MICHEL MARTIN, HOST:
The internet is now a bit more noisy. That's because audio files on social media have rediscovered an amazing fact. The BBC's vast sound effects library is open to the public. Thousands of clips can be downloaded for free, so people have been pulling out all kinds of weird sounds. NPR's Chloe Veltman did, too.

VELTMAN: ...And newer ones, including the sound of morning traffic in Tucson, Ariz., recorded a hundred years later.

VELTMAN: There are around 33,000 clips in total, more than double the number available when the BBC first made the archive public in 2018. And they come from all over. Here's the call of the Tibetan snowcock...

VELTMAN: ...And here's famed naturalist David Attenborough gingerly approaching a group of chest-slapping male mountain gorillas in Africa in 1978.

VELTMAN: ...The 263 noises of destruction...
(SOUNDBITE OF GLASS SHATTERING)
VELTMAN: ...Or the archive's 373 comedic effects...
(SOUNDBITE OF SPRING VIBRATING)
VELTMAN: ...Definitely costs time.
(SOUNDBITE OF HORN HONK)
VELTMAN: Chloe Veltman...
