Hello guys,

My neighbor downstairs is a fan of loud music (often with huge bass sound) and their music last all day long, and from the low frequency impulsive noise (like boom boom boom) gets through the floor.

The apartment floor is actually hardwood on top of concrete (concrete condo), it stops most of their music sound but just can’t stop the low frequency, I measured about 50 decibels around the range of 60-120Hz in the room when they are not having party, it can be over 60 decibel during their party.

I’d like to use some kind of acoustic underlay (rubber/MLV sheet) on top of my hardwood floor and put another layer of carpet on the top of this underlay. My goal is to have the noise under 40 decibels.

My question is, could this solution help me reducing some of the low frequency noise, please? Or would you have an idea how much would this solution help me, please? An approximate number will be welcome.

I’m using an iphone app for the measurement by the way.

Thank you in advance.

F, A barrier design that will be effective in the 20 dB attenuation range will need to be 3″ – 4″ thick.

As the door opens toward inside, I think even for 10 dB attenuation will be a big project for us. Maybe an easier solution is to call 911 every night.
Anyway, thank you for your answer.
