This project compares test subjects' responses to whining and other "attachment" and attention-getting sounds to determine which sounds are most distracting.

This experiment investigates whether there are certain sounds that affect men and women differently

This science fair project idea produces sounds by creating vibrations using different objects.

In this activity, you'll send your kindergartener on a scavenger hunt to find sounds and create a sound recording. Here's how!

How does a kazoo, the strings of a guitar, or the speaker of a radio make sound? The purpose of this science fair project is to show how vibration makes sound.

Demonstrate how we are able to locate sounds, echolocation. Have a blindfolded subject locate you by the sound of your clapping.

Science fair project that examines what causes thunder and why a thunderclap sounds so loud. How is lightening related to the creation of sound waves?

In this project students determine which instruments composers use to create birdsongs and birdcalls in classical music.

Find out the differences (if any) in the frequencies of voices produced from a computer, from a phone, and directly coming out of the voice box of a human.

This science fair project idea produces varying pitches of sound.

This project determines what percentage of test subjects react adversely to the sound of fingernails on a chalkboard and explores their physiological responses.

Find out if most people can distinguish the difference between tones on different instruments.

Take a closer look at your furry friend (or the furry friend of a neighbor -- with permission) to discover if communication exists between cats and humans.

Little scientists will make inferences about hearing loss, pitch, and frequency in this great science fair idea that puts the human ear to the test.

This project explores whether similar type movie scenes are accompanied by music with similar characteristics.

Learn about sound physics and do a survey experiment to explore the difference between sound and noise in this science project.

This play-activity causes young children to focus on and become more aware of their sense of hearing and the power of their ears.

Show your middle schooler how a quick whirl of spinach in the blender will reveal the cobwebby "stuff"--or DNA--of life!

Discover whether different amounts of water added into a wine glass will produce a different pitch when their fingers are rubbed along the rim.

This science fair project idea examines if there is a reason that musical notes are at the pitches they are.

Research camouflage products and techniques, test quality by timing volunteers. Calculate the average length of time to recognize the subject.

Learn how to be a bird scientist in this simple project of watching feathered friends in their habitat.

What is the Doppler Effect, or the Doppler Shift? The purpose of this science fair project is to determine how distance impacts the Doppler Effect.

How good are humans at sound localization? Kids can try this cool science fair project idea to see how good their friends are at judging sound direction.

In this project, waves of vibrations are experimented with using water in glasses.

In this science fair experiment, students learn about the scientific principles behind Doppler ultrasound.

How does the size of a vibrating surface affect the pitch of a drum? Learn about drum size and pitch with this easy science fair project idea.

A fun, life science sxperiment idea idea involving strategies for keeping birds away from crops using a distress call. What kind of distress call works best?

Are you able to endure long periods of exercise? Find out if snorers can exercise longer than non-snorers.
