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!
Third graders showed off their sound technologies by demonstrating how they worked in front of their fellow acoustical engineers. They had to make sure they showcased how they met the criteria of the challenge--that their sound technologies could change in both pitch and volume. Way to go third graders...I mean acoustical engineers!
