If you find that your hearing ability is declining, you have to approach Ear-Nose-Throat (ENT) doctors. They can refer you to audiologist for further assessment. According to the assessment, audiologist or speech therapist can help you to select some devices (e.g. hearing aid, cochlear implant) to restore your hearing ability. When the hearing impairment has affected communication, speech therapist can provide some therapy for aural rehabilitation.
However, children sometimes cannot tell about their hearing ability accurately. As a result, parents have to pay attention to children's response to sound and speech. If parents have found any doubts, they have to found some professionals ( e.g. doctors, audiologists, speech therapists, etc. ) to give a help.
