Ceiling Soundproofing

[lnewey6]

hi all am after a few pointers for my ceiling the room in question is 10ft by 11ft i plan to screw a batton 2inch by 1inch all round the room then get some mini joist hangers and screw them to the battens then now i can fit my either 3 inch by 2 inch or 4 inch by 2 inch to the hangers then insulate then the 2 layers of soundblock the question is will it work or will it be too heavy

I think it may work but sounds very longwinded! Why not just fix 2x2 to the existing ceiling round the perimter like you say and then at 600mm gaps across the ceiling, then use some 50mm rockwoll between the battens and board it!

All in my opinion of course and if you do choose to do it that way then make sure you get a secure ficking for the 2x2's as the weight of the soundbloc will obviously be hanging on these

The way the OP has suggested will provide a better barrier to the transmission of noise to the upper level. The air gap, if properly sealed is more efficient than thickening an existing surface.

The weight of the ceiling will be determined by which hangers you use. AFIAK the less contact between the 2 layers the better - moreso if the fixing has to penetrate the original surface.

Mattym over in the Acoustics and Calibration forum is a good source of info on most things to do with room acoustics and there are some very readable explanations at www.audioholics.com

Depending on your budget you could use some resilliant bar to compeletly isolate the ceiling!

The problem is though that although this will stop direct noise transference you'll still experience noise escaping by vibrating the walls/floor and carrying through the house!
