Many people find sounds like fingernails scratching on a board, the "squeaking" sound of an aluminum pot or pan hitting a tile floor, or simply the "clicking" sound of a ballpoint pen, and just thinking about it makes them feel uncomfortable, even disgusted.

Sensitivity to sound is a common syndrome, although not life-threatening, it causes many obstacles to the patient's life. Therefore, it is necessary to have basic knowledge to detect the disease early or prevent potential risks.
