Measuring Your Threshold of Hearing for Sounds of Different Pitches Print E-mail

Grade Level: 7 - 9

If you're interested in doing a project about how we hear, this is a good one for you. With this project, you'll do background research and make measurements to understand how the sensitivity of your own hearing varies with the pitch of the sound.
