Research from IBGE, Brazilian Institute of Geography and Statistics, show that 9.7 million Brazilians suffer from hearing impairment. This figure represents 5.2% of the Brazilian population, of which 2.6 million are deaf and 7.2 million have great difficulty in listening. It is estimated that about 20% of Brazilian children at preschool age suffer from some hearing impairment.
Many people develop hearing problems throughout their lives, due to bad habits, accidents or illnesses.
Listening to loud music in headphones or shows, working in an environment with high noise levels or constant ear infections are things that can contribute to causing hearing loss. Therefore, it is important to be aware of the signs that point out to some hearing problems and then go for specialized medical care.
