The great German composer and musician, Ludwig van Beethoven, who was losing his hearing from the age of 28, said: "Never break the silence if not to improve it." At 45, Beethoven He was completely deaf and his life became a torment.
Fortunately, today, it is already possible to break that silence to improve the situation in which they live, according to the World Health Organization, 278 million people suffering from moderate to profound deafness in both ears, thanks to implants cochlear . According to figures from the Ministry of Health of Mexico, around four thousand children are born with hearing problems a year that, if not detected in time, will be condemned to suffer some degree of disability throughout their lives, including the stage of older adults.
A cochlear implant is a small, complex electronic device that can help provide some sense of hearing sounds to a person who is profoundly deaf or has severe hearing difficulties. The implant consists of an external part that is located behind the ear, and a second part that is placed by surgery under the skin. The difference in relation to a hearing aid is important.
The hearing aids amplify the sounds so that the injured ears can detect them; while cochlear implants avoid passing through the injured parts of the ear and directly stimulate the auditory nerve. The signals generated by the implant are sent through the auditory nerve to the brain, which recognizes the signals as sound. Hearing by means of a cochlear implant differs from normal hearing and, it must be said, takes a while to learn or relearn. However, it allows many people to recognize warning signs, understand other sounds of the environment and enjoy a conversation personally or over the phone.
