Beeps: A lorry, till and car alarm
Whether warning, informing or just simply annoying, beeps are part of the soundtrack of modern life.
They can be loud, such as those on a reversing lorry, or quiet, as on a mobile telephone.
And while some are very useful to one person, for example the car alarm which brings lower insurance premium, they can be irritating to others, such as the neighbours woken by that same alarm at night.
Here is a reversing lorry, a supermarket checkout and a smoke alarm.
