The rise of remote and hybrid work has increased the need for wearable communication devices that keep the user’s voice clear while reducing background noise in open and shared office spaces. Open-plan offices can be challenging because multiple people talking at the same time and sound reflections from surfaces can make voices harder to understand. Existing research and patents have introduced different methods for voice capture and sound isolation through systems like WhisperMask and smart soundproof masks but these methods still lack the ability to combine material-based sound dampening with multiple connectivity options. The existing solution needs a compact design which provides comfortable use and total sound isolation for its users to use as a speech isolation device which supports multiple communication methods. The study created a Microcontroller-Based Mask with Acoustic Dampening System which protects privacy through its multi-layer design that uses a detachable tri-mode microphone system for wired Bluetooth and 2.4 GHz communication. The researchers used the Waterfall Model to create a prototype which combines sound-absorbing foams and fabric layers and detachable microphone housing that uses magnetic attachment for simple operation. The experimental testing results demonstrate that the prototype reached an average sound reduction of 10 dB which resulted in the perception of loudness being reduced to half while the system maintained Signal-to-Noise Ratios (SNR) between 11 dB and 18 dB across different testing environments which provided excellent voice clarity. The device testing results show that the device successfully reduced voice leakage while enhancing speech understanding for people in noisy environments which makes it an effective solution for people who want to keep their conversations private in public areas. The study advances wearable acoustic technology development which supports UN Sustainable Development Goals 3 (Good Health and Well-Being) and 9 (Industry, Innovation, and Infrastructure) through its development of innovative human-centered audio technologies for upcoming work environments.
