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