Conserve the Sound, “online museum”, is clever:
Conserve the sound is an online museum for vanishing and endangered sounds. The sound of a dial telephone, a walkman, a analog typewriter, a pay phone, a 56k modem, a nuclear power plant or even a cell phone keypad are partially already gone or are about to disappear from our daily life.
Accompanying the archive people are interviewed and give an insight in to the world of disappearing sounds.
I haven’t checked, but I imagine Internet Archive probably has stuff like this too, but maybe not presented in the same “museum” way.
