This educational exhibit shows how the hearing changes with age. You can examine your hearing and determine the “age” of your ears. The sound frequency is changed with a large slider. The slider should be swiped to the right, towards the higher frequencies, until you stop hearing a sound. On the scale along the slider there is a reference age. Our part was to provide the software, a microcomputer and an arduino based interface, along with assembly of the components.
