You've chosen a hearing aid. Make sure you understand the features of the aid you're buying. This includes the trial period, the warranty, and the return policy. You'll then start the process of having it fitted. The hearing aid will be custom-made for you. A special graph of your hearing loss (audiogram) will be used as a guide.

The hearing aid must be fitted to the shape of your ear. A bad fit can cause sound feedback. It can also cause irritation in the ear canal. A mold of your ear canal may be made. This is painless. The audiologist or hearing aid specialist will put a soft material into your ear. It firms up in a few minutes and is easily removed. This creates a mold of your ear. The mold is then sent to the company that will make your hearing aid.

When your hearing aid is ready, the fit will be checked. To get ready for the fitting, make a list of questions you have about your hearing aid. Having your questions in writing will help you remember them. The audiologist or hearing aid specialist will make sure it feels comfortable in your ear. The aid will be checked to make sure it works correctly. Tests will be done to check your ability to hear sounds while wearing the aid. After the hearing aid is fine-tuned, you can start wearing it. Ask for instructions about how to care for it. It's important to keep hearing aid batteries out of reach of children and pets. They can be deadly if swallowed.
