The latest one in my current unit has lets loose a rousing, merry tune for about 30 seconds before falling quiet.

Older card machines would make more unpleasant noises (buzzes, beeps) that carried a vaguely disapproving connotation, while newer ones make a cheerier sound. It makes sense that a vendor would want the card machine to make a gratifying noise, since it rewards the customer. It wasn&#8217;t something I ever thought of before the happier noise was more prevalent. After that, it seemed a no-brainer that when completing a credit card transaction, happy noises should be coming from the machine that takes my money. Although I realize it is all my human auditory perception, the older, angrier-sounding machines begin to feel undeserving.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Growing up, the washing machines I knew would indicated that clothes were ready to put into the dryer either by 1) silence, or 2) a long, flat buzzing noise.
