Occasional loud yelling is not likely to cause deafness in infants, but there is a degree of damage to the hearing and eardrums of infants from loud yelling. Loud yelling is the same as an explosion injury, as long as the sound is strong enough, it can cause damage to the eardrum or inner ear, resulting in hearing loss in infants. Under normal circumstances, because the hearing of infants is not fully developed, the maximum decibel level they can withstand is generally 60-70 decibels, and the sound of people yelling generally does not exceed this range, so once in a while it will not affect the normal hearing of infants. However, if the roar exceeds this decibel, it may cause a certain degree of impact on the baby’s hearing. In addition, if the frequent loud yelling stimulates the baby’s eardrum for a long time, it may lead to serious hearing damage and even cause deafness in infants. Therefore, in daily life, it is important to pay attention to protect the infant’s hearing, avoid frequent loud yelling, and also try not to take the infant to noisy places. If parents are still unsure, they can take their infant to the hospital for a hearing examination and if hearing damage is found, prompt treatment should be given to avoid delaying the condition.
