We all grew up with sounds in our every day life that we'll probably never ever hear again because they were generated by technology that's been replaced. Maybe you'll miss some -- maybe you do a little happy dance every time you realize it's gone. Here are nine we thought of... can you think of more?

  • Factory whistles announcing the beginning and end of work shifts
  • Mechanical cash registers
  • Steam locomotives
  • Car backfiring
  • Dial-up modem
  • TV static
  • Telephone busy signal
  • Pagers
  • Fax machines
