Hearing impairment can affect lives in many ways. Untreated hearing loss can negatively affect the physical and mental health of the hearing impaired. Exertion, muscle tension, headaches, feelings of isolation, fear or sadness are some of these consequences.
Studies have shown that hearing loss is associated with decreased brain quality and reduced productivity. Other studies have shown that hearing loss can lead to social isolation and depression, which can reduce the quality of life of those affected. Another study suggests that hearing loss can change the personality of older adults. Those affected become introverted and unsociable.
