Deafness means complete hearing loss at speech frequencies above 93 decibels, while deafness implies more or less hearing impairment. Deafness is not unique to a particular age. Factors influencing the increased risk of hearing loss relate, for example, to abortion, older age, too frequent exposure to noise. Hearing loss usually occurs gradually. Symptoms that may indicate hearing loss are buzzing or tinnitus, dizziness, balance problems, ear pain, or a feeling of a foreign object. It is important to check the hearing in newborns in order to react in time to possible irregularities. Symptoms of deafness in a child occur in the form of non-response to sounds and lack of interest in musical toys. Children between the ages of 8 and 12 months will not respond to their name in case of hearing loss, and the absence of speech is possible.
