NASA Human Lander Challenge: Noise Suppression and Control

The objective of this project is to design a solution to mitigate noise from the Environmental Control and Life Support System, which hinders astronaut communication and long term habitation in space.

Our current solution is a modular acoustic barrier system that consists of a lattice-like structure of parallelogram-shaped panels. Electrical actuators will adjust the panel to the optimal geometry based on the target frequency received by a sound sensor module

At the current point in time, I have:

  • Performed calculations to determine the range of frequencies that can be mitigated by our panel

  • Determined the target functional range of the angle of attack of our deflection shapes

  • Developed a functional CAD model

  • 3D printed a concept prototype for a Preliminary Design Review to our sponsor
