The baby is a hearing being since it is in the womb. At approximately fourteen weeks he begins to hear the sounds coming from outside and around 22 weeks the ear has already completed its development, therefore we must take care of baby's ears even from the womb.
A recent study on the effects of noise exposure has concluded that loud noises modify the brain to the point that it influences speech interpretation, causing increasing difficulty in distinguishing speech sounds.
According to the latest study by the School of Behavioral and Brain Sciences at the University of Texas at Dallas published in the Ear and Hearing magazine, the official publication of the American Auditory Society, listening continuously to some sound or noise that is too loud does not only cause deafness Over time, it also affects the area of the brain that processes sounds.
Although the study was conducted in rats, they observed that this area is equal to a brain region of the human being whose function is to process sounds related to speech, so that exposing the baby to loud noises, even from the womb, could have an impact on poor speech development
