At one point in my “career” I needed a decibel meter (a device that measures ambient sound levels) and I found myself talking to a salesman.
During the conversation, I asked him who used them and-he said that they sold many to schools to monitor the noise levels that the children were exposed to.

Then I asked him what happened if that ever occurred.

And he answered that if that happened, it emitted a loud alarm.

Then I asked, “Wouldn’t that hurt the Childrens’ ears?”

And he said, “I never thought about that.”
