Question
My mother says she can’t hear when people speak softly, and sometimes when my father calls her from behind, she can hear him but doesn’t know where he is calling from.
Answer
Based on your description, it may be a case of age-related hearing loss. Generally, as people age, their hearing tends to decline gradually. It is advisable to have a further examination at a regular hospital. If organic diseases are ruled out as the cause of hearing loss, it is usually due to aging. If the hearing loss is severe, consider using a hearing aid.
