Demographic situation in the CFR is regressive, i.e. its population is decreasing. More than a half (51.8%) of all deaf and hypoacusis patients living in the territory studied were of the productive age, 68.9% were over 40 years of age. Hearing disorders were represented by neurosensory hypoacusis (48.0%), mixed forms (30.7%), conductive hypoacusis and deafness (18.7%).
