Kids Tech University at Denison
Dr. Sarah Wolff and 5 Denison students – Kirsten Audette, Maddie Boster, Lamine Diakite, Mara Kilgore, and Nick Staniszewski– recently hosted over 50 local-area fourth-graders for Kids Tech University at Denison University. Dr. Wolff presented Why does it sound like that? During this very hands-on and ears-on activity, Dr. Wolff taught the students how sound travels from an instrument to their ear, how to ‘visualize’ sound, and what it really means, mathematically, to be a musical note. The fourth-graders even built their own musical instruments to play the exact notes of their choosing. Interestingly, this work is closely tied to Dr. Wolff’s own area of research, which uses a generalization of classical discrete Fourier transforms, one of the main tools for decomposing and understanding sound waves.
