Very interesting, thanks Hesham: this is a brand new reason to choose a twin-fuselage design, bloking the noise waves of a central engine, thus redicing aircraft noise...

It seems to me that the engines appear to be fairly close to the wingtips. I believe that this would create considerable problems.
