Sound

Need some white noise to help you sleep? You’re in luck:

White Noise 7 is out, and wants to be like Instagram for restful sounds.

When the White Noise app first went live in 2008, it went from being one of the first mobile apps to go live in the Apple store to the number one app in the fitness and health category.  Eight years later and the White Noise app remains popular and now allows users to upload sounds from around the world.  White Noise 7 is ad-supported, so no cost to download.

Can Sound Kill You?

The short answer is “yes,” theoretically.  The long answer, thankfully, is that “it would be difficult, and perhaps impossible, to artificially generate a noise loud enough to kill a person.”  Wondering how loud a sound must be to kill and how sound alone could kill a human?  Here are your answers:

[I]’s been speculated that 195 decibels would do the trick. (By comparison, normal conversation registers at 60 dB; an ambulance siren at 10 feet is about 115 dB). At that volume, air pressure fluctuations would be severe enough to damage your lungs, creating lethal air bubbles in the blood or simply causing the lungs to pop like balloons.

Now you know what your nightmare will feature tonight!
