It looks like the densest mineral wool isn t even available in the largest thickness and 6 of the least dense wool cw 4 has better absorption than 4 of the most dense wool cw 8.
Rockwool acoustic panels thickness.
This is the insulation material.
Doubling the thickness results in an almost 400 increase in absorption at 125 hz while doubling the density is only about a 20 50 increase.
The materials i used.
I got 8 meters by 1 50 meters or 26 feet by 5 feet.
Notice that the.
Sound is a form of mechanical energy.
It is produced when particles oscillate around their equilibrium position.
S m2 will absorb perfectly at 500 hz if i use only 90 mm thickness 3 5 with an air gap of 70 mm.
The roxul mineral rockwool family of products is available in various densities to support different applications.
In physical terms sound is the mechanical vibration of a gaseous liquid or solid elastic medium.
Rockwool safe n sound rockwool s popular stone wool fire and acoustic batt insulation is now offered in a new 6 thickness.
Acoustical performance for roxul con rock board 60 6lb per cu ft.
Or i could go thicker for the panels but closer to the wall.
4 1 pieces of wood.
I used 18 pieces of 125cm 49 and 18 pieces of 62cm 24 for nine panels in total.
