And we're not talking a pleasant tone here, we're talking the kind of annoying ring that usually signals your burrito is done in the microwave, or you've just entered your local 7/11. Doc believes these little annoyances are what contribute to job stress, and they are certainly distracting.
Of course, there has to be some way to indicate that something is wrong or to serve as a gentle reminder that you forgot your original. But I would think the sounds could be a lot more pleasant and less jarring. But maybe I'm wrong and the printer manufacturers have done all kinds of studies and discovered that only a sharp, alarming beep will do. I hate to think that's the case.
If you are a machine designer and know about these things, then explain to Doc why a simple and pleasant harmonious tone (like when you start up your computer) won't do the job. Do we really have to beep, beep, beep? It's enough to drive an office worker to distraction.
