Worried your hearing might be getting bad but don't want to see a doctor about it just yet? You can give yourself a preliminary test using mobile apps to see where you stand.
BBC Future recommends a couple of different apps, Hearing Test for Android and UHear for iPhone. You can also test your hearing age using Mimi Test for iPhone (this video also works). Both will give you an idea of how your hearing is doing so you can make the choice of whether or not it's worth seeing a doctor.
