If you have had a hearing test in the last 12 months that indicates that you need a hearing aid, the answer is YES! TIP: When you visit an audiologist, always ask for a copy of your hearing test results, including the audiogram. Having copies of test results will make it easier to shop around to find the best deal. More tips from the Australian Consumer Commission.
In cases where someone has hearing loss in one ear and normal hearing in the other, just one hearing aid on the side with the hearing loss is okay.
