The Oshman Engineering Design Kitchen (OEDK) is the largest makerspace at Rice University, providing a space for all students to design and prototype solutions to real-world challenges. To serve this purpose, the OEDK houses a number of power tools and large machinery that produce loud, potentially unsafe noises. While the OEDK has successfully established a
