Cement ceiling impact noise
« on: February 11, 2018, 06:23:31 PM »
My upstairs neighbours are driving me crazy since with their kids running and jumping for hours on end and at very early (5-6 AM) hours on weekends!

What would be the best soundproofing solution for my needs? I very rarely hear voices or screaming but when I do it's very faint and tolerable but it's the impact noise from their feet, objects being dropped and furniture being moved that really drives me mad.

The footsteps are very bassy sounding so very low frequency I would say in the hundreds of Hz or so not sure how to measure that though.

My ceinling is made of cement and is 2.8 m heigh. I was told that the best option is to make a drywall false ceiling and stuff the gap with high density (100 kg/m3) rockwool material.

Not sure if this is the best solution for my needs and I want to block all the noise if possible.

How much lower will the new false ceiling have to be? is 40cm lower enough?

So many variables at play here and I would love to hear what the experts have to say.

You must decouple the drywall from the joist system.
insulating the cavity is a must , you can add MLV barrier to help control and contain noise in the cavity followed by using clips and channel (a must do for impact)
Then I normally follow that by double 5/8" drywall with green glue in between.

feel free to reach out direct to discuss particulars and additional tips.
