I have moderate hearing loss w/bi lat. hearing aides. Which is better: learning sign language w/no hearing aides, or hearing aides w/no sign language?

I have moderate hearing loss w/bi lat. hearing aides. Which is better: learning sign language w/no hearing aides, or hearing aides w/no sign language?

Also, with hearing aids, one can hear sounds from machines (like cars) and from animals (such as barking). ...Read more
