The Smallest of Sounds

Friday, February 15, 2008

A recent posting of mine here was about the sound of our Earth, sped up 10,000 times. The actual largest terrestrial sound possible. Well, this is a posting about the smallest terrestrial sound possible; the “sound” made by molecules. This post writes about this post from World Science magazine, which starts off by saying:

Phys­i­cists say they’ve recorded tiny vibrations of in­divid­ual mole­cules, that could be called sounds “de­pend­ing on how you de­fine sound” and put them in au­di­ble form.

You can hear the sound, here. But I doubt it actually “sounds” like that.
