About the role#
This PhD internship focuses on improving audio performance in next-generation wearables. You will work with the Hardware Audio Team to ensure small speakers deliver high-quality sound. The project is open-ended, allowing you to help define the most impactful research directions alongside our engineers and researchers. Internships last between 12 and 24 weeks with various start dates available.
What you'll do#
- Develop and validate methods to drive speakers to their full capability.
- Research how speaker performance changes across different units and operating conditions.
- Connect improvement opportunities to end-to-end audio quality metrics.
- Design and run experiments in audio labs and analyze the measurement data.
- Collaborate with teams across audio hardware, tuning, and algorithms.
- Share your findings through documentation, presentations, and potential publications.
What you'll need#
- Current enrollment in a PhD program for Acoustics, Electrical Engineering, Mechanical Engineering, Physics, Digital Signal Processing, or a related field.
- Research experience in electroacoustics, loudspeaker modeling, or audio signal processing.
- Proficiency in Python or MATLAB.
- Experience with audio hardware measurement tools like precision microphones, anechoic chambers, or HATS.
- Strong documentation and presentation skills.
- Intent to return to your degree program after the internship.
- Ability to maintain work authorization throughout the internship.
- Experience with large-signal or thermal loudspeaker behavior is a plus.
- Familiarity with transducer characterization tools such as the Klippel Analyzer System, laser vibrometry, or Audio Precision.
- Knowledge of DSP building blocks like digital biquad filters, IIR, FIR, and multi-band DRC.
- Experience with acoustic simulation software like COMSOL or psychoacoustic metrics.
- Ability to apply AI tools to acoustics and signal processing fundamentals.
- A track record of research published in journals or conferences like AES, ICASSP, or JASA.
Location & details#
- This is an on-site role based in Sunnyvale, California.
- The position is full-time and paid.
- Start dates are rolling throughout the year.
