It also lets a person hear the loudness of their own speech and so makes conversation easier. This is most important in deaf young children, as it helps them to develop good speech. The outcome depends on the cause of the hearing loss. It may be temporary as with glue ears in children, curable as with otosclerosis or incurable but manageable as with age-related hearing loss. Only very rarely is hearing loss caused by a more serious condition that affects the brain, such as a tumour.
Most people manage very well with a hearing aid and lead perfectly normal lives.
