistling, buzzing or ringing. No two people will hear exactly the same noise. Most affected people find these sounds to be just a nuisance or an annoyance, but they can go on with their daily lives. However, in some cases, tinnitus can greatly affect the quality of life due to the constant noise nuisance.

Tinnitus can be classified into two categories, objective and subjective. Only a doctor can distinguish between the two types. Objective tinnitus can actually be perceived as a sound coming out of the ear. Anatomical body sounds such as muscle spasms, heartbeat or pulse, and blood flow can be heard through the patient’s ear. Subjective tinnitus is more common because it describes the symptoms that the patient feels. In subjective tinnitus, the sounds emanating from the ear are not present for the doctor to hear.

There is no cure for tinnitus and it is difficult to determine the exact cause of tinnitus. There are four areas where tinnitus can originate, the outer ear, the middle ear, the inner ear and the brain. Wax or foreign bodies can block outside noise and cause damage to the outer ear. In the middle ear fluid, an infection or disease in the bones of the ear or in the eardrum can cause damage. Damage to the nerves in the inner ear can distort the noise. Finally, abnormalities in the brain can cause tinnitus symptoms.

In addition, several diseases, deficiencies, medications, and emotional factors can also cause tinnitus symptoms. However, the most common cause is damage to the nerves in the inner ear (cochlea). Nerves in the cochlea transmit electrical impulses to the brain, which interprets that these signals sent to the brain are distorted. Distorted signals are interpreted by the brain as noise. Determining how the nerves became damaged is the ultimate cause of tinnitus symptoms.

Older people are more likely to experience tinnitus symptoms. As we age, like many other parts of the body, the inner ear or middle ear gradually changes, causing symptoms of hearing loss. Age-related hearing loss is called presbycusis. The change in the ears occurs over a long period of time and usually occurs in both ears. In younger people, exposure to loud noise can also cause hearing loss. The cumulative effects of repeated exposure to loud noise will eventually lead to presbycusis. Depending on the duration of exposure and the frequency of the sound, it will be determined whether the nerves in the ear are damaged. In some cases, the damage can cause temporary hearing loss, but permanent damage can cause tinnitus or the need for hearing aids. Although, not all tinnitus symptoms are caused by exposure to loud environments or due to age. Some of the changes that can occur inside the ear include otosclerosis. Changes in the ear bone cause stiffening of the bones in the middle ear. This abnormal growth puts pressure on other bones and nerves inside the ear.

Our normal bodily functions such as breathing, heartbeat, muscle contractions and blood flow create noise. However, most people do not hear these sounds because we are surrounded by noise that obscures our ability to hear these tiny sounds. However, if you eliminate external noise, you are more likely to hear the anatomical sounds of your own body. In addition, certain changes in the body can cause you to hear these sounds more easily.

Metabolic disorders in the body can cause tinnitus symptoms due to deficiencies that interfere with metabolism. Most metabolic disorders are genetic in nature, which means that they are passed down through the genetic makeup of the parents. Metabolic disorders can cause abnormal enzyme function, the body produces too much or too little of the necessary substances or cannot break down certain substances. Common metabolic disorders that cause tinnitus are thyroid disease, hyperlipidemia, vitamin B12 deficiency, and iron deficiency anemia.

Anemia is a condition in which the blood becomes thinned with red blood cells, which provide the body with oxygen and nutrients. Diluted blood rushes through the veins so fast that it makes a sound. Anemia can cause fatigue and eventually death if not treated immediately.

Meniere’s disease is a disorder that causes abnormal flow of fluid in the inner ear, affecting hearing and balance. Usually causing hearing loss and tinnitus in one ear, Meniere’s disease causes fluid pressure in the inner ear to increase. Less likely causes of tinnitus include brain aneurysm, brain tumor or acoustic neuroma. Aneurysms usually occur in arteries at the base of the brain. In the blood vessels, there is a bulge that fills with blood and there is a risk of bursting as it increases in size. As the size of the aneurysm grows, the pressure on the surrounding blood vessels increases. Brain tumors and acoustic neuroma, a non-cancerous benign tumor that occurs in the brain, puts pressure on the blood vessels, which cuts off the supply of nutrients and oxygen to the brain. Therefore, the brain interprets elevated blood pressure as distorted sounds. Acoustic neuromas usually occur on the cranial nerve that runs from the brain to the inner ear, affecting balance and hearing.

Earwax, also known as cerumen, is secreted in the ear canal to protect the ear from bacteria, fungi, insects and water. It is necessary to regularly remove the wax from the ears in order not to allow the accumulation of excess wax. Although Q-tips were originally designed to help remove earwax, they are now hardly more dangerous than helpful. Using a Q-tip can cause earwax to go deeper into the ear canal, which can cause it to hit the eardrum. When the wax is pressed against the eardrum, the brain perceives it as sound signals.

Head, neck and temporomandibular joint (TMJ) injuries also affect tinnitus. Chiari malformation, multiple sclerosis, skull fracture, whiplash injury, closed head injury, and TMJ disorders affect the ears, nerves, and blood vessels of the brain. Injuries and disorders cause abnormalities so the brain perceives electrical impulses differently than it would in a normal person’s brain. Neurological disorders also cause disturbances in the functioning of the brain, which can cause tinnitus symptoms.

Prescription and over-the-counter medications also affect the body’s ability to decipher sound waves. Drugs, both legal and illegal, can cause the brain to receive distorted signals, which can cause tinnitus. Aspirin, antibiotics, cancer drugs, diuretics, quinine and chloroquine can cause tinnitus symptoms.

After all, stress plays a big role in the body’s ability to function properly. Unfortunately, stress can hinder the brain’s ability to interpret and perceive stimuli. Atherosclerosis, high blood pressure, depression, anxiety and nervousness are all stressors that take a toll on the body, causing interference with its ability to function. Therefore, the brain can misinterpret the electrical impulses, which causes tinnitus.

Unfortunately, with so many causes of tinnitus, it is difficult to quickly determine which one is causing subjective or objective symptoms. Therefore, it can be a lengthy process to search for the specific cause of your condition. Until then, tinnitus can be a big inconvenience and a nuisance in your life. Additionally, the amount of testing and treatments you try without relief can be frustrating. However, there are many alternative remedies that can be useful in reducing your symptoms until you have completely resolved your current condition.
