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.

A few of my favorites? Rotary telephone. Cassette. VCR. Those are things I remember, along with the typewriter. Pretty much everything else on there is foreign to me.

I haven’t checked, but I imagine Internet Archive probably has stuff like this too, but maybe not presented in the same “museum” way.
