Each and every day, every one of us interacts with different sounds. These sounds can serve as a way to communicate, to inform, or to annoy us! Acoustical engineers help develop technologies that are focused on sound and are sound experts. They know about pitch and volume and how to change factors that affect these properties. Whether they work to amplify sound or to dampen it, their work is very important to us!
With their plans approved, third graders are building their sound technologies, making sure they change in both pitch and volume as was required by the criteria of the challenge. Check out their amazing work...we'll be able to test them in front of a crowd soon to see if they meet the goal of the challenge...to get people's attention in the sometimes noisy cafeteria!
