I saw this from a movie. Put up some baffling. What is the meaning of this? I know that baffling means something that close to confusing. But here I don’t get the meaning.
If I take an excerpt,
This phrase is from Avengers, age of Ultron:
We get one shot at this.
I know what I need to do.
The dining room.
If I knock out that easy wall, I’d make a nice workspace for Laura, huh?
Put up some baffling.
Yes, this usage is not that easy to find.
‘Baffling’ in this sense corresponds to these senses of
A usually static device that regulates the flow of a fluid or light.
A partition that prevents interference between sound waves in a loudspeaker.
and focuses more on the material / construction of the baffle.
A baffle (count noun) is something intended to regulate (perhaps moderate) flow (of perhaps sound, wind); baffling (not used with numerals) is the construction material involved. Baffling may be easily workable material, but if it is to be ‘put up’, it’s obviously something more substantial here.
[post edit] It will doubtless be some noise-reducing material here.
