Translator: Maram Turkya Auditor: Fatima Zahra El Hafa You arrive home after a long and hard day's work and enjoy a quiet evening alone. But instead of listening to stillness, there is a constant humming sound in your ear … Although there is no source of sound. What you're experiencing is called tinnitus. Perception of noise such as ringing, hissing, hissing, or clicking Without having any external audio source. Hum has been known to disturb humanity since the time of the ancient Babylonians. It struck everyone from Leonardo Da Vinci to Charles Darwin. Today, one in seven people in the whole world experiences This auditory sensation. So what is the source of this constant sound? Normally, when you hear a sound, the sound waves stimulate different parts of your ear. This creates vibrations that move the fluid inside the cochlea. If the vibrations are large enough, It triggers a chemical response that causes them to transform Into vital electrical signals. These nerve impulses then cross the auditory nerve pathway to the brain.
It gives us the result in the form of the sounds we perceive. However, in most cases of tinnitus, The nerve signals that cause these fuzzy sounds Never pass through your ear. Conversely, these sounds are generated internally, by your central nervous system. Under normal conditions, these signals are self-generated It is an essential part of the hearing process. All mammals show continuous nerve activity Through the paths they heard. When there are no sounds, This nerve activity is at the primary threshold that generates the neural code For what is called silence. This activity changes when a sound is made. This allows the brain to differentiate between stillness and sound. But the health of your auditory system can affect these background signals. Loud sounds, illnesses, toxins, and even normal aging It can destroy the cells of your cochlea. Some of these triggers can heal within hours. But enough cells die, either over time or together.
The auditory system becomes less sensitive. With fewer cochlear cells to transmit information, The incoming sounds generate weaker nerve signals. Many environment sounds can be completely lost. Your brain dedicates more energy to monitoring the auditory pathway to compensate for this. Just like when you set the radio grip, The brain modifies neural activity while also changing its control fist For a clearer indication. The brain allocates this increase in posterior nerve activity to help On processing poor auditory input. But it can adjust the basic sleep threshold … No sound is never absent. This is called self-tinnitus. It includes a large number of cases of tinnitus.
Self-tinnitus is associated as a symptom With almost every ear disease, But it doesn't have to be a bad thing. While it may appear surprising, There are no negative after-effects to self-tinnitus. But for some, tinnitus can stir up painful memories Or stir up frustrating feelings, This increases the frequency of intrusive sounds. This psychological episode leads to what is known as "nuisance tinnitus". A condition that can worsen symptoms of both PTSD and insomnia. Anxiety and depression. There is no known treatment for autoimmune tinnitus.
The important thing that doctors can do Is to help patients understand this auditory event, And the development of modified aids with these annoying sounds heard most of the time. For example, sound therapy uses sounds like rain and birds chirping Or music to mask tinnitus and reduce stress. One form of it, called information masking, uses complex and calming auditory cues To deceive the brain away from beeping sounds. And another is called energy masking, Using sounds with the same frequency as the patient's tinnitus To twist the nerve that transmits tinnitus signals. Coaching is practiced alongside counseling, These interventions allow patients to be re-evaluated Their relationship with tinnitus. The least that can be said about the loss of stillness is that it is uncomfortable. Tinnitus reveals that your brain is in constant work of analyzing the world around you. Despite his failure to filter his inner voices. In other words, a tinnitus test It's like listening to your brain making itself … Although it is a conversation you may not want to hear it.
