If you think an alarm buzzer is too loud, just track it down and wrap some insulation around it.

I drove a Cadillac once and thought the turn signal clicking was way too loud and annoying, the salesman said they did that on purpose because most of their customers were older and hard of hearing, this way they would remember that they had turned them on.

Needless to say I did not buy one. And they were trying to attract a younger clientel then even. Amazing.
