The hEARo application has been created to promote hearing tests in children, teach them to respond to a sound stimulus and, by means of a game, test children's hearing. Our game is primarily aimed at parents and nursery schools. With our application, a parent or other guardian may notice the child's hearing problem. Performing hearing tests in children on everyday basis, we know well how difficult it is to do the audiometry test in children below 5-6 years of age. We wanted to create a game that will make children interested and at the same time the result of the game will be a certain tip for parents.
