In this Electro-Acoustics Engineering Co-Op, you’ll work side-by-side with experienced design, development, and research engineers to help create the next generation of professional loudspeakers and audio systems. Over two consecutive semesters, you’ll get hands-on experience with the entire product-development process—from the first prototype and lab measurement to analysis, troubleshooting, refinement, and ultimately bringing a market-leading product to life.
This isn’t a co-op where you spend your days watching from the sidelines. You’ll be in the lab, building, measuring, analyzing data, and solving problems.
Your work may revolve around a primary engineering project, but you can expect plenty of variety along the way. Every day can bring a new technical challenge, experiment, or opportunity to learn something different.
What You’ll Do
Get Hands-On in the Lab
You’ll work directly with loudspeakers, test equipment, prototypes, and the systems used to evaluate professional audio products.
Constructing and modifying prototype loudspeaker systems.
Performing acoustical, electrical, mechanical, thermal, and materials testing.
Designing and building new test systems, including hardware, software, data acquisition, and measurement setups.
Maintaining, troubleshooting, and repairing existing test equipment and systems.
Soldering, wiring, assembling components, and making mechanical repairs.
Assembling loudspeaker cabinets and moving loudspeaker systems between test rooms and facilities.
Performing acoustic measurements using microphones, anechoic chambers, impedance measurement systems, and other specialized equipment.
Setting up experiments and figuring out creative ways to measure things that don't have an obvious measurement method.
Analyze, Simulate & Solve Problems
Great audio engineering isn't just about hearing the difference—it’s about understanding  why  there is a difference.
Analyze acoustic, electrical, mechanical, and electro-magnetic test data.
Use simulation tools to predict and understand loudspeaker performance.
Troubleshoot unexpected test results and determine their root causes.
Create and modify mechanical designs using CAD.
Produce mechanical drawings and documentation.
Support product development, engineering validation, and industrialization activities.
Research electro-acoustic technologies and investigate new approaches to loudspeaker design.
Research international standards and industry validation methods.
Use programming and data-analysis tools to automate measurements, process data, and make engineering decisions.
What You’ll Learn
By the end of the co-op, you’ll have experience with far more than textbooks and classroom theory. You’ll gain exposure to the complete professional loudspeaker development process and learn how engineering concepts become real products.
