Portable Soundproof Booth for Vocal Training

Made a mask able to reduce sound intensity by 15dB and greatly suppress frequencies of 1-5kHz

I like singing and used to do vocal training every day. However, after I moved to NYU’s residential hall, I was not able to project my voice as confidently as I was at home because I received some noise complaints at the beginning of the semester.

This is a personal engineering project affiliated with the NYU prototyping fund 2021 Fall cohort. A 3d scanner app for iPhone, EM3d was used to capture the geometry of my face. Blender was used for mesh modeling. Solidworks computational flow dynamics were used for noise prediction and optimization. Pepakura Designer was used for mesh unfolding. And a laser cutter was used for production.

Tested in two experiments. The final design was able to reduce the sound intensity in the environment by 15dB and suppress frequencies sensitive to human hearing.
