## What is Hearing Number?

How’s your hearing? Learn your Hearing Numbers—the softest sound you can hear in each ear—with an app created by the Johns Hopkins Bloomberg School of Public Health. Then use your Hearing Numbers to protect your hearing and hear better. Track your hearing to know how it changes over time and encourage others to know their hearing. Take charge of your hearing wellness! 

Hearing Numbers can be as low as -10 or as high as 100 decibels, or dB. The higher your Hearing Numbers are, the louder sounds will need to be for you to hear them, and the harder it will be to hear and communicate in noisy places.  

Requires headphones, a quiet space, and about 5 minutes to complete.
No advertising, in-app purchases, or product recommendations.
The app tests the noise level around you, measures your hearing levels at four frequencies in each ear, and provides your Hearing Numbers. 
Share the Hearing Number app and encourage your friends and family to learn their Hearing Numbers. 
Re-check your Hearing Numbers from time to time and review previous results to track how your hearing changes over time.

This app is created by the Johns Hopkins Bloomberg School of Public Health, seeking to empower people to know their hearing—millions at a time.

### 5/5 — Love newer version of the app

*2026-06-11*

I have been using older versions for years, great app, newer even better!

**Developer response:** Thank you for your feedback! Best regards, Hearing Number Team

### 1/5 — Headset Support

*2026-02-09*

You must have a supported headset or results purportedly may be inaccurate. Not going to buy a headset just for the test. I suppose the only way to find out is to download the app. Shame because I would have placed a greater degree of confidence in this test versus others available.

**Developer response:** Dear User, thank you for sharing your feedback. We are actively looking into adding support for more headphone models, but we are unable to provide a specific timeline at this time. Rest assured, our team is diligently working on this, and we appreciate your patience. Stay tuned for future updates! Best, Hearing Number Team

### 1/5 — Does not explain

*2026-01-09*

Terrible job at explaining what the number means. I had to ChatGPT it. Fails at the core mission.

**Developer response:** Thanks for your honest review. We appreciate you pointing this out. Best, Hearing Number Team

### 1/5 — Never recognized my headphones

*2026-01-09*

I don’t have Bluetooth headphones and even though I can effortlessly use my Bose headphones with my music and podcasts this app would not believe I was connected to headphones. Big miss.

**Developer response:** If the app does not recognize Bluetooth headphones, please follow these steps: 1) Reconnect headphones.
Go to Settings -> Bluetooth, then disconnect and reconnect your headphones. 2) Test headphones.
Play music or a video through a different app. Check if you can hear the sound through the headphones. 4) Check other connections.
Make sure your headphones aren’t connected to another device. Turn off Bluetooth on devices that might be connected to your headphones. 5) Restart the app.
Close the app completely and then reopen it to refresh the connection.
If you need more assistance, please contact us at support@hearingnumber.org.

### 4/5 — $350 headset not supported.

*2025-09-19, version 1.2.0*

It seemed to have worked well. Minus not supporting my headphones. I first tried some Beats but mine weren’t on the list, so I went to grab my Corsair Virtuoso Max and they also weren’t supported. It wants your mic turned on and detects you breathing as a loud noise. Could be accurate but it holds your headset against you.

### 5/5 — Super helpful app for understanding your hearing

*2025-05-10*

App worked great. Took about 4 min. First time I’ve taken a hearing test since I was in 2nd grade!!

**Developer response:** Thank you for your feedback and for selecting our app to support your well-being! Best regards, Hearing Number Team

### 1/5 — Couldn’t take test

*2025-02-23*

Unable to navigate beyond privacy page with iPhone 13 Pro and iOS 18.3.1.

**Developer response:** We deeply apologize for the inconvenience you have experienced with our product. We recommend trying to use a different network connection, switch to Cellular Data if you are currently using WLAN, or vice versa. If the issue persists, please reach out to us at support@hearingnumber.org for further bug investigation. Best regards, the Hearing Number Team
