Consider going to a doctor. An Ear, Nose, and Throat physician (also known as an ENT or otolaryngologist), can administer a medical exam. The exam will rule out any medical reason for your hearing loss which would require medical or surgical treatment. Your doctor can also give you a referral to an audiologist or a hearing aid dispenser if your health plan requires a doctor's referral for services.
Consider going to an audiologist. An audiologist will perform an audiological exam to determine the type and amount of your hearing loss, and will counsel you as to your non-medical options to improve your hearing loss.
Buy your hearing aid either direct-to-consumer, or from a licensed hearing healthcare professional (audiologist, a hearing aid dispenser, or an ear, nose, and throat physician). Ask your hearing healthcare professional to help you determine what features you will need.
Select your hearing aid carefully. Select one that is convenient and easy for you to use. Buy hearing aids with features that meet your needs in daily listening activities.
Be sure you know how to care for your hearing aid. Ask a hearing healthcare professional to show you how to clean it and replace the batteries at the time of purchase.
Ask about a trial/adjustment period. Most manufacturers provide a trial/adjustment period during which your hearing aids can be returned for a refund. A trial/adjustment period will allow you to test out your hearing aids to see if they work well for you.
Check out the warranty. Like any other product you purchase, be aware of what parts or services are covered by the warranty.
