Frequently asked questions

Hearing Test

Yes. We take into account the expected delays of interacting with your mobile device.

Our test is designed to work in a quiet environment. If the test is taken in a noisy environment the results may be inaccurate. For accurate results, we suggest waiting until you can find a quiet place before taking the test.

This is called a contralateral masker and is to be expected. It is used when testing hearing. The contralateral masking noise (in the opposite ear) appears when the pure-tone reaches a certain volume. This masker prevents ‘cross talk’, a phenomenon in which the ear not being tested picks up the sound for the ear that is being tested.

Every headphone model has a different tuning, potentially affecting the results of your hearing test. For supported headphones we take these differences into account when processing your data, ensuring that the test results are consistent and accurate independent of the specific headphone characteristics.

The Mimi App currently supports the following headphones: Apple EarPods, Apple AirPods (1st, 2nd, and 3rd generations), Apple AirPods Pro (1st and 2nd generations), Apple AirPods Max, Powerbeats Pro, and Beats Fit Pro.

You can use the model number of your AirPods to find out which generation of AirPods you have. 

  1. Go to Settings > Bluetooth. Alternatively, you can go to Settings > [your AirPods].
  2. Find your AirPods in the list (for example, “John’s AirPods”).
  3. Tap the More Info symbol button next to your AirPods.

Now that you have the model number, you can use it to learn which AirPods you have. Read the full overview on the Apple website: Identify your AirPods

If your headphones aren’t on our supported list, it means we haven’t yet gathered the necessary data to include them in the test. You can still go ahead with the test, but please be aware that the results might not be as accurate. Offering support for additional headphones takes time, but we’re actively working to extend the list in the future.

Accuracy & Reliability

Under ideal test conditions and when used as intended, the tests provide accurate results. Our tests have been built and tested by both scientists and audiologists.

The Mimi Hearing Test App offers a Pure Tone Threshold (PTT) test – the Pure Tone Threshold (PTT) test is a type of hearing test that uses an automated procedure modeled after the Békésy tracking method. This makes it especially suitable for app-based mobile hearing tests. Originally, it was developed to automatically determine how well you can hear sounds of varying pitches through air-conduction. The accuracy of the PTT test has been confirmed through accuracy studies conducted in our lab and with various partners. These studies compare the PTT test to a recognized standard under the same conditions. We have also conducted studies to verify the reliability of the test.

Several factors can influence the accuracy of your hearing test results, such as your overall well-being, ambient sounds, headphone model, and time of day. Background noises may make it harder to perceive test signals near your hearing threshold, which may distort your test results. Also, it’s essential to avoid loud noise exposure before taking the test, as it can affect the outcome. Loud noise can cause auditory fatigue, where the ears become temporarily unresponsive due to overstimulation. Therefore, it’s crucial to test under quiet conditions, without any recent extreme exposures that might temporarily impact your hearing ability.

For the most reliable results, follow these guidelines:

  1. Use supported headphones.
  2. Take the test in a quiet environment.
  3. Turn off any sound enhancements on your device, including headphone safety functionality, headphone accommodations and  audio balance.
  4. Avoid recent exposure to loud sounds.
  5. Check that your headphones are tightly and symmetrically fit to your ears.
  6. Ensure your device has sufficient battery power, is plugged in, and that you avoid interruptions.
  7. Try to take the test under similar conditions each time to consistently monitor your hearing.

Some people have asymmetric hearing, meaning the ear’s hearing abilities differ. In these cases, the better ear can partly compensate for the other. Your hearing grade is defined by your better performing ear.

Yes, you can still complete the test assuming that the tinnitus occurs within narrow bands of frequencies. Note, however, that in these ranges, the threshold can not be accurately determined with our test, because the Tinnitus sound is masking the faint test signal. The test results in other frequency ranges should not be affected, though.

If you have any concerns about your hearing, please follow up with a hearing healthcare professional. Mimi does not supersede or replace a decisive diagnosis by a physician, does not allow direct diagnosis and is not intended to be used for monitoring, treatment or alleviation of any disease or disability.
