All about hearing loss

Hearing loss is described according to the degree of impairment. It is usually explained as mild, moderate, moderate to severe, severe or profound.

  1. Mild hearing loss -- The person can hear conversations conducted in normal volume but has difficulty in hearing whispers, soft sounds or low volume sounds.
  2. Moderate hearing loss -- The person cannot follow conversations conducted in normal volume. He can hear if people speak in loud voices. He himself might be speaking in a loud voice.
  3. Moderate to severe hearing loss -- Even when speech is loud, they do not hear all words and sounds clearly.
  4. Profound hearing loss -- Such persons cannot hear any sounds without the help of hearing aid.

Deafness is another name for profound hearing loss. However, people who call themselves 'Deaf' usually are identifying themselves as members of the Deaf Community. This means that they use sign language as their first language. Not all people with a severe or profound hearing loss use sign language.
