Hearing loss is becoming more frequent, especially in developing and highly developed countries. Progressive hearing loss is commonly a result of noise. Sources are often found in industry, but they also occur as environmental noise associated with the use of various types of transport. In children and adolescents, the biggest threat is recreational noise, i.e. music on headphones, concerts, discos, and toys. Noise not only affects the hearing of children, weakening it and increasing susceptibility to hearing loss in later years, but it also has so-called extracoustic effects. These include disturbed sleep, concentration, aggressive behavior, stress, and anxiety. Hearing loss arising from noise primarily affects high frequencies, reducing the ability to understand speech. This causes, among others, problems with speech development, education, and communicating with peers, which is why it is important to prevent hearing loss and to diagnose the problem as soon as possible. The aim of this work was to present the most important information on hearing loss caused by noise in the environment of children, and to show the social extent of the problem.
