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


Due to my father-in-laws reduced mobility, my in-laws are letting go of their house and have bought a condo in a seniors oriented building. My father-in-law is a big home theater buff, and does like music, so the goal is to turn one of the bedrooms, approximately 16*12*8 into a home theater, complete with reasonable sound-proofing treatment. I am reasonably versed in acoustics, and so far, the several contractors I have talked to have not inspired confidence on being up on the latest "tech".


I would be very interested in any suggestions people would have for modern sound-proofing products they have come across. I am sure I can find a contractor I can trust to do good work, I just think they may need a push to achieve the best results possible.  The contractor can handle the usual issues with sound-proofing.


While money is always an object, the are fairly comfortable and can't enjoy all the usual toys any more, so an appropriate amount can be spent, and they are both in excellent health so will enjoy it for many years and hopefully it will become a hub activity with their friends.

Buildings like that are notoriously noisy (thin walls,lack of insulation,etc.).
I highly doubt you can quiten it down for use as a home theater unless they listen at fairly low volume. Not to mention bitchy neighbors!!!
Acoustic panels such as provided by GIK will not provide soundproofing; they are designed to improve presentation of sound within a room. To keep sound from leaking out is a separate topic and a more difficult task. Usually, significant sound reduction has to be built into a room by using specialized materials (resilient and with plenty of mass).

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

then make it so the room has no leaks, at all. Not a drip. (which is a small part of the fix-it recipe, but we use it here for being a decent illustration of the problem. In the ordinary cases, the room is exceptionally leaky, and acting almost sealed --both at the same time)

Then imagine that the top of this box shaped cistern...has a steel plate on the top of it...and then you start hitting the plate with a 10 lb rubber sledge.

Hitting the plate with the rubber sledge, is likened to the bass in the room.

You have to isolate the neighbors, from that. Even though their very leaky cisterns share walls with your cistern, on all six sides.

Not only that, but make the bass sound good -inside of that cistern.

This is what you are up against, as problems go.

One half of the process is the making of a floating and isolated sealed cistern inside the leaky box.

The other half is fixing the bass in the now isolated box. Usually the entire room has to be rebuilt, in a near to actual tear-down and rebuild, done the right way. The floor, the works.
teo_audio is correct.  Unless the leaks are fixed and the structure is isolated, no amount of acoustic treatment will work.  I have helped build a recording studio using double wall construction, floating ceiling and concrete floors as a starting point and using acoustic calk to fill all air gaps.  It's effective when done properly.   
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.
