Sound Insulation Help

soundman111

Dear All,

Hope your all doing okay.

I have had the dividing wall insulated in our bedroom as before we could hear alot of noise from the neighbors. The dividing wall lets no sound through now, but some banging sounds seem to be coming from the neighbors property, which i can hear that disrupts me watching TV in the bedroom. The houses are poorly built and i do not feel the neighbors are being unreasonable.

The noise seems to come through the ceiling around the dividing wall, i do not have the finances or space to insulate the ceiling by adding mass, as i have fitted wardrobes and i would have to get rid of these if i lowered the ceiling.

I have spoke with an acoustic company and they stated if i insulate the loft 1 meter from the dividing wall above my bedroom i should have a very good noise reduction. Does anyone know a good type of insulation for the loft that helps with noise transmission please? Further for any holes in the dividing wall in the loft does anyone know any type of sealant i should add to help with noise transmission?

My thoughts were some type of mineral wool insulation in the loft and possibly a barrier mat on top of this insulation or some type of silent board material. I was thinking add some type of acoustic sealant for any holes in the brick work i find in the loft dividing wall also. If anyone can share any advice i would be very grateful, i understand it will not reduce noise 100% but any reduction would be helpful. Many thanks for taking the time to read this post, i would be thankful if you could share any advice.

Many thanks,

Paul

I think there was a thread on this recently, someone spent a lot of money soundproofing their house and it made no real difference. The problem is the way sound waves work - they can transmit so many ways, along joists, through the air, cavities, windows, lofts.

Maybe consider headphones for watching tv, might be cheaper!

A friend once put sound proofing up on a wall using resilient bars stepped out on stud work and the attaching sound resistant boards to them to give a much isolation from vibration as possible, he spend ages researching it all and found out, as you have, that sound just travels around it and you really need to do more than a single room. He gave up and bought a detached house eventually. I think it may be worth seeing if a specialist firm could help out and how much that would cost?
