I have a 1000sq ft room on the 2nd floor that has good noise isolation
all around the 4 walls. However the roof of the building does not have
good sound insulation. It only has R-19 foil backed batts.
I like to select a ceiling tile that has good sound proof properties so
that the noise from the overhead aircraft can be cut as much as
possible. The use of the room is just for general office use, and
occansionally voice recording.
Can anyone suggest an exact make and model of ceiling tiles that we can
use? Something that has a high CAC value and a normal NRC level.
The ceiling is about 10' above the floor and we will be using 2' x 4'

I don't think you're going to have much luck controlling aircraft
noise with just ceiling tiles. At the very least, I'd put in
sound isolation channels (much like furring strips), and then
a layer of Homasote 440, covered by something heavier, like
cement-board. (Or maybe swap the homasote/cement board)
That is a tough one. Around here they had to set up some homes to
reduce the noise and it ran several thousands of dollars per home. They
used extra thick, window glass, special sound proofing materials in all
exterior wills and an number of other tricks. That noise is a little
different than most and harder to stop. It will be coming in from more than
Here is a good source for ideas and maybe even supplies.
In general you want to block air exchange. Air caries sound very well.
(Try opening your car's window as a train is going by.)
Next you want weight. Heavy things (drywall, lead sheets etc.) block
You also want to prevent any direct solid connections. Stagger wall
studs or use special isolation devices to keep the sound from traveling
through the wall (remember the two cans on a string (well wire actuarially
worked) you want to break the wire).
Filling in wall cavities with sound absorbing materials (accustical
fiberglass bats) will do a little.
