Michael, thank you for your kind answer.
we have different unit measures (inches vs meters) and (pounds vs kg).
my room is in meters 3.7 x 3.2 x 2.5 meters
and when I spoke on bass traps or panels, I've meant meters too 1.2 x 0.6 meters or in centimeters 120 x 60.
because it is a standard size of for example rockwool panels.
as for density I have a very important question but I did not find the answer...
for example, taking rockwool...density
rocksol = 100 kg/m3 with max width 8 centimeters
rockfire = 120 kg/m3 with max width 12 centimeters
from one side more dense is better is... but
is there the threshold after which the waves become reflecting and not absorbing ?
other words, rocksol with 100kg/m3 is good but is rockfire with 120kg/m3 would be better ? (the case is base traps with 40-120Hz only)
== other practical questions ==
: rockwool vs glasswool,
it is possible to have a for example euroacoustic panels with 70kg/m3 of glasswool.
but it is interesting to know, if 70kg/m3 will absorb better than 100 or 120 kg/m3 of rockwool ? (for the same size of cause)
: width of a panel,
the panels are of different widths
what does absorb better ? one panel of 8 centimeters width or 2 panels of 4 + 4 centimeters glued together ? perhaps with 1-2 centimeter of space between them ?
: resonant space,
at which degree the resonant space before the absorbing material is important ?
for example, we can construct a panel :
- just wrapped in a cloth (the parallel question - what type of close is better? )
- just putting in a coffer (the parallel question - what material is better? pine wood?)
- putting in a coffer and provide an around 20-30 centimeters resonant space before rockwool/glasswool absorbers
(here are many parallel questions)
--- what material to better use for membran (between absorbers and air) ? paper, wood, aluminium ?
--- is there the optimal width for a such resonant space ? the same as the absorber width ?
--- how much this space influences the overall absorbtion coeffitient ?
--- is there the difference of using this space for rectangle panels or triangle bass traps ?
--- is, in the case of triangle bass trap, this space necessary / desirable ?
Thank you beforehand for the explanation!
