We don't carry out or encourage online hearing tests. Any we have come across can be very misleading and are usually a name and detail source for the marketing departments of the companies who offer them. Any accuracy will be depending on the level and quality of your speakers or headphones. If you are worried about your hearing you can come in to Dublin Hearing Aid Centre, we will offer you free hearing screening, and a full hearing test if we feel you need it. You will have the reassurance that what we are doing is not guesswork.
