There is a very popular question where a father says:
My kids (4 and 5) yell a lot when playing games on the computer. I found an effective cure for this. When I hear loud noises, I [remotely] turn off the screen for 15 seconds on Linux. I've told them that the computer doesn't like loud noises. They totally believe this and beg the computer for forgiveness. They became much quieter, but not to the level that I would be happy, and so I need to continue this educational process.
The dad proceeds to automate the process, making the computer do it automatically whenever it detects noise.
I thought this was a really cool idea for teaching the kids to be quiet. However, one user commented:
Instead of using negative reinforcement, what most of the times leads not to the behavior you expect, you should try positive reinforcement, i.e. reward them when silent. See, your approach teaches me the following: I'm loud when I'm emotional -> Being loud is bad -> being emotional is bad -> being vocal about emotions is bad -> it's best to have no emotions or suppress them as good as possible -> good luck with any relationship (because saying "I love you" is so easy) -> congratulations on ruining your child's life.
