Gain

I’m looking at a specification sheet for a hearing aid I"m Trialing. It’s a Micro Tech Avail 312 RIC.

Are the gain figures the result of what I call volume. The loudness it can put out at a specific ???watt, ? I’m not expecting anyone to explain all this. Just looking for an overall opinion of the two if your familiar with them. Just a couple of bits of info.

The sheet has a column list and at the top is 40/50/60/70 GAIN and under that are :

I’m wanting to know how this Micro Tech 312 wireless RIC Avail complares to the Costco Resound Forza 312 RIC. I know it’s up to the technician and what I think sounds best but
all hardware has limits… possibilities. I’m trying to get a handle on how the hardware compares.
