Default Sealed units - maximising sound insulation properties

Dear Group,


I am in a situation where I need to minimise sound transmission into a
room (noises such as sirens and raised voices, not low frequency or
road noise).

There is no option of secondary glazing due to the fact that there is
a Juliet balcony. The only option is 'upgrading' the existing 24mm
(4-16-4) sealed units. I appreciate this is not the ideal option.

So, what is the ultimate 24mm sealed unit for sound reduction?

Different thicknesses of laminated glass? Gas filled? Sound insulating
spacer bars?

I believe it's best to have several inches of space between the panes,
also to have them not quite parallel to one another, to avoid standing
waves in the space.
