You make a few interesting points.
It will be pretty good for sound isolation but you still need to be aware of what you are starting with and temper expectations. I think on a quiet night with no rain and wind it will be very quiet and easily do what I want. I now have the second chamber lined and a support floor about the cushions so might attempt a WBTB in there very soon.
Time for SD to work, have no idea but will know soon enough.
I am very interested in engaging one sense at a time to see what effect it has. SD is fine but with no sensory impute a good use could be to use bi aural beats, some form of lighting ( I want to install a Phillips light that is I Phone controlled and produces 15 mil colors, and to use essential oils at times as well. It might be very interesting to flood one sense only and see what effect that has. I suspect there will be real effects in daily life from this and it could be like retraining a dumbed down sense, dont know...
Unlimited funds are one way and creative fun is another so I am aiming for the middle. Not scared to spend a little but like to think my way through and appreciate all thoughts. They get tucked away in the big library in my head for when they are needed.
I think the SD is not the correct way to look at it as its more likely to be stopping external data for the senses to use so hearing is most likely to come to the front as the body is a noisy little beast and this will take over but should allow for an internal focus and away we go to wonderland as we try to make sense of this, LOL or as we observe this and allow out SC to attempt to make sense of this.
Dont know and happy at this stage that I dont
