Shalon ,
I am thinking how I can solve your issue with a new device .... What about a sandwich glass window ?
What kind of material you are willing to use ?
You know that do not only glass window who transmit noise, you have to see your structure too.
In market we already have some devices with this objective but, if you want some new, we can research for you.
Please feel free to contact me if you think to hire me, thank you.
