When was the last time you heard a dial-up modem? A dot matrix printer? A CD dropping into its plastic tray? Did you know it would be the last time? We talk to Rick Adams, a British reporter, about the impact of Big Ben being silenced for repairs next year and Madeline Ashby, a futurist, who has some pretty wild ideas of what sounds we’re about to lose... and have already lost but haven’t realized it yet.
