sNAP Overview

Any means of reducing the sound pressure with respect to a specified sound source and receptor. In this case, low-frequency noise caused by diesel engines and high-frequency noise caused by car horns would be tackled seperately.

A random signal having equal intensity at different frequencies, giving it a constant power spectral density. White noise creates a buffer between outside noise and eardrums, blocking out outside sounds and masking disruptive sounds.

sNAP tries to minimize the circumstances in which user has to frequently check their mobile devices. Staring at digital screen for long time would cause difficulty falling asleep. Therefore, a controller, with comfort ergonomic designs, is used.

Milimeter wave (mmWave) radars transmit electromagnetic waves and any objects in the path reflect the signals back. The signals include four primary vital signs: body temperature, blood pressure, breath rate and heart rate, which reflect sleep quality.

The sNAP App would visualize sleep data, provide sleep quality ratings, and suggestions for users. Users could also use it to set up alarm clock. The APP adopts Greyish Cyan Theme which establish senses of sleep both physiologically and psychologically.
