Job DescriptionIn this Electro-Acoustics EngineeringCo-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 DoGet Hands-On in the LabYou'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 ProblemsGreat 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 LearnBy 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.
- Loudspeaker design: Thiele/Small parameters and their application to loudspeaker systems.
- Signal processing: Analog and digital filters, Fourier analysis, frequency- and time-domain analysis, digital signal processors, and frequency-response manipulation.
- Programming & automation: MATLAB, Simulink, LabVIEW, Python, and related engineering tools.
- Electro-acoustic engineering: Understanding the interaction between electrical, mechanical, and acoustic systems.
- Simulation: Acoustic, mechanical, and electro-magnetic modeling.
- Crossover design: Passive 2-way and 3-way loudspeaker crossover networks.
- Thermal sciences: Heat transfer, fluid dynamics, and thermal behavior of audio components.
- Mechanical design: CAD, assemblies, drawings, prototyping, and basic woodworking.
- Test & measurement: Microphones, impedance measurement, data acquisition, anechoic measurements, and laboratory test methods.
- Professional audio systems: PA systems, mixers, effects, DJ equipment, live bands, and sound reinforcement.
QualificationsWhat We're Looking ForWe're looking for students who are curious, hands-on, analytical, and genuinely excited about audio.
Strong candidates will have experience or coursework in several of the areas above. You don't need to know everything on day one-we expect you to learn. What matters most is that you're excited to understand how things work, why they work, and how to make them better.
Particularly valuable qualifications include:- Engineering students at a Sophomore, Junior, or Senior level
- Familiarity with Thiele/Small parameters and loudspeaker design.
- Programming experience with MATLAB, Simulink, LabVIEW, Python, or similar tools.
- Experience with live sound reinforcement, PA systems, DJ equipment, mixers, effects, or live music.
- Strong critical listening skills and an interest in music production, recording, mixing, mastering, or loudspeaker evaluation.
- Knowledge of signal processing and frequency/time-domain analysis.
- Experience designing passive crossover networks.
- Familiarity with thermal sciences, heat transfer, or fluid dynamics.
- CAD experience and an interest in mechanical design.
- Hands-on experience with woodworking, hand tools, soldering, wiring, or building things.
- An analytical mindset and the ability to turn a confusing test result into a solvable engineering problem.
Most Important: Bring Your Passion for AudioWe're especially interested in students who don't just love music or audio-they're curious about it.
Come spend two semesters with us, and leave with the experience of having helped create something!
