Hi, Vivian:
Dr. Steven Chang (Stanford doc) recommends not getting a hearing aid until hearing has stabilized. That is, when your hearing hasn't gotten any worse over the previous 12 months, then it's time to get a hearing aid. Getting one before then, you'll be chasing a moving target (changing hearing response).
There are a lot of opinions about which conventional hearing aids are best, and it can be confusing. Much depends on the fit and your hearing response (which frequencies are affected and by how much). After researching hearing aids online for a few hours, I came to the conclusion that the best tack is to find a highly qualified "dispensing" audiologist (i.e., one who doesn't simply test patients but fits them with hearing aids). They are up on the latest technologies and will work with you to pair you with the best aid to meet your goals.
Best wishes,
