The parents' guide to what's in this app.

Educational Value

Kids can learn about acoustic phenomena, auditory illusions, and how the human brain affects the way we process sound. Through virtual experimentation and detailed, illustrated explanations, kids explore beat waves, echolocation, sound engineering, dichotic melody, the refraction of sound, and much more. Many of the topics are somewhat complex, so kids would benefit from background knowledge of the basic properties of sound. An interactive glossary would be a nice addition. Sound Uncovered is a fascinating, free science resource that would be a great addition to any virtual library.

Ease of Play

Large, easy-to-read graphics and a simple layout make navigation easy. 


The Exploratorium museum and one of its other apps are promoted at the end of the table of contents.

What's it about?

Kids start by choosing from 15 topics in the table of contents. They can choose the first topic, the last topic, or anything in between. Most of the topics include an interactive experience followed by a "What's Going On?" article. For example, in Find the Highest Note, kids tap keys in a clockwise direction and try to identify the highest note. When they tap on the question-mark icon at the bottom of the screen, an illustrated article pops up and describes the sound phenomena.

Is it any good?

SOUND UNCOVERED is a fantastic way for kids to explore interesting phenomena related to sound. The interactive pages answer questions about sound and the brain that kids of all ages will find fascinating. Kids can test their speech-recognition skills, learn how temperature plays tricks with sound, investigate the relationship between visual and audio perception, and more. This free educational resource makes a great addition to any virtual science library.
