Loud social settings seem to be a difficult challenge for everyone, and I don’t think that any hearing aid manufacturer has found the silver bullet for it. Hearing aids can make it better, but you will never have perfect hearing again.
I would imagine that your speech recognition scores must be not-great with your low frequency loss, even though it wouldn’t be classified as severe.
My only real advice would be to try to not focus on “discrete”. I have worn hearing aids for over 25 years, had 3 different styles, and as a professional trainer I interact closely with people every day (and a different group of those people every week!). I always make sure that I tell people that I am hearing impaired, and even after working around me for a couple of days, their reaction is almost universally “really???”.
I currently wear a style called “RITE”, which stands for “Receiver in the Ear”. These are very popular with basically everyone these days because they are modular and very easy to fit.
The “speaker” - the part that delivers the amplified sound - is a tiny device that goes entirely into your ear canal, putting the speaker very close to your eardrum. In most cases it is held there by a little soft silicone mushroom. They usually don’t require custom-made ear molds. The speaker is connected to the electronics by a fine wire that snakes out of your ear and loops up over the top. The battery and all of the working parts hang from that wire behind the ear.
As a hearing impaired person, I actively look for hearing aids on people, and they are still sometimes hard to see.
I guess what I am trying to say is “who cares?”. My friends and family don’t care that I wear hearing aids (and certainly don’t think less of me because of them), and the strangers that I don’t know? Well, I don’t care what they think anyway!
