What You'll Find Here
This page answers the questions people ask most often about hearing aids — how they work, what they cost, where to get them, and what happens after you buy one. These are the things that come up repeatedly when someone is thinking about whether a hearing aid is right for them.
The answers here are based on how hearing aids actually function and what the process looks like in practice. If you have a question that isn't covered, your audiologist or hearing aid provider can give you an answer specific to your situation and your hearing loss.
Key Takeaways
- Hearing aids amplify sound and send it into your ear; they work best for people with sensorineural hearing loss (damage to the inner ear) and less well for conductive hearing loss (blockage in the outer or middle ear).
- Cost ranges from under $1,000 to over $6,000 per pair depending on the technology level, and most insurance does not cover them, though some Medicare Advantage plans and state programs do.
- You need a hearing test from an audiologist or your doctor before you can be fitted, and the fitting process usually takes multiple visits over several weeks.
- Hearing aids require daily cleaning, battery changes (or charging), and adjustments as your hearing changes or as you get used to wearing them.
- If a hearing aid doesn't work for you, many providers offer a trial period of 30 to 45 days where you can return it for a refund.
How Do Hearing Aids Actually Amplify Sound?
A hearing aid has three basic parts: a microphone that picks up sound from the environment, a computer chip that processes and amplifies that sound, and a speaker (called a receiver) that sends the amplified sound into your ear canal. The chip is programmed to amplify certain frequencies more than others based on your specific hearing loss pattern, which is why the fitting has to be customized to you.
Modern hearing aids also have noise reduction features that try to separate speech from background noise, directional microphones that pick up sound better from in front of you than from behind, and wireless connectivity so they can work with your phone or television. The more advanced the chip, the better these features work — but they also cost more.
Hearing aids do not restore normal hearing. They make sound louder, but they cannot fix damage to the inner ear or restore the clarity you had before hearing loss. Some people hear much better with them; others find them helpful but not life-changing. This is why a trial period matters.
What Types of Hearing Aids Are There, and What's the Difference?
Hearing aids come in several styles, and the main difference is where they sit and how visible they are. Behind-the-ear (BTE) models hook over the top of your ear and have a tube that runs sound into your ear canal — they are the most powerful and easiest to handle. In-the-ear (ITE) models sit in the outer part of your ear. Completely-in-canal (CIC) models sit deep inside your ear canal and are nearly invisible, but they are smaller and harder to adjust.
Receiver-in-canal (RIC) models are a middle ground: they sit behind the ear but the speaker sits in the canal, so they are less visible than BTE but more powerful than ITE. Invisible-in-canal (IIC) models are the smallest and most expensive. Your audiologist will recommend a style based on your hearing loss severity, your ear shape, your dexterity (how easily you can handle small objects), and your budget.
The style affects price, power, battery life, and how much maintenance they need. Smaller models need smaller batteries and charge more often. Larger models are easier to put in and take out, and they last longer between charges.
What Does a Hearing Aid Cost, and Will Insurance Pay for It?
Hearing aid prices vary widely. Basic models start around $500 to $1,000 per ear, mid-range models run $2,000 to $4,000 per ear, and premium models can exceed $6,000 per ear. Most people buy a pair (two hearing aids), so the total cost is usually double the per-ear price. The price includes the device itself, the fitting appointment, and adjustments during the trial period.
Medicare does not cover hearing aids, but some Medicare Advantage plans do — you have to check your specific plan. Veterans may be covered through the VA. Some state Medicaid programs cover hearing aids for children and adults, but coverage varies by state. Private insurance rarely covers them. A few employers offer hearing aid coverage as part of their health plan.
If you do not have coverage, ask your provider about payment plans. Many hearing aid companies offer financing options that let you pay over time. Some nonprofits and community health centers offer reduced-cost hearing aids or refurbished models. Your audiologist can tell you what options exist in your area.
Do I Need a Doctor's Referral to Get a Hearing Aid?
You do not need a referral, but you do need a hearing test first. You can get a hearing test from an audiologist (a specialist in hearing) or from your primary care doctor. Some hearing aid stores have audiologists on staff and can do the test in the same visit. If your doctor does the test, they will refer you to an audiologist or hearing aid provider for the fitting.
The hearing test measures how well you hear at different frequencies and volumes. It takes about 30 minutes and is painless. The results show your audiologist exactly what kind of hearing loss you have and how severe it is, which determines what type of hearing aid will work best for you and how it should be programmed.
If you have never had a hearing test, starting with your primary care doctor is reasonable because they can rule out treatable causes of hearing loss (like earwax buildup or an ear infection). If they find no medical cause, they will refer you to an audiologist.
What Happens During the Fitting Process?
The fitting usually takes place over several visits. At the first visit, your audiologist will review your hearing test results, discuss your lifestyle and what situations are hardest for you (like restaurants, family gatherings, or phone calls), and show you different hearing aid styles. You will try them on, and the audiologist will program them based on your hearing loss and your preferences.
You will take the hearing aids home for a trial period, usually 30 to 45 days. During this time, you wear them and get used to them. Your brain has to relearn how to process amplified sound, so the first few weeks often feel strange — voices may sound too loud, or you may notice background noise you had forgotten about. This is normal and usually improves as you adjust.
You will come back for follow-up visits so the audiologist can adjust the programming, answer questions, and make sure the fit is comfortable. Most people need two to four follow-up visits before they are satisfied. If the hearing aids are not working for you by the end of the trial period, you can return them for a refund.
What Maintenance Do Hearing Aids Need?
Hearing aids need daily cleaning because earwax and moisture build up on them. You wipe them with a dry cloth and use a small brush or wax pick (usually provided by your provider) to clear the speaker. If your hearing aids have rechargeable batteries, you place them in a charger at night. If they use disposable batteries, you change them every few days to a few weeks depending on the model and how much you use them.
You should store your hearing aids in a dry place when you are not wearing them — not in the bathroom where moisture is high. If they get wet, dry them thoroughly before using them again. Some people use a hearing aid dehumidifier overnight to remove moisture. Your audiologist will show you the cleaning routine and what products are safe to use.
You should also have your hearing aids checked by your provider once a year. They can clean the internal parts, test that they are working properly, and update the programming if your hearing has changed. If a hearing aid stops working, your provider can often repair it, though repairs may cost money if they are not covered under warranty.
What If I Lose a Hearing Aid or It Breaks?
Most hearing aid providers offer a loss and damage warranty that covers accidental damage and loss for a fee — usually $100 to $300 per incident. The warranty typically lasts two to three years and covers a certain number of replacements (often two). If you lose or damage a hearing aid outside the warranty period, you will have to pay the full price for a replacement, which is why the warranty is worth considering.
If your hearing aid breaks and is still under warranty, contact your provider. They can usually repair it within a few days to a week. If it cannot be repaired, they will replace it. If you lose a hearing aid, report it to your provider right away — they may be able to help you find it, and they can tell you what the replacement cost will be.
Some people buy a second pair of hearing aids as backup, especially if they rely heavily on them for work or social activities. This is expensive but means you have a pair to wear while the other is being repaired.
Frequently Asked Questions
Can I buy a hearing aid online without seeing an audiologist?
You can buy over-the-counter hearing aids online without a test or fitting, but they are not customized to your hearing loss. They amplify all sound equally, which works poorly if your hearing loss is worse at certain frequencies. A fitted hearing aid is programmed specifically for your hearing pattern, which is why it works better. Over-the-counter models are cheaper but less effective for most people with significant hearing loss.
How long does it take to get used to wearing a hearing aid?
Most people need two to four weeks to adjust to the feel of wearing a hearing aid and to get used to amplified sound. Your brain has to relearn how to process sound, and background noise that you had stopped noticing will suddenly be audible again. This adjustment period is normal. If after six weeks you still cannot adjust, talk to your audiologist about whether a different style or programming might work better.
Will a hearing aid make my hearing worse?
No. Hearing aids amplify sound but do not damage your hearing. Hearing loss is caused by damage to the inner ear, and wearing a hearing aid does not cause that damage. However, if you wear a hearing aid at very high volumes for long periods, you could damage your remaining hearing, so your audiologist will program it at a safe level.
Can I wear a hearing aid in just one ear?
Yes, if you have hearing loss in only one ear. However, if you have hearing loss in both ears, wearing two hearing aids usually works better because it helps your brain locate where sound is coming from and makes speech easier to understand in noisy places. Your audiologist will recommend what makes sense for your specific hearing loss.
What should I do if my hearing aid keeps falling out?
Tell your audiologist at your next visit. The fit may need adjustment, or you may need a different style. Some people use a retention cord or clip that attaches the hearing aid to your clothing so it does not fall and get lost. Your audiologist can show you options and help you find what works for your ear shape and lifestyle.
