Studies Show That People Can “Hear” Silent Videos    

It Is Called Synesthesia And It Could Be Related To Tinnitus    

Synesthesia is a sensory cross-over that allows people to visualize noises or see smells. It was thought to be uncommon. However, an experiment that included soundless moving images showed that it is fairly common. These moving images were able to obtain an auditory response from the brain, thus “hearing” a silent movie. There are animated GIFs that show this effect. Even though it is not clear how this works, it seems to be related to how the brains are wired. The study also asked the volunteers if they had sensory disorders, such as tinnitus, which had a correlation with those who “listened” to the silent videos. More Information click here.

 

Some Types Of Hearing Loss Can Be Corrected By Surgery

Some Types Of Hearing Loss Can Be Corrected By Surgery    

Cochlear Implants Are Used For Damage To The Inner Ear, While Injury In The Conducting Bones Can Be Treated With Prosthetic Devices    

In some cases, hearing loss can be corrected by surgery. The most common type of hearing loss, called sensorineural hearing loss is caused by sudden or frequent loud noise, old age, and medications, among others. It damages the hair cells that transform the sound vibrations into electrical impulses, and it is permanent. This means that no surgery can correct the damage to the hair cells. Therefore, the surgery bypasses them and connect a cochlear implant directly to the auditory nerve. According to specialists, since this surgery is highly invasive, it must be done when hearing aids are no longer an option. There are also implantable hearing aids for patients with moderate sensorineural hearing loss. Conductive hearing loss can be also treated by surgery. This happens when the sound cannot be conducted to the inner ear due to an obstruction in the outer or middle ear. This can be corrected by inserting tubes that equalize the pressure in the middle ear. There are also cases in which the conductive bones suffer an abnormal hardening and must be replaced by a prosthetic device. Check all the types of hearing loss that can be treated by surgery.

Aging Population Has A Lower Tolerance To Sound

They Find Annoying Noisy Restaurants And Public Places    

Some people note that restaurants and other public places are turning up the volume of the music. However, the cause may be a greater sensitivity to noise, as a result of age. One of the consequences of the aging process is a lower tolerance to sound. This is caused by a condition called presbycusis, which distorts certain sounds due to hearing deterioration. This lowers the perception of high frequencies and increases low frequencies. Additional information click here.

 

Drinking At Clubs And Concerts May Increase The Risk Of Hearing Loss

Drinking At Clubs And Concerts May Increase The Risk Of Hearing Loss    

People Tend To Exhibit A Dangerous Behavior Getting Close To Loudspeakers    

Continued exposure to high-volume sounds results in hearing loss. This happens at music concerts and clubs. However, a study showed that when drinking excessively, people tended to move closer to the loudspeakers, increasing the risk of hearing loss and tinnitus. This is known as a post-concert hearing loss. The study also reported that transient hearing loss was lower among people using earplugs, compared to those who did not use them.

Otitis Media Can Have Serious Health Implications

Otitis Media Can Have Serious Health Implications    

It Is The Infection Of The Middle Ear And Can Cause Brain Abscess And Meningitis, Resulting In Headaches And Hearing Loss    

Middle ear infection, also called otitis media, is treated with antibiotics. However, there are other serious health implications, such as hearing loss, meningitis, facial paralysis, and brain abscess. Otitis media is caused by an accumulation of pus and mucus behind the eardrum, as a result of a cold, allergy or an upper respiratory infection. It is common in children up to four years. If poorly treated, it can lead to a brain abscess, which the infection can lead to the accumulation of pus in the brain, which also caused headaches, nausea, and neurologic problems. Another serious outcome is bacterial meningitis, which also causes a severe headache, and the infection of the mastoid bone located behind the ear, which is called acute mastoiditis. A rare, but possible outcome is a hearing loss since the infection is affecting the inner ear. More details click here.

 

Certain Sounds Cause An Extremely Negative Reaction To People

Certain Sounds Cause An Extremely Negative Reaction To People    

It Can Produce Anger, Anxiety, And Even Hypertension And Higher Heart Rate    

There is a condition in which people react negatively to certain sounds. It is called misophonia, in which people overreact to determinate sounds, such as slurping drinks, tapping the fingers, or keyboard clicks, among others. Their reaction is disproportionate, and people are aware that they cannot control it. According to specialists, this aversion develops in childhood and gets worse over time. The reaction includes emotional responses, such as anger and anxiety, and also physiological responses, like hypertension and higher heart rate. It can also be caused by other conditions, such as tinnitus, OCD, or eating disorders. Consequences on sufferers include avoiding social situations and broken relationships.

Stressful Situations Secrete A Hormone That Restricts Blood Flow, Affecting Hair Cells In The Inner Ear    

Stress works as a defense mechanism for us. The body produces a hormone called cortisol, which, in imminent danger, puts the body in a fight-or-flight state, narrowing the blood vessels to divert the blood to the muscles. The problem occurs with chronic stress, in which the body is frequently producing this hormone. Constant exposure to it also affects the organs. Since cortisol restricts circulation, it also affects hearing, because the hair cells on the inner ear depend on a proper circulation to work correctly, converting vibration into electrical impulses. There are different types of hair cells, each tuned for a different frequency, so if one is damaged, the ability to hear the corresponding will be affected. Stress and hypertension also cause pulsatile tinnitus, in which the person hears a noise that pulsates with the heartbeat. More Information click here.
