Hi,
I desperately need an opinion from someone with a good understanding
of materials or noise reduction in general.
I live close to a church and the church bell makes extreme loud noise.
The noise is really loud, going through my windows. I want to put an
extra layer of window - obviously it should be transparent. Should
this extra layer be real "window glass" or polymeric/plastic "PMMA"?
Check what the STC rating for the storm windows is. Here is a good
primer on noise reduction for reducing airport noise, which will
likely be overkill for church bells:

Which transparent material reduces "church bell" sound waves the most?
It relates to the STC rating, which measure sound transmission of
windows and doors in general. Glass can be fine if it is thick enough.
The higher the STC rating is, less sound is passed.
I forgot to add: use a dissimilar thickness of glass (or other
material, but I'd personally probably just stay with glass) from your
prime glass for the storm windows to help reduce resonance.
