With the release of iOS 18.1, Apple introduced a clinical-grade hearing health ecosystem that transforms AirPods Pro 2 into an FDA-authorized over-the-counter (OTC) hearing aid. Designed for adults with perceived mild-to-moderate hearing loss, the system allows users to conduct a scientific, pure-tone audiometry test directly on their iPhone and automatically apply a personalized audio amplification profile across calls, media, and real-world conversations.
The Clinical Architecture of Apple’s Hearing Health Features
The Apple Hearing Test utilizes standard pure-tone audiometry methodology—the same diagnostic technique practiced by clinical audiologists. During the 5-minute evaluation, the iPhone transmits calibrated tones at varying frequencies (ranging from 250 Hz to 8 kHz) and diminishing decibel levels across individual ears.
The resulting data compiles into a personalized audiogram stored securely within the Apple Health app. The Hearing Aid feature uses this audiogram to dynamically boost conversational frequencies, adjust high-frequency consonants, and preserve spatial sound balance without artificial distortions.
Prerequisites for Testing and Hearing Aid Activation
To access the Hearing Test and Hearing Aid features, verify that your hardware and software meet the requisite standards:
| Component | Requirement |
|---|---|
| Earbuds | AirPods Pro 2 (with either Lightning or USB-C charging case) running firmware version 7B19 or later |
| Smartphone | iPhone running iOS 18.1 or later |
| Environment | A quiet indoor room with minimal background noise (under 45 dB ambient sound) |
| Age Restriction | The feature is medically validated and authorized for users aged 18 and older |
Step-by-Step Guide to Taking the Hearing Test
Follow these steps to conduct the diagnostic assessment in a quiet room:
1. Preparing the Ear Tip Fit
- Insert both AirPods Pro 2 firmly into your ears.
- Open Settings on your iPhone and tap your AirPods name near the top of the menu.
- Scroll down to Ear Tip Fit Test and tap Continue. Ensure you receive a “Good Seal” result in both ears before testing; an inadequate acoustic seal invalidates pure-tone results.
2. Initiating the Test
- In the AirPods settings menu, scroll down to the Hearing Health section.
- Tap Take a Hearing Test.
- Review the introductory health disclosures and confirm you have had no cold or ear congestion within the past 24 hours.
- Tap Get Started. The iPhone measures ambient noise levels; if the room is too loud, the screen prompts you to find a quieter space.
3. Performing the Pure-Tone Assessment
- The test evaluates one ear at a time, beginning with the left ear.
- A sequence of rhythmic pulses plays across various audio pitches.
- Tap the screen as soon as you detect a tone, even if the sound is faint. Release when the tone ceases.
- Repeat the procedure as the test transitions to your right ear.
Understanding Your Audiogram Results
Upon completion, the Health app displays your Hearing Level (dBHL) score for each ear:
- Up to 25 dBHL (Little to No Loss): Hearing falls within normal thresholds. Hearing Aid mode is unnecessary, but you can enable Media Accommodations to subtly refine music and podcast clarity.
- 26 to 40 dBHL (Mild Loss): Difficulty perceiving soft whispers or speech in noisy cafes. Hearing Aid mode is recommended.
- 41 to 60 dBHL (Moderate Loss): Difficulty following normal conversation without visual cues. Hearing Aid mode provides noticeable conversational amplification.
- 61 dBHL and Above (Severe to Profound Loss): Beyond the OTC parameters; the Health app recommends consulting an audiologist or ENT specialist.
Configuring and Customising Hearing Aid Mode
If your test results indicate mild-to-moderate loss, iOS immediately prompts you to enable Hearing Aid mode:
- Tap Set Up Hearing Aid from the results summary screen.
- Confirm that you wish to activate personalized amplification.
- Customise the acoustic balance by navigating to Control Centre, pressing and holding the Volume Slider, and tapping Hearing.
- From the Hearing control panel, you can adjust:
- Amplification: Adjusts master volume boost for ambient surroundings.
- Balance: Shifts bias between left and right ears.
- Tone: Modulates high-frequency brightness versus low-frequency warmth.
- Conversation Boost: Focuses microphone pickup beams directly on the person speaking directly in front of you during crowded dining or meeting environments.
