Hearing Loss!
Hearing Loss has to do with a person who is not able to hear as well as someone with normal hearing – hearing thresholds of 20 dB or better in both ears – is said to have hearing loss. Hearing loss may be mild, moderate, severe or profound. Link
Hearing loss can be caused by many factors, and it is not particular to certain persons. Some believe it affects only the aged, but I have seen children affected by hearing loss. So, there are virus and bacteria involved too but in the end there are various types of hearing loss.
Thank God for technology, there is hearing aid. It helps those with hearing difficulty to hear once the device is used. I saw this first in a movie, Hawkeye. Clint used it in the series, years later I saw it physically where I work, it was donated by the government to the less privileged.
Most times this things start small but we do not take note of it, so we need to watch and take good care of ourselves even at the slightest.
Thank you for your time...
