Occasionally I still have dreams about being woken as a child by the sound of my Dad’s dot matrix printer churning out newsletters. Lost soundscapes, like playing a computer cassette out loud or hearing a modem dial up have a really nostalgic power for me. I wonder, what sound is current now that will disappear in the future? Car engines for one I’d bet.
