Whether you’re experiencing hearing loss due to aging, genetics, damage, or some other reason, untreated hearing loss can lead to social isolation, depression, and a poor quality of life. That’s why it’s important to catch it early and start treatment as soon as possible. One easy way to keep tabs on your hearing is to take an online hearing test. These fast, convenient, and accessible evaluations can tell you if your hearing is considered typical or atypical. But they don’t replace a thorough diagnostic exam, so you should talk with an audiologist if an online hearing test suggests you have hearing loss.

Even though online hearing tests are free, you may want to be choosy about which ones you take. Some told our testers they had significant hearing loss, which isn’t true. Even though companies may offer the best hearing aids, you may not actually need them.

We know how important it is to catch hearing loss early, so you can treat it and continue living your vibrant and active life. To that end, we tried out more than 30 online hearing tests for accuracy and trustworthiness, narrowing it down to the four best online hearing tests and outlining their strengths and weaknesses in this review. Any online hearing test may give inaccurate results if you don’t sit in a quiet place and wear a good pair of headphones or earbuds, so we also spent some time outlining best practices for taking these tests. As with any health changes, we recommend visiting a hearing care provider if you are concerned about the accuracy of your results.

Our review

If you’re ready to talk to a hearing specialist about buying a hearing aid, you’ll appreciate how fast the Jabra Enhance team follows up. Within minutes of completing this online hearing screener, we received a phone call and email from a friendly and knowledgeable Jabra Enhance representative.

It’s not just the speedy response that impresses us but also the quality of care. Based on our experiences with the Jabra Enhance remote audiology team, we feel confident that this brand will take care of you without being pushy.

From our expert

“I would recommend sticking with screeners offered by audiologists or hearing-related professionals so you know follow-up care will be adequate.”—Kit Frank, audiologist at The Hearing Hub, Las Vegas

Twelve progressively larger circles indicate louder tones

Jabra Enhance online hearing test

How to take the hearing test

The Jabra Enhance online hearing screener tests each ear individually, starting with your right ear. You’ll see a row of progressively larger circles numbered one through 12. Click on the circle labeled one and listen for a tone through your right headphone. If you don’t hear anything, click the circle labeled two. Repeat this process until you hear the tone, even if it’s barely audible. You can go back down the scale if you want to double-check what you heard.

When you’re satisfied you’ve selected the lowest-numbered circle where you can hear the tone, click Save and Continue.

You’ll go through that process four times in each ear. At the end of the test, you’ll be asked to enter your name, email, and phone number so the Jabra Enhance team can follow up with you.

How to interpret the results

Each ear is given one of the following labels:

  • No impairment detected.
  • Impaired.
  • Significantly impaired.
  • Severely impaired.

You’ll also see a breakdown of each ear’s results in the high, mid, and low frequencies. Click View details under each section to learn which consonant or vowel sounds you may have difficulty hearing and which sound environments may be most challenging. We love how these results are specific and easy to understand.

What our testers say: “The Jabra Enhance test was one of the few that actually helped me understand how hearing loss affects everyday comprehension. Its directions were easy to follow, and it didn’t take long to complete. I appreciated the fast follow-up so I could talk about my results while they were still fresh in my mind.”

Our verdict

The Jabra Enhance online hearing test is the best option if you want a licensed audiologist to explain your results for free.

Our review

The Starkey online hearing test evaluates eight tones in each ear and includes a unique 10-question speech comprehension test—a rare combination that easily makes this the most comprehensive online hearing test. It’s fast, simple, and doesn’t require an email address. However, we wish this test displayed results as an audiogram (the written results of your hearing test) and did a better job of explaining the score.

From our expert

“A good online hearing test should include three main components: A questionnaire, pure-tone testing of at least four different frequencies in each ear, and some form of speech in noise testing.”—Lindsey Banks, an audiologist at DrHearingLoss.com

Starkey speech test

How to take the test

The Starkey hearing check starts with three yes-or-no questions about your hearing and some volume calibration. It then goes into the pure-tone test, which is a standard audiometry test for determining the lowest sounds a person can hear. Click the plus sign until you’re able to hear the tone—even if it’s very soft. Repeat this until all eight tones have been tested on both ears. Unfortunately, Starkey doesn’t label the frequencies as they’re tested, so you won’t know exactly which frequencies give you trouble.

Next, you’ll start the speech recognition test. There’s no way to repeat the word, so you’ll have to take your best guess. There will be light background noise to contend with too.

Sample Starkey online hearing test results page

How to interpret the results

Your results will be displayed on a scale from normal to severe. If you have normal hearing, you won’t see a breakdown of your results. If the test detected some impairment, you can scroll down to see which words you missed in the speech recognition test.

We wish Starkey provided a better explanation of the sounds that you might have trouble hearing. Displaying the user’s answer below the correct word would be a good start. Otherwise, if you’re looking for a one-word result from an in-depth screener, the Starkey test is a good option.

What our testers say: “I preferred the format of the Starkey speech test over some of the other online screeners. You get multiple choice options that all sound a little different, and the voice sounds natural—not overly enunciated. I felt I could trust these results.”

Our verdict

The Starkey online hearing test is the most comprehensive yet easy-to-use option because it screens for more tones and letter sounds than the competition.

Our review

The MDHearing pure-tone test is quick, simple, and gives results in easy-to-understand language with an audiogram. It doesn’t include speech comprehension testing, and you do have to provide an email address, but the detailed results make this an excellent hearing screener for people who are testing their hearing for the first or 10th time.

From our expert

“A standard hearing test measures your ability to hear sounds at varying frequencies (pitches). The softest sound you can hear is called your ‘hearing threshold’ and is charted on a graph called an audiogram.”—Lindsey Banks, audiologist at DrHearingLoss.com

Progressively larger bars indicating softer and louder sounds

MDHearing online hearing test

How to take the test

After entering your name and email address and confirming that you’re in a quiet room, you’ll be prompted to set your device’s volume to 100 percent. If there’s any chance you’ll get audible notifications through your device, now is the time to mute them if possible.

Next, you’ll confirm that the sounds meant for your left ear play for your left headphone. Then you’ll go right to the pure-tone test.

In the MDHearing test, the sounds play at a medium volume right away. If you can already hear the tone, press the minus symbol to find the lowest level you can still hear. If you can’t hear the tone, press the plus symbol until you can. Then press Save and Continue. Repeat this process until you reach the results page.

Don’t forget to turn down the volume on your device.

Color-coded audiogram showing normal hearing in both ears

Sample MDHearing results page

How to interpret the results

MDHearing displays your online hearing test results in three ways: on a scale from healthy to profound hearing loss, as an audiogram, and through a written description. We love that everything is color-coded so you can easily see the difference between your left and right ear and understand the severity (or lack thereof) of your hearing loss.

Click Read more under each frequency to learn about common sounds that fall into that range. We’d like to see MDHearing include the consonant and vowel sounds that correspond to each frequency too. Right now, the results page explains three letter sounds affected by high-frequency hearing loss, but that’s it.

If desired, you can also book a free 30-minute call with an MDHearing audiologist to get a personalized explanation of your results. On the results page, scroll up and click Book Now.

What our testers say: “I was impressed by how much information and education is available on the results page, especially since this is a pretty easy and fast test. Even though I had to share my email address, I didn’t get overwhelmed with marketing emails—for once!”

Our verdict

Because it visualizes your score in several ways and features simple explanations, the MDHearing online hearing test is a great choice for people who want easy-to-understand results.

Most precise pure-tone test

Features

  • Type of test: Pure-tone, loud sound tolerance.
  • Website or app: App.
  • Audiogram results: Yes.
  • Contact information required: Yes.
  • Standout feature: You have 96 decibel levels to choose from to find the quietest sound you can hear.

Our review

The SonicCloud Personalized Sound app is one-of-a-kind. It tests eight frequencies per ear and lets you scroll through 96 increments to find the lowest volume at which you can hear the tone. This level of precision is unmatched in any other pure-tone test we’ve seen online. We also like that the results are displayed as an audiogram with potentially troublesome consonant and vowel sounds clearly marked.

It’s worth taking this test if you feel like other online pure-tone tests are too basic. We wish SonicCloud included speech comprehension testing and a survey for a more well-rounded hearing screening, but you can always supplement the results of this test with another like Starkey or even Shoebox.

 Illustration of a man singing on the SonicCloud hearing test

The SonicCloud online hearing test lets you fine-tune your response.

How to take the test

First, download the SonicCloud Personalized Sound app from the Apple App store or Google Play. The first 30 days are free, and you don’t have to enter payment information to access the free trial. After that, SonicCloud costs $9.99 per month. Don’t take the test on the SonicCloud website—it tests five frequencies instead of eight and doesn’t include the fine-tuning feature.

A second app called SonicCloud Sound Check is a simplified hearing test that screens for five frequencies instead of eight. We recommend the SonicCloud Personalized Sound app for a more comprehensive hearing screener.

After creating an account, connecting your earphones, and answering a couple of pre-test questions, you’re ready to begin. Drag the icon on the right-hand side up the line until you can barely hear the tone. Then tap Fine Tune. You’ll see 10 increments. Drag the icon up and down until you find the lowest number at which you can hear the tones. Then click Next. Repeat this process with each frequency on both ears.

The second part of the test evaluates your tolerance for loud sounds. Slowly drag the icon up until you feel like the tone is uncomfortably loud. Then click Next and repeat with each frequency on both ears.

Sample SonicCloud results page.

How to interpret the results

SonicCloud displays your results as two audiograms—one for each ear. You can toggle between them by tapping the ear icons toward the top of the screen. The consonant and vowel sounds that you can hear well appear below the line. The sounds that are more difficult to hear appear above the line. Tap on each cluster of letters to see the labels.

You will also receive a percentage for each ear called a Hearing Score. No guidance is given about what these percentages actually mean, so we reached out to SonicCloud customer service to clarify.

From our expert

“The score received is a representation of the percentage of English phonemes (letter sounds) that a user heard.”—SonicCloud customer service representative

If you have hearing loss, the next prompts will guide you through setting up the SonicCloud service, which makes the test’s audio easier to hear based on your audiogram and other preferences. If you’re not interested in this, you can save and exit at any time by tapping the pause icon. You can also elect to receive a follow-up call from a hearing care professional.

You can retake the hearing assessment as many times as you wish, and SonicCloud stores each one so you can look at them later. You can also export the audiogram results to Apple Health.

What our testers say: “This is a really dynamic test with tons of fun visuals. It’s the longest hearing screener I’ve taken, though, so you really need to carve out 10 or 15 minutes of quiet time to focus on this test. I loved the professional-looking audiogram at the end, which SonicCloud explained in simple terms.”

Our verdict

Featuring single decibel increments on its pure-tone and sound tolerance tests, the SonicCloud app lets you give more precise answers compared to other online hearing screeners.

Other online hearing screeners to consider

Shoebox

Shoebox, the makers of the online hearing test used by Widex and Signia, among others. evaluates hearing through a seven-question survey, pure-tone testing, and a quick speech-in-noise test, but it’s not as comprehensive as other options. You could take this test to confirm the results of other online hearing screeners, but it’s not our first recommendation.

It tests four tones per ear—fewer than Starkey, MDHearing, and SonicCloud. The speech comprehension test simply asks you to increase the volume of a dictation until you can understand the words, which isn’t as precise as the Starkey test. Finally, you don’t get any meaningful results other than a basic description of your hearing (good, loss, or significant loss). 

If you want to take the Shoebox hearing test, go through the Widex website so you don’t have to share your contact information.

hear.com Clinic-in-a-Box®

The hear.com Clinic-in-a-Box is more of a telehealth test than an online hearing screener. hear.com mails several devices, and a hearing care professional teaches you how to use them through a video appointment. For example, you insert a tiny camera into your ear to check for earwax blockages and wear headphones that test bone conduction—two procedures that usually require visiting a hearing center. Pure-tone and speech comprehension testing is also part of the process.

Our tester using the hear.com Clinic-in-a-Box

If you’re interested in the Clinic-in-a-Box, you’ll complete a questionnaire online to log your symptoms and hearing health history. Then, an audiologist will call you to discuss the brand’s solutions. If you agree to buy the hearing aids (with a 45-day money-back guarantee), hear.com will send the Clinic-in-a-Box. At the end of the virtual hearing exam, the audiologist will remotely program your hearing aids based on your audiogram. 

Our testers thought the Clinic-in-the-Box teleaudiology appointment was comprehensive, but we also found it’s essential to leave everything in the box until instructed to remove devices because it’s easy to get the various cords mixed up. 

Online hearing tests to avoid

The “numbers” test

This format is used by Lexie Hearing, Beltone, and Best Buy. The test asks you to select the three numbers you hear spoken against some intense static. There are 23 number sets in total. There’s no way to repeat the numbers, and the instructions also tell you to guess if you didn’t hear a number, which seems imprecise. We also don’t like that it doesn’t screen each ear individually, and there’s no pure-tone test to supplement the results of this speech recognition test. 

Our testers were more likely to receive poor hearing scores through the Beltone version of this test, so it may be calibrated incorrectly.  

uHear app

Created by Unitron, the uHear app test was difficult to navigate because the screen didn’t adapt to the full size of our tester’s phone. The pure-tone test was frustrating to complete because a distracting icon moves around a circle and flashes red when you don’t hear a tone, which made our tester feel like they were doing something wrong. The speech-in-noise test is more of a volume tolerance test, as you have to choose a comfortable speech volume level instead of identifying specific words.

The uHear app gave our testers worse results than other online hearing tests, so we don’t feel comfortable recommending it. 

The Sonova test

Sonova developed an online hearing evaluation that can be taken in less than three minutes. It’s also used by companies like Phonak, the Ear Institute, United Healthcare, and Sennheiser. It provides a six-question survey to gauge your hearing health and a pure-tone test that screens for 2 kilohertz and 4 kilohertz in the right ear and 1 kilohertz and 6 kilohertz in the left ear. 

However, this test seems to only consider your survey responses. When we indicated that we had a lot of trouble hearing but intentionally chose the lowest volumes on the pure-tone test, it said we had poor hearing. When we answered all the questions as if our hearing was normal but chose loud volumes for the pure-tone test, the results said we had good hearing. 

The graph also shows results for frequencies that weren’t even tested (500 hertz and 8 kilohertz), which is another reason we don’t trust this test. 

What is an online hearing test?

An online hearing test is a convenient way to check for changes in your hearing from your home environment. We like to think of these tests as the first step in caring for your hearing, with the results determining whether you need to pursue treatment or require a more comprehensive, in-person exam. Using headphones or earbuds, the tests prompt you to listen to a series of clips to measure sensitivity to different pitches. 

Some services will test more comprehensively than others, providing detailed results and ideas for follow-up care, while others are more basic, lasting only a few minutes. In general, all online hearing tests will present your results as a comparison against the hearing and pitch sensitivity norm.  It is important to know that many online hearing tests may benefit from your test results, encouraging you to purchase hearing aids from the site offering the test. This is a good reason to research online hearing tests and proceed cautiously after receiving your results.

Online vs. in-person hearing tests

While some online tests are more comprehensive than others, an in-person hearing test will always offer the clearest picture of your hearing health. Online tests are only equipped to test your sensitivity to sounds as they enter your hearing canal through earbuds or headphones, called air conduction testing. This test can determine if hearing loss exists, but bone conduction testing is necessary to determine where in the hearing system the problem exists. Depending on the root of the hearing loss, it may be medically treatable or managed with a hearing aid. Even so, that doesn’t mean you shouldn’t turn to an online hearing test, as these tests are a good way to detect early hearing loss before taking further steps for evaluation and treatment.

Who should take an online hearing test

An online hearing testing is a good choice for anyone experiencing mild hearing loss symptoms or unsure if your hearing has changed. It also may serve as a good way to establish a baseline for hearing health to watch for changes in the future. 

Some signs of hearing loss include asking people to repeat themselves or needing them to slow down or speak up, requiring a louder volume of music and television shows, and difficulty understanding conversation with background noise. Some people with early hearing loss will also feel sounds are muffled or that the consonants in words have become harder to hear.

Who should not use an online hearing test

Online hearing tests are not for everyone, and many people who take these tests will find they need to follow up with a doctor to get a more comprehensive understanding of their hearing health.

Anyone with symptoms of more severe hearing loss should see an audiologist instead of taking an online test. Additionally, sudden changes to hearing or ear health require immediate medical care. These include a sudden loss of hearing in one or both ears, tinnitus or ringing in the ears, ear pain, excess wax, or blood and pus in the ear.

Pros and cons of online hearing tests

What we like about online hearing tests

Online hearing tests are:

  • Free.
  • Fast.
  • Easy to take.
  • Accessible.
  • An option for people not ready to see an audiologist.

Due to the invisible nature of hearing loss and the gradual onset of change, hearing loss is not typically noticed by the individual. The reality is that hearing loss goes undetected for an average of seven years

From our tester

“Sometimes I ask my partner to repeat himself because I don’t catch what he says. He thought I should get my hearing checked, but I didn’t feel like it was serious enough to go through all the rigamarole of making an appointment. What if he’s just mumbling? An online hearing test was the most convenient way to figure out my next steps.”

What we don’t like about online hearing tests

Online hearing tests have several limitations:

  • Results can be affected by headphone quality and background noise.
  • Many do not offer speech comprehension testing. 
  • Many do not offer sound tolerance testing.
  • Some do not test each ear individually.
  • Earwax blockages can’t be evaluated.
  • Can’t perform diagnostic tests, such as tympanometry (tests eardrum movement), bone conduction (tests inner ear function by vibrating bones), acoustic reflex (evaluates inner ear muscles), or otoacoustic emissions (records sounds produced by the inner ear).
  • Results may not be standardized and can be confusing to interpret.

Because of these restrictions, Frank, the audiologist in Las Vegas, says online hearing tests are better described as online hearing screeners or precursors to a full-fledged hearing exam. If an online test says your hearing is normal, you probably have nothing to worry about. But if the results suggest impaired hearing, experts recommend an in-person exam to get to the root cause and find the best solution. 

There are so many options for hearing ‘tests’ online, but they should really be viewed as screenings where you are referred to professional help if you don’t pass.

Kit Frank, audiologist at The Hearing Hub, Las Vegas

Many online hearing screeners are offered by hearing aid companies who will naturally steer you toward their products and services. But hearing aids may not be the right answer for you. Hearing loss treatments also include antibiotics to treat an infection, ear tubes to allow fluid to drain from behind the eardrum, earwax removal, and tumor removal. 

Online hearing test costs

All of the online hearing tests we’ve listed above are free except for the Hear.com Clinic-in-a-Box®, which is available with the purchase of Hear.com hearing aids and backed by a 45-day money-back guarantee. 

The SonicCloud hearing test can be taken for free within 30 days of creating your account. After that, the SonicCloud app costs $9.99 per month.

Before we tested online hearing screeners, we asked two audiologists to help us develop testing criteria. According to Lindsey Banks, an audiologist at DrHearingLoss.com, and Kit Frank, an audiologist at The Hearing Hub in Las Vegas, online hearing tests should do the following:

  • Gather information about the patient’s hearing history and current hearing challenges.
  • Screen each ear separately.
  • Measure room noise.
  • Test at least four frequencies.
  • Evaluate speech comprehension in noisy and quiet environments.
  • Give clear guidance on when to seek professional care. 

A good online hearing test will have strict referral criteria to send you for in-person testing if the results are abnormal in any way. An added bonus for an online test is if your results are reviewed by a professional.

Kit Frank, audiologist at The Hearing Hub, Las Vegas

We added a few criteria of our own:

  • Can you get results without providing personal information?
  • Are the results clearly explained?
  • Do the results agree with other online hearing screeners taken by the individual, or are they significantly different?

Next, we turned to Google to compile a list of the online hearing tests most likely found by searchers. We also included hearing tests from popular prescription and over-the-counter hearing aid companies and asked audiologists to name any with good reputations. Our final list contained more than 30 online hearing tests. 

We then took each online hearing test. The first time we completed each test, we tried to be as accurate as possible with our responses to identify any skewed results. 

From our tester

“Most of the hearing tests I took said I had normal hearing and that my left ear hears slightly worse than my right ear, which is accurate based on my latest visit to the ear, nose, and throat doctor. But the Beltone hearing test said I had ‘impaired to severe’ hearing loss, so I wouldn’t trust that one.”

If the test said we had typical hearing, we took it again with random answers to see what guidance would be given to people with hearing loss. 

We didn’t find a free online hearing screener that meets all the criteria set by Banks and Frank. Speech comprehension testing is relatively rare, as are background noise measurements. We also found that many online hearing tests use the same format, which narrows the field. Widex, Signia, Humana, and HearUSA all use a test developed by Shoebox, for example.

From our tester

“The HearUSA test is exactly the same as the Widex test except you have to share your contact information.”

Our top choices reflect the most thorough, trustworthy, and user-friendly online hearing tests we could find. 

Our final verdict

We think the Jabra Enhance, Starkey, MDHearing, and SonicCloud online hearing tests are the best options available, and each one brings something a little different to the table. Because they’re free and fast, it doesn’t hurt to try all four. On the other hand, we found flaws in the “numbers,” uHear, and Sonova tests, so we recommend skipping those to avoid confusion.

Free online hearing tests can help you track changes in your hearing, but they aren’t foolproof. Schedule a doctor appointment if you believe your hearing is getting worse, even if an online hearing screener shows no change. Audiologists can conduct additional tests to make sure your ears have healthy bones, nerves, and soft tissues.

Frequently asked questions

Yes, all you need is a good internet connection, a quiet place, and a pair of headphones to test your hearing online.

Yes, you can take an online hearing test with your phone. Just visit the website through your favorite browser or download the app, if available.

Online hearing tests might say your hearing is worse than it actually is because the quality of your headphones and the amount of background noise can make it more difficult to hear low-decibel tones. Plus, they aren’t diagnostic. A comprehensive hearing test performed by a licensed audiologist will always give the most thorough and accurate results, but an online hearing screener can give you a sense of your current hearing levels and help you track changes over time.

It depends on the format of the hearing test. We completed some in 90 seconds and others in 15 minutes. On average, an online hearing test takes about five minutes.

No, online hearing tests do not screen for tinnitus. That said, some brands like Starkey offer a separate tinnitus screener that asks you to rate how tinnitus impacts your life.
