As of 2022, we estimate that over 45 million Americans have some form of hearing loss, according to most hearing health experts—that’s approximately 1 in 6 adults!  And according to the World Health Organization (WHO), over 1 billion people aged 35 and younger are in danger of hearing loss due to prolonged and excessive exposure to loud music and other recreational sounds.* Unaddressed hearing loss can increase the risk of cognitive decline, dementia, falls, cardiovascular disease, social isolation, depression, and anxiety, but only 25% of those who could benefit from a hearing aid have ever used them.

Sound Match is a proprietary technology created to unlock the power of our self-fitting, over-the-counter hearing aids (Eargo SE, Eargo 5, Eargo 6, and Eargo 7).  In short, that means that you use Sound Match to self-adjust them to meet your unique hearing needs with no traditional in-office clinic visits needed to fit or adjust your hearing aids.

Sound Match requires the use of a smartphone and the Eargo mobile app for either 

 and takes about 15 minutes to complete, in-ear. You insert Eargo SE, Eargo 5, Eargo 6, or Eargo 7 hearing aids into your ear and you’ll hear sounds presented through the left and right devices at different loudness and pitch levels. If you hear the sound you’ll tap “Yes”, and if you do not hear it, you’ll tap “No”. You'll even have the option to tap “Replay” to try again. Pretty easy, right?

When you’ve completed the process, Sound Match will use your results to personalize your Eargo devices to your unique hearing profile. (If you prefer to work with a hearing professional, our team is available to guide you to show you how you can create custom audio profiles based upon your personal hearing preferences.) 

To update your devices with the results of your Sound Match profile, you’ll put them inside the charger. If you decide not to apply the Sound Match results, they will be discarded and your Eargo devices will remain with the programs that are already set. For devices without previously applied Sound Match results, these will be Preset Programs 1, 2, 3, & 4 (the factory default settings).

Amplification, especially for speech, increases as you go from Preset Program 1 to Preset Program 4. You can apply Sound Tuning on these programs for further changes to volume, treble, and bass. You may also select one of these presets as a favorite for each ear, and then add environmental programs (e.g. Restaurant and Phone). These environmental programs will use your selected Favorite Preset as their baseline. For the best and most personalized listening experience, we do recommend completing Sound Match, because it’s like tailoring an already well-fitting suit.

After Sound Match has been done, your hearing devices will have a “Normal” program—this is used as your everyday baseline. When you choose to add any other listening environments you would like to include inside your devices, such as “Restaurant” or “Phone,” they’ll be created using information from the Normal Program. This allows your listening experience to be optimized and personalized for each ear, no matter which environmental programs you choose to use.
