PHILADELPHIA (CBS) – On today’s APP-tastic and Outta SITE – Sound Uncovered.
We tend to have a lot of fun with optical illusions, but the world of sound can be just as fascinating.
Sound Uncovered lets you dig deeper into the audio world, letting you play lyrics backward and discover whether you actually can talk and listen at the same time.
You’ll also learn exactly why someone smacking their gum is so darned annoying.
Check out the Sound Uncovered app.
