Sounds that have disappeared
The whirring of old computers, the sound of TV white noise (before 24-hour TV), rotary dial telephones, old video game sounds, cash registers, dial-up modems, are all sounds that have virtually disappeared - yet only a few years ago they provided us with the sonic backdrop to our lives.
As technology evolves and we lose certain buzzes, beeps and whirrs, other noises are born which take their place.
We’re highly unlikely to hear the staccato click of a typewriter these days, for instance. That sound has been replaced by the more gentle tap of fingers on a laptop keyboard.
How long will it be before the sound of keys, petrol and diesel engines, books and numerous other everyday noises are also gone forever?
Nature’s sounds
As we lose forests and other natural habitats, many species in the animal, bird, and insect kingdoms are becoming extinct, along with the unique sounds they emit.
Sadly, many of these are irreplaceable, but the good news is that there are several institutions dedicated to recording as many of them as possible before they become extinct.
