Question

what does it mean to be \hard of hearing\ according to the video?
it means you have some difficulty keeping up with speech and normal conversation and may use assistive devices.
it means you are completely deaf without any assistance.
it means you cant hear at all.
it means you have no difficulty with speech and normal conversation.

Explanation:

Being hard - of - hearing implies having some degree of hearing loss that can make it challenging to follow speech and normal conversations, and often individuals may use assistive devices like hearing aids. Complete deafness (not being able to hear at all) is a more severe condition than being hard - of - hearing, and having no difficulty with speech and conversation is the opposite of being hard - of - hearing.

Answer:

It means you have some difficulty keeping up with speech and normal conversation and may use assistive devices.
