Filed in: Health Conditions.

Tinnitus or the ringing in the ear, in itself, is not a disease but an indication of underlying conditions that may need attention.

What is tinnitus?

Tinnitus is a characterized condition by the perception of an annoying sound inside the human ear without the external presence of any real sound. [1] It means "buzzing" in Latin, tinnitus is rather a noisy sensation in the ear, something like buzzing, buzzing, whistling or whistling. The sound sensation of tinnitus can be periodic or persistent at all times. The buzzing in the sensation of hearing may be low tone or high tone and may be felt in one or both ears. Tinnitus may be associated with the ear, but its real source lies in the network of brain cells.

Tinnitus is usually categorized in [2] Two types as mentioned below:

Target Tinnitus: Usually, the person suffering from tinnitus can only feel such sounds, however, in some rare cases, it can also be heard by people nearby. This type of tinnitus is described as an objective tinnitus that can be detected by an observer, either near the patient's ear or with the help of a stethoscope pressed around the neck and head area. This type of tinnitus is usually related to a muscular or vascular disease and represents no more than 5 percent of the total cases of tinnitus. It is commonly described as pulsatile tinnitus in which the associated noise can be felt beating in synchrony with the person's pulse. Subjective tinnitus: subjective tinnitus is a more common type of tinnitus and in this case, the patient can only feel the associated sound. This type of tinnitus occurs most often in the general disorders of the ear that occur as a result of the damaged nerve or capillary cell.


Afflictions such as a common cold or being in and around loud areas for a long time, such as a musical concert, can cause temporary tinnitus that is not a serious concern. Other major causes [3] of tinnitus have been discussed below:

Damage to the inner ear: damage inside the inner ear is the most common reason behind the onset of the tinnitus condition. In general, the sounds we hear travel from the outer ear through the middle ear and eventually reach the inner ear. The inner ear consists of a cochlea, a coiled tube that consists of numerous sensitive hair cells and auditory nerves that transmit sounds to the brain. When the cochlea is partially damaged, some parts of the brain stop receiving information. These parts of the brain vigorously seek signals from the functional part of the cochlea, which produces an imbalance in the neural circuits and causes the noise associated with tinnitus. Older age: in the elderly, tinnitus is usually the primary indication Of natural hearing loss related to age. [4] It usually leads to a weakened sensibility of your auditory nerves. Induced by noise: people who work in an environment prone to noise for a prolonged period, such as road personnel, people at musical concerts, noisy factories and industries can also develop the condition of tinnitus. Persistent exposures to loud noises damage the delicate sensory hair cells present in the inner ear and interfere with the process of sending sound signals to the brain. People in defense forces, such as soldiers who are near noisy explosions, are also at a higher risk of developing such hearing loss due to the damage caused to the sound processing of brain tissues. These conditions are known as noise-induced hearing loss. Pulsatile tinnitus: In this type of tinnitus the rhythmic sounds beat together with the pulse of the patient. The causes of pulsatile tinnitus include amplified turbulence or altered blood flow in the neck or head area. This could be due to the accumulation of fat deposits within the arterial walls that result in narrowed arteries that obstruct the smooth flow of blood and cause tinnitus. Brain tumors or deformity in the constitution of the brain may also be the reason behind the appearance of tinnitus sounds. Side effects of medications: the problem of tinnitus can also arise as a side effect of some medications, including: antidepressants, Cancer medications, sedatives, antiinflammatory drugs like ibuprofen and aspirin.

The symptoms

Tinnitus itself is a kind of symptom Signaling some disturbance in the auditory system. [1] It can have varied effects on different people with symptoms ranging from mild to severe.

Sensitivity to sound: Some people may feel more sensitive to music, radio or television and find it disturbingly loud, even if it is in normal volumes. This situation is known as hyperacusis. People suffering from prolonged tinnitus and hearing loss may experience musical hallucinations. Worse at night or in silence: The condition usually gets worse during periods of silence, such as during the night or when you are trying to sleep. During that period, the sound becomes more noticeable, as there is little or no external noise that deviates from the internal ringing sound of tinnitus. Certain physical positions: Some people may also hear a noise when they are placed in specific postures, such as turning their heads or going to bed. Low frequency sounds: People who are in continuous exposure to low frequency sounds, such as traffic noise coming from machinery or underground pipes, common appliances such as grinders, fans, air. conditioning The units often mistakenly assume that the sound of the tinnitus comes from the outside instead of taking place internally from their ears or head.
