Preserving the Soundscape: Exploring ways to mitigate sound pollution in Acadia National Park

This project, performed within Acadia National Park, assessed sources of noise pollution and provided the park with methods for reducing noise. Based on previous studies conducted by the National Park Service, the project team recorded noise levels in the most popular locations within Acadia, analyzed the resulting data, and identified human voices as the most significant sources of noise. Using this information, the team was able to test a Quiet Zone within the park and in doing so achieved a 26.4% reduction in human noise

Assistive Guitar Plucking Device and User Interface

The goal of the project was to develop a wireless, battery-powered device with a plucking mechanism and a wearable user interface (UI) that would enable individuals with physical disabilities to play a guitar. The plucking mechanism, mounted to an adjustable frame around the guitar, has 3D printed plectra to actuate each guitar string. The inertial measurement unit based UI is comprised of two wearable devices that calculate which strings to pluck, by using sensor fusion to track user motion and device orientation. Music provides people an avenue to express their emotions and has been shown to stimulate the brain in uniquely beneficial ways. This project provides an opportunity to create music for individuals who have not previously had access to this experience
