Automatic Gain Control Microphone
John Hayden Colvin
OVERVIEW
This project focused on developing a functional microphone system with automatic gain control to maintain consistent audio output in varying noise conditions. As a member of the mechanical engineering team, I designed the microphone housing and evaluated physical materials to improve acoustic performance while protecting internal electronics. The enclosure was optimized for ergonomics, manufacturability, and noise reduction through iterative CAD modeling and hands-on testing.
HighlightS
- Designed a custom microphone body using parametric CAD modeling
- Created internal mounting geometry for secure component placement
- Fabricated and tested a pop filter to minimize plosive sounds and airflow noise
- Evaluated multiple cover materials for acoustic dampening and clarity
- Balanced noise reduction with sound fidelity through design iteration
- Implemented physical testing results into updated CAD designs
- Collaborated closely with the electrical team for system integration
