When did we last sit at our terminals without turning the sound on? I can hear the kids next door playing in their garden, I can hear the chap 2 doors down stacking wood, and I can hear my cat licking its parts. When the SO uses the computer, he always puts the speakers on, so you get a succession of bleeps, bloops, sproings and glugs. Wonder when he last heard the blackbird singing in the privet tree, or the sparrows chattering on the fence...LTS
