World Hearing Day…Some Interesting Facts

Disabling hearing loss refers to hearing loss greater than  40 decibels (dB) in the better hearing ear in adults and a  hearing loss greater than 30 dB in the better hearing ear in children. A person who is not able to hear as well as someone with normal hearing – hearing thresholds of 25   dB or better in both ears – is said to have hearing loss. Hearing loss may be mild, moderate, severe, or profound. It can affect one ear or both ears and leads to difficulty in hearing conversational speech or loud sounds.
