Making an area sound reverb

How would I go on making a certain area experience a different sound reverb.
I’m trying to have sounds reverb when going underneath a bridge, tunnel, alley, etc.
I have little to know scripting experience so all and any advice would be helpful.

u could make a script that loops through all the parts in a part with no collision, like the part under ur bridge/in ur tunnel and see if it is a player via for loop then add a reverb or echo effect to it using instance.new
