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"?
Which transparent material reduces "church bell" sound waves the most?
I was told these guys make something that can reduce noise:
http://www.altuglas.com
Which frequencies do I need to reduce (freq. of sound from church
bell)?
How about optimal layer thickness of the transparent material?
Hope somebody is clever enough to help me find the best solution...
