The sound of firecrackers in a year. Fireworks will be lit again brilliant and festive atmosphere, to the annual Chinese New Year festivities icing on the cake. But in the firecracker blast at the same time, an “invisible killer”. Explosive deafness can also strike people who are immersed in joy, especially children and adolescents in their growth spurt. Otologists and audiologists remind friends to protect their ears from fireworks during the Chinese New Year. The pressure waves generated by gunfire, bombs, fireworks and other explosive explosions cause the hearing organs to explode. The average sound of firecrackers is around 100dB, and some can even reach 130dB. This causes a pressure difference between the middle ear and the outside world. The pressure wave acts on the inner ear, causing damage to the cochlear spiral apparatus, blood vessels and nerve fibers. Therefore, blast hearing loss is mostly sensorineural or mixed deafness, and the degree of damage is related to the distance of the blast source.
