Ship Blasted Pirates With Sonic Weapon
This is hellacool. The cruise ship attacked by Somali pirates used a "sonic weapon" to help ward them off. Basically the weapon directs a tight-beamed, very loud, smoke alarm-type tone at its target.
The article says smoke alarms are at 80 db and this weapon is at 150 db.
Here's a link to the Noise Center for comparison. This table shows 150 db is as loud as a jet engine taking off.
FYI. The loudest rock concert ever was at 126 db by the Who (see article). Note: 3 minutes 45 seconds of 130 db noise can result in permanent hearing loss.
Anyhow...after reading the article, I'm getting a new car horn...
