Infographic: How the world hears

Source: Mimi Data
This year, to celebrate and raise awareness around World Hearing Day we cereated the How the World Hears Index.  It measures how well nations are doing at maintaining healthy hearing ability. 

We took our data - drawn from the Mimi database, the world's largest repository of healthy hearing stats, and broke it down to calculate a “Mimi average” hearing capacity (ie the mean of all hearing tests from the last year), and then compared geographic regions to this average. For the world-wide average, we did two geographic comparisons: cities of the world, and countries of the world.

We limited the number of cities and countries/states based on the number of “clean” data sets in our data bank to ensure statistical significance and accuracy. The average hearing capacity /  Amount (in dB) that this location’s average hearing capacity (PTA-4)  grouped into different colours - from better to worst hearing ability.
