The Quiet-o-Meter is an interactive sound awareness prototype designed to promote mindful noise behavior in shared environments. Inspired by the need for greater awareness of how our collective sound levels can affect others, this project transforms ambient noise into visual and auditory cues that encourage quieter, more considerate spaces.

Built on an Arduino platform using a Grove Sound Sensor, an OLED display, LEDs, and a buzzer, the system continuously measures the intensity of surrounding sounds. It then translates this information into three feedback levels: a single LED activates at moderate sound, a “Quiet please” message appears as noise increases, and finally, an audible alert is triggered when the sound becomes excessive.

The Quiet-o-Meter is particularly suited for open offices, classrooms, or shared meeting spaces where simultaneous conversations or online calls can easily escalate background noise. By providing immediate feedback, the system helps users self-regulate without external enforcement, fostering an atmosphere of awareness and respect.

This prototype serves as both a functional tool and a conceptual statement on the importance of acoustic comfort in collaborative environments. It demonstrates how simple, accessible technology can translate data into social awareness, turning invisible sound energy into a shared, tangible experience that benefits everyone.
