You might be able to stop higher frequencies this way but not anything below 250 Hz. It would have to be very heavy light blocking and layered. Your best bet is to have them custom made. If you go to your local fabric store to pick out your fabric they will have a list of seamstresses they recommend. You can get ceiling tracks from a number of sources.
