Project Summary
Designed a wearable low-frequency hearing aid to reduce overwhelming sounds for individuals with sensory processing disorders and autism.
Developed a device that selectively reduces disruptive noises while maintaining environmental awareness.
Combined hearing aid functionality with headphone ergonomics for daily usability.
Goals/Requirements
Reduce the impact of unfamiliar and excessively loud noises that can affect focus and comfort.
Allow users to identify and adjust which sounds should be reduced.
Create a compact, wearable design that conforms to different head sizes.
Manage heat generated by electronic components to prevent discomfort or skin damage.
Incorporate a sheet metal component as part of the design.
Outcome
Developed a headphone-style configuration using an Arduino Uno, microphones, speakers, battery charger, lithium-ion battery, and Bluetooth module.
Designed a rear headband housing to contain wiring and electronics while maintaining adjustability.
Integrated a sheet metal heat sink to redirect heat away from the user's head.
Modified the earbud design to incorporate microphones and improve functionality.
Used rigid plastic components to minimize deformation and maintain structural stability.
Verified component fit through SolidWorks tolerance analysis and evaluated structural performance through FEA.
Conclusion
Demonstrated the potential of wearable technology to support individuals with sensory processing challenges.
Created a customizable hearing assistance device that balances sound reduction, comfort, and usability.
Identified opportunities for future development through improved sound filtering algorithms and further user testing.
Validated the mechanical design through simulation, showing minimal deformation and no component interference.
