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.

pragmasi,
Condo mid/hi-rise, typical concrete ceiling / floor and walls between units. Current interior construction typical framing and open to "modification".
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.
I've got solid-core gasketed doors in my listening room with added sealing on sides and bottom gotten from the Soundproofing Company. The HVAC system in the next room is inaudible.
Regarding suppression -- my system delivered close to 100% to the next door neighbors (this was in a row house constructed with an air gap between the two houses) but was still audible to the corridor adjacent and to the room above -- primarily bass leakage, and certainly not at a "disturbing" level but the other resident knew music was playing and could identify the track if it was one they were familiar with. 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!
@atdavid I just sent you a PM about the ASC isodamp system but I see you can access the file here -- it'll give you or your contractor a good sense of what is involved
