Refrigerators To Cool With Sound (Cool!)
T-Kir writes "A very interesting report from the BBC where researchers at Penn State University are developing a prototype fridge that cools using metal plates and sound waves. If successful, this technology would help remove the dependance on gases that contribute to global warming. Talk about Cool!"
hey, no troll! I'm serious.

Vhaaat a kuunntreee!
One future, two choices. Oppose them or let them destroy us.
Now when there's farting sounds in the room, I can point to the fridge when my wife gives me a scornful glance.
Decibels aren't on a linear scale. Your 53db is a logrithmic difference. Every 3db in difference is a doubleing of intensity. 123db is twice as intense as 120db. So 53/3 = 17.6667 which means 173db is 2^17.6667 times as loud as 120db. Which is actually 208063.83 times as loud. Which means the article was still wrong. Here's a link about decibel math: here.
The next remark is false. The previous remark is true.
