Smartear is a comprehensive smart device and mobile companion app, designed to track noise pollution within cities.
Noise pollution affects both health and human behaviour. Unwanted sound can create psychological and physiological damage. In doing so, can result in noise-induced hearing loss, hypertension (high blood pressure), tinnitus (hearing ringing when no sound is present), and an increase in stress levels.
APPROACHING THE PROBLEM
I was challenged in creating a custom visualization where the user would easily be able to identify their city's noise levels. After doing research on how to measure sound I began experimenting with different visualization methods.
Initial concepts and designs for the data visualization and interface.
Experimenting with both the colours scheme and visual design to best represent the data.
When selecting the 'i' icon in the top right, the user can see how the visualization works and what the gradient represents inside each circle.
VARIATIONS OVER TIME
The user can see the trends from various weeks and months by clicking the arrows on either side of the dates. As well, the user can search a new city, using the search icon in the top right.
By selecting a line on the graph, the user can view what is causing the noises and its intensity.
The user can view the cities around them and see how intense or muted the noise trends are in that area.
By selecting on a circle the user can search cities to compare to. As well as, view the cities for daily, weekly, or monthly trends.
When selecting the 'i', the user can see how a mix between dark purple and light purple identifies their city as average. It states that an average residential area has a Decibel score of 40. When the user selects a circle the scores are evealed.
