The integration of a laser vibrometer into the "Sounds of Science" courses at both the Missouri Scholars Academy and the University of Missouri Honors College has significantly transformed the student learning experience, making bioacoustics more accessible and engaging. Polytec’s advanced equipment has enabled students to explore and analyze substrate-borne vibrations in innovative and inspiring ways.
This past summer, students engaged in hands-on experiments where they recorded and studied the vibrations produced by various insects, such as caterpillars chewing on tomato leaves and treehoppers walking and singing. These practical experiences brought a new level of excitement to the classroom. One student shared, “Seeing the vibrations from a caterpillar's bite on the screen was mind-blowing! It made me realize how much is happening in the natural world that we can't see or hear with our own senses. I never thought I'd be this excited about science, but using the vibrometer to actually 'hear' insects communicating was incredible. It made everything we learned in class feel so real and relevant.”
The course design, which emphasizes accessibility and engagement, was further enhanced by these practical applications. Students not only grasped complex concepts more easily but were also deeply engaged with the material. "The vibrometer made me feel like a real scientist, discovering things no one else might notice. It really pulled me into the world of bioacoustics," said another enthusiastic student.
The precise data collected during these experiments provided students with valuable insights into the complex ways organisms interact with their environment. This experience not only increased their understanding of bioacoustics but also inspired several to consider further studies and careers in science. "The use of the laser vibrometer has elevated the educational experience in these courses, providing students with the skills, excitement, and inspiration to continue exploring the world of science. I was thrilled to teach students how to use the laser vibrometer. It’s not every day you get to bring such cutting-edge tools into the classroom, and seeing the students’ excitement and engagement made it all worth it," said Sabrina Michael, Ph.D., Assistant Professor, Honors College, University of Missouri.
The introduction of the laser vibrometer into these courses represents a significant step forward in making scientific exploration both accessible and thrilling, ensuring that students not only learn but are inspired to pursue further knowledge in the field of bioacoustics.
About PolyLab Education Program
The PolyLab Education Program empowers students with cutting-edge tools for vibration measurement, offering hands-on experience with industry-level technology. This program, available as either a short-term loaner for up to 6 weeks or as an extended access option for up to 2 years, includes a comprehensive educational kit with test objects and detailed tutorials. PolyLab bridges the gap between basic lab tools and advanced vibro-acoustic studies, preparing students for careers in fields requiring sophisticated understanding of vibration and modal analysis.
