Learner Outcomes, Activities and Assessments

Learner Outcome	Activity (optional)	Assessment
Develop mathematical models of sound radiation, outdoor propagation, and structural vibration	In class group activities and homework assignments.	Graded homework and exams.
Solve problems in acoustics using the following mathematical techniques: differential equations Fourier analysis eigenvalue equations complex variables	In class group problem-soving and homework assignments.	Graded homework and exams.
Predict the behavior of vibrational and acoustic systems using computational methods.	Working in groups, students will modify existing programs written in Matlab and Mathematica to investigate complex wave behavior.	Student groups present the results of computational mini-projects in class. Rubric completed by instructor and peers.
Design, set up, and evaluate acoustics and vibration measurement systems.	Working in groups with instructor supervision, students complete five two-week laboratory experiments using a Scanning Laser Vibrometer, the anechoic chamber, modal analysis equipment, precision microphones, and the Labview data acquisition system.	Student groups submit a formal lab report for each experiment. Rubric that addresses appropriate and safe use of equipment, quality and understanding of measurements, and effectiveness of communication.
Analyze measurement data with signal processing tools.	For three of the five group lab experiments, students will perform one or more signal processing tasks, including filtering, Fourier transforms, and cross-correlations.	Student groups submit a formal lab report for each experiment. Rubric that addresses quality of analysis and effectiveness of communication.
