I expect you'll need to try hearing aids to find out what they do for the distortion. I have some distortion in my worse ear if I listen to ear buds, but not when my hearing aids are in.
Did they test both air conduction and bone conduction when they did your audiogram? If your ENT gave you steroids, that might be because they saw some conductive loss (in a conductive loss the bone conduction results are much better than the air conduction results), but I'm just guessing.
They really should have given you some numbers for your Speech Recognition Threshold (SRT) and Word Recognition Score (WRS). That would help determine if you need a hearing aid in your good ear. When people speak, a lot of the consonants are in the 2000 - 40000 Hz range where you have a mild to moderate loss. Since consonants are said softly (you can't shout an sssssss sound), that degree of loss could affect your ability to understand people, and the WRS score would let you put a number on that.
I think all brands make hearing aids for a large range of hearing loss. It's the model that's important, I think. Your loss is not too severe to be aided. They might want you to wear two aids so the aids will help you regain the ability to hear what direction sounds are coming from.

Had stapedotomy on left ear in May, 2015. Prior to that had a severe/profound loss across all frequencies in my left ear.
