Depends on the size, thickness and type of glass, how it is mounted/supported, how and where it is broken, and ...

....whether there is echo in closed room, constructive/destructive interference after reflection in exact point where is microphone..

etc. etc.

 

Therefore experiments with sound are performed in "noiseless rooms" (aka "Anechoic chamber")

Buy decibel meter on e.g.

https://www.ebay.com/bhp/decibel-meter

then perform experiment, and tell us, what was results, in CSV table with distances...

They are for $15-$20. .

Most sound level meters (and certainly the $20 ones) are not designed for short duration sounds and may give inaccurate answers in this case.

Yes, but I only need an approximate/inexact value - so I can use it as a reference point against the volume of glass shattering in general

i don't think you can. A breaking cup sounds different to a pane of glass. The pane can briefly act like a drum skin and can push air like one, giving a lower frequency component than say a cup. What you are effectively asking is "How long is a piece of string?"
