Sound Uncovered

By Exploratorium

Open iTunes to buy and download apps.


Explore the surprising side of sound with Sound Uncovered, an interactive book featuring auditory illusions, acoustic phenomena, and other things that go bump, beep, boom, and vroom.

From the makers of Color Uncovered—the Exploratorium—this app puts you at the center of the experiment: Hear with your eyes, see with your ears, make and modify recordings, test your hearing, and more.

How do you make a saxophone growl? Are there secret messages in music played backward? Why does the sound of gum chewing drive some people mad? Listen up and find answers to these questions and more as you take an auditory trip to the place where sound gets truly interesting: the space between your ears.

Find more to explore from the Exploratorium online at Better yet, visit us in person at our new home at Pier 15 in San Francisco, California.

***Tip for users with sound playback issues: make sure the side switch on your iPad is not set to mute. (This is separate from the volume control.)

The Best thing I've found yet

I have literally every kind of app on my ipad and nothing compares to this. This is not only actually enjoyable in the long term (as in the enjoyment isn't just contained to when you're using it, it keeps you interested and involved even when doing other things - unlike games where the involvement has to be satisfied by constant use). It also is educational and is a revolutionary way to learn - much better than textbooks!
If you are not sure whether to download this go ahead! You will not regret it and if you do (for some strange reason) find yourself not enjoy using this bit off app-gold you will be left with some unique and interesting knowledge to use in your life.

Great fun

The initial problem I had with no sound on iOS 8 is a feature (i.e. bug!) in iOS that affected some other apps. That's now fixed and I had some good fun with this, some of which was new to me.


A fantastic resource that can be used in schools. It shows what the combination of the i-pad and imagination can achieve.
