We live on this planet and passively accept the nuisance of various voices every day. For certain types of sounds, such as scratching a blackboard with a fingernail, everyone who hears it gets goosebumps and feels a tingling in the scalp. However, some people will hate the sounds that everyone is accustomed to, for example, when they hear the sound of others' mouths when they eat, they want to hit people. Is this an emotional whammy, or is it the effect of a disease? Let's parse it now.
The same sound, some people like, some people hate, even can't stand it. Therefore, some scholars call those feelings of disgust for specific sounds phonophobia. Related studies have found that in patients with phonophobia, there are significant changes in the structure of the frontal lobe of the brain, and brain activity also changes. Brain imaging studies have found that people with phosombia have different connection patterns in the frontal lobe, which trigger brain overactivation due to specific sounds, and have a faster heart rate and sweating. In-depth studies have found that in the gray matter of the prefrontal cortex of the brain of patients with phosomy, there is a higher myelin formation.
The phenomenon of phonophobia has also attracted the attention of psychologists. Some scholars believe that disgust due to sound is a special emotion and causes a unique physiological response pattern. In Spanish, there is a specific word, grima, that specifically describes this feeling, expressing disgust, and experiences such as scalp tingling, sudden chills in the spine, shivering, and wanting to escape.
After research, a team at Newcastle University in the United Kingdom believes that the physiological basis of phonophobia is due to unpleasant sounds that trigger a strong fight or flight response. In the study, brain activity was measured by 3 sets of sounds, such as neutral sounds such as rain, busy cafes, and kettles boiling; unpleasant sounds such as babies crying and screaming; and sounds that trigger phonophobia, such as breathing sounds and chewing sounds. Tests have shown that patients with pheophobia have elevated activity in the frontal lobe area and the anterior isola cortex region when a trigger sound is heard; in normal people, only the anterior isola cortex activity rises, while the frontal lobe area activity decreases.
Scientists believe that the sensation of sound in our human ears is mainly related to the frequency of sound waves. The ear canal can play a resonant amplification effect on the sound of special frequency bands. In this way, some sounds become toxic sounds, for example, the ears are most sensitive to sounds in the range of 1000 to 5000 hertz, the sound of fingernails scratching the blackboard is in the frequency band of 1000 to 4000 Hz; the sound of babies crying is also in the crazy frequency band, this sound is similar to an alarm, is the baby's distress signal. In the process of human evolution, the sound of such alarm bands is imprinted into the brain, and when similar sounds are heard, the activity of the amygdala in the brain will increase, and the amygdala is in charge of negative emotions, which will cause fear, anxiety, anger and other emotions.
Phonophobia, named in 2001, is currently neither an auditory disorder nor a mental illness. Phonophobia, also known as selective voice sensitivity syndrome, refers to a strong sense of disgust for a particular sound, and a small number of people will be abnormally sensitive to certain sounds and develop irritability and even induce aggressive behavior. The sounds that trigger phonophobia are varied, some people will get angry when they hear the sound of chewing potato chips, and some people will hit people when they hear the sound of sucking nose or snorting. Therefore, hearing a particular voice burst into anger is not a pretense, but a symptom caused by brain structure or reaction. However, such symptoms are not yet classified as diseases, and there is no special treatment. Avoidance measures such as earplugs can only help calm emotions.
Phromphobia research, which recently won an award. 3 psychiatric researchers won the 2020 Funny Nobel Prize for investigating phonophobia. Three scholars surveyed 42 people with phonophobia and found that 81% of them could not stand others' spitting; 64% hated that others' breathing was too loud; and 59% could not stand the sound of others tapping on the keyboard. The emotions of these patients will rise to the level of wanting to hit people, and patients will feel pain, and even lose their social function and cannot participate in social activities. Scholars believe that the essence of phonophobia is a kind of obsessive-compulsive disorder, and the more unwanted things are, the more they will occupy the mind. Because of the excessive concern for a particular sound, there is a strong desire to ignore the existence of such a sound, and the result is that the sound occupies the attention in a more intense way, thus causing an emotional reaction. It seems that the mechanism of phonophobia needs to be further explored, and I hope that scientists can one day win the real Nobel Prize.
