This is basically my life - the default for any noise-producer is off. No cable, so TV only when I hook it up to the lap-top. No good radio reception (joys of rural living) so that also means turning on a computer to listen on-line. Car radio is normally off. Really, our normal environments are so noisy, it is a relief to be able to not have to listen.
If anyone has access to a decibel meter, it is really amazing to see the loud noises that we take for granted in our lives. I really notice how noisy it is in town when I go, since my usual life is so quiet.
