The volume adjustment for many radio and tele- phone products is through the depression oftwo but- tons, one to increase volume and one to decrease volume.. Two kinds of user feedback are normally associated with this volume adjustment: visually, through a set of ascending and descending bars, presented on the display with more and increasing height bars indicating higher volume levels and less and decreasing height bars indicating lower volume levels; the other user feedback comes from a radio generated tone that is delivered from the speaker at a level that is similar to the current loudness set- ting, with increasingly louder tones indicating higher volume settings and decreasing loudness tones indi- cating reduced loudness settings. On some radios- type products, which have potentiometers to control loudness, loudness feedback is derived Tom the angu- lar position ofthe potentiometer, where turning in a clockwise direction increases loudness and turning in a counterclockwise direction decreases loudness.
