It's not about "loud", Eric, it's about "peace and quiet".

On a still morning at New Castle, anyone with decent hearing will hear it at a 1/2 mile and it will not enhance the experience. At someplace like Hobbs or Ephrata, maybe one doesn't care as much.

If you think there is such a thing as a quiet generator you are either indulging in wishful thinking at the expense of your neighbors or you need your hearing evaluated, or both. Maybe it doesn't matter at some uninhabitable hellhole of a soaring site, but it would sure kill the ambiance at most of the (beautiful, quiet, wonderfully suitable for tent camping) sites I frequent.

Have you listened to a Honda EU2200i? It's rated at 57dba at full output, which is variously
described as normal conversation or a refrigerator running. If you are sleeping right next to
the glider being charged, it might seem loud (haven't tried it), but a 100' away, probably not.
But, I don't support running them at night, but between 7 am and 10 pm, or similar, so there is
a quiet time at night. Based on my flying, where I typically use the ASH26E engine for just the
launch, a similar electric glider would only need an hour of charging, so easily done in the
morning while preparing for the day's flight.
