Sound proofing panels and other equipment - What is the best out there right now

pragmasi,
Condo mid/hi-rise, typical concrete ceiling / floor and walls between units. Current interior construction typical framing and open to "modification".

That's the problem, I am talking to contractors who have some expertise in this area, all recommended by local audio stores, but while their knowledge level of the installation of the products they are used to is good, and I believe they will get the basics right, their knowledge of the most up to date products, and their conceptual knowledge, such as what teo_audio is discussing, the box inside a box, comes across as weak.


I may be expecting too much and I likely just need to keep dialing till I find a suitable contractor. I was hoping to identify some of the leading newer products for residential then work back from there to their trusted contractors. I may be better off starting in the industrial space.


Teo_audio has done a good job of describing the difficulty of this task. It is not easy or cheap. I have already set the expectation that there will be practical limits on the sub-woofers to keep the neighbours happy.


Fortunately it is a newer building, and while I have no doubt the neighbours will be sensitive, the walls between units are concrete as is the floor and and ceiling of course. The hall wall I expect is thinner.

Ordinary contractors know next to nothing about this, so I urge you to do significant research and/or consult a professional in the field.

Thank you for the post folkfreak,

I have the width and length to do room in a room, but height is definitely an issue that may make it impractical. We can rebuild interior walls, but the ceiling and floor are fixed. I am going to have to get an accurate dimension. Even 6" in that dimension is huge one way or the other.


At some level the ASC system is room within a room (the floor especially), but the method doesn't matter, just the results. At least on the walls it would seriously impede the dimensions. I am going to contact them Monday and see if they can put some numbers around db suppression.  folkfreak, what is your feeling in terms of suppression?


I may have an idea for the door. I was looking at used/surplus vault doors.

The way you are describing it sounds sufficient for this installation. It does not need to be perfect, just good enough, and more than good enough to still enjoy the experience.

Basically think of it as taking 90+ dB in room down to normal what you would consider acceptable leakage for a person with a TV in the room next to you playing faintly.

I guess this goes some way to saying that in a residential setup with adjacent rooms its very hard to get to 100%, which is why my new build is a garden room 60' away!

This is just a very small part of what goes into soundproofing a room.
