Bone Conduction Headset for xEMU

Problem Statement: NASA's new spacesuit, the xEMU, features embedded speakers and a microphone, replacing the old communication cap. However, this system causes echoing issues, as audio from the speakers is picked up by the microphones. Bone conduction headphones are being tested as a solution, aiming to combine them with over-the-ear protection to safeguard astronauts' hearing from suit noise. The design must ensure clear communication and comfort during long extravehicular activities (EVA) Objective: The objective is to design an over-the-ear bone conduction headset that protects the astronaut’s hearing from noises generated inside the space suit while allowing clear communication through an 8-hour EVA.
