esteban,

You will need to hire an acoustical contracting company to come and do a site survey of your condo. If you buy a good spl meter you may learn a lot about where the noise is getting in.

Most likely the noise, especially the noise that is caused by the hvac systems ‘beating’ against each other, will be low frequency noise that is very hard to control.

It takes mass and effective isolation to eliminate low frequency noise.

Surface treatments just won’t cut it as the noise is mechanically transmitted from the source through the structure.

You need to find out where it is getting in - doors and windows are common transmission paths that are relatively easy to fix. Everything else is more difficult - but can be done.

Some condos are fabricated using precast concrete - those are usually pretty good. Other use stick and drywall construction and those will be very difficult to fix.

Let me know if you’d like to chat about it sometime.

Tom
