And as fate wanted when [the site] was moved to Airport City,
the first word in Airport City is Airport.
And then we send our acoustic consultant
Dr. Michael Bogolovsky to check, and he calls us
and with a hysterical and trembling voice says
that a jumbo landed on top of him during his tests.
Exactly so. And he has no idea how to solve the building now,
as he says that when a Jumbo landed on top of you, you can't do anything.
Truth be told, we were somewhat stuck at this point.
But the solution we ended up with,
which might seem to some a bit forced
but ultimately works with the building, is using the framework
the steel framework which creates the hall's dome
and pour on it a 15cm concrete layer
which creates a complete envelope of concrete
which encompasses the entire hall and insulates its acousticaly.
Just this is not enough,
you need layers of air on the inside and outside
and more insulation layers, but
this reaches the required attenuation levels
Becuase we, or the IAA can say that there's no chance that
a Jumbo will land there, but if this happens just once
and I'm sitting there during a performance,
I don't care what happens during the other 364 days,
this is a chance we can't take.
So we create a type of a closed enveloped
of concrete which creates the required insulation.
We hope.
[Arch. Bruce Levin] "How thick?" 15 centimeters.
Its just a question of density and mass, mass-wise this is the [thickness we needed].
