Dear dude-guy:
Are you completely sure mass is the only thing
to consider?
Only thing, no. *The material's ability to dampen vibration (good
for polymer, poor for glass), and mechanical isolation. *Triple
Yes, this is also what I thought...
Polymer = good at damping vibrations...
Glass = has higher density...
What should I choose? What is the optimal / the best, when there's
already 1 layer of glass (actually 2 thin layers, it's a thermo-
isolating window for cold winters)...
paned glass is like a wall, for both sound and heat transfer
(well...)
Does it matter whether it's high or low frequent
noise?
The spacing between panes will decide whether it dampens /
isolates or resonates / amplifies the noise.
How to find the best spacing for absorbing noise from church bells?
What would you recommend?
