That reminds of what I told SWMBO many years ago, after she startled me by pounding loudly on the shop door while it was very quiet and I was just standing there thinking.

"If you don't hear the sound of a power tool, please don't pound on the door because it will startle me. If you do hear the sound of a power tool, please don't pound on the door because it will startle me. Being startled when it's quiet is annoying. Being startled when it's noisy is dangerous."
