Hearing loss and tinnitus are common abnormal auditory manifestations. Tinnitus can cause headaches, insomnia, dreams and other troubles, causing anxiety, depression and other bad emotions; hearing loss affects verbal communication, causing communication difficulties, slow response and other problems .
SadWhat is the relationship between hearing loss and annoying tinnitus??The editor will take you to take a look.
Currently recognized,Hearing loss is the most common cause of tinnitus.When hearing loss (insufficient auditory input) occurs, our auditory systems at all levels will begin to compensate for the hearing loss.
Studies have confirmed that the most active auditory compensation occurs at the level of the thalamus. At the same time, tinnitus signals are generated in the thalamus. These signals are transmitted to the auditory center of the brain to produce “tinnitus.”Although the tinnitus signal is a distorted sound signal generated by the spontaneous excitement of the auditory system, it can also partially compensate for the lack of sound input.
Clinical phenomena show that the relationship between tinnitus and hearing loss is intricate.People with the same level of hearing loss may not have the same tinnitus; people with the same level of tinnitus may have different levels of hearing loss.
The type of hearing loss most clearly associated with tinnitus is acuteHearing loss,Such asSudden deafness.
Sudden deafness causes the auditory system to immediately activate the auditory compensation mechanism, so that the auditory system at all levels compensates for the lack of sound signal input, and tinnitus signals are generated during the compensation process, resulting in tinnitus symptoms.
At the beginning of sudden deafness, this not so strong tinnitus signal can not only compensate for part of the hearing loss, but also has a certain warning reminder, prompting the patient to produce a certain degree of anxiety and nervousness, increasing sympathetic nerve activity, thereby improving auditory compensation Efficiency, and at the same time, it will not cause serious distress to patients.
As the hearing condition stabilizes, the body gradually adapts to hearing loss, auditory compensation begins to weaken, and tinnitus is relieved.
Some patients whose hearing cannot be fully recovered after sudden deafness may have a slight degree of tinnitus, which is a “scar” that appears after the auditory system is damaged, and generally does not affect life.
Recurring fluctuating hearing loss, such asMeniere’s disease and otosclerosisTinnitus can be understood as a recurring process of acute hearing loss.
With each repetition, the auditory system activates the acute hearing loss compensation mechanism. In order to compensate for the lack of auditory input caused by the hearing loss, the auditory centers at all levels spontaneously generate tinnitus signals and transmit them to the brain. The tinnitus appears and then slowly clears.
Because of this, fluctuating hearing loss accompanied by tinnitus should start from the cause and treat hearing loss in a targeted manner.
Tinnitus after hearing stabilization takes a long time to recover, Can give a certain sound compensation, the compensated sound can effectively reduce the burden of auditory compensation, so that the symptoms of tinnitus can be gradually relieved.
sectionPatients with presbycusis are often accompanied by symptoms of tinnitus.
Senile tinnitus tends to become chronic, hearing loss gradually worsens with age, and tinnitus signals gradually accumulate, At this time, chronic tinnitus may appear gradually worsening and difficult to eliminate.
For presbycusis, there is currently no clear and effective drug or surgical treatment.In this case, in order to reduce the burden of auditory compensation, the auditory input is compensated,Let ears get more external sound stimulation, which is an effective means to improve tinnitus symptomsAt the same time, we should also actively improve the factors that cause the auditory system to decline, such as staying away from noise, quitting smoking and alcohol, regular work and rest, and paying attention to diet.
Everyone’s auditory system is specific, and different types and degrees of hearing loss have different effects on tinnitus..When hearing loss and tinnitus occur, you must go to the hospital or a regular hearing center for help, and actively respond to reduce the trouble caused by hearing loss and tinnitus.
