In watchOS 6, Apple added a hearing health feature to Apple Watch. The tool sends an alert when the noise around you reaches levels that could negatively impact your hearing. Here's how to use it.

Setting the noise tool in watchOS 6 on iPhone

The hearing health feature is automatically turned on in watchOS 6. However, you can turn it off and make adjustments using the Watch app on iPhone.

  1. Tap on the Watch app on your iPhone.
  2. Select the My Watch tab.
  3. Scroll down and tap Noise.

  1. Tap the toggle to turn off Environmental Sound Measurements.
  2. Tap Noise Thresold to make a change.
  3. Change the thresold from the list of choices, as applicable.

By default, the Apple Watch is set to alert you when the sound reaches 90 decibels. The World Health Organization says that people shouldn't experience this sound level for more than 30 minutes per day or else risk having hearing loss. You can adjust this number to 80, 85, 95, and 100 decibels. You can also turn the noise threshold off.

Each time your Apple Watch detects noises exceeding the threshold, you'll receive an alert. The watch doesn't record or save sounds to measure these levels.

Check your noise level in real time

To see what the current noise level is around you:

  1. On Apple Watch, tap the Digital Crown once to enter the Home screen.
  2. Tap the yellow and black Noise icon.
  3. Review the current noise level.

  1. Scroll down to read about the current noise level.
  2. Tap Learn More to see information on each level.

Apple breaks down noise into two primary levels: OK and Loud. From there, it breaks down noise levels even further by decimal ranges and the effects of each. For example, at a level of 90 to 95 dB, exposure for just 30 minutes a day, could cause temporary hearing loss. Meanwhile, at a level between 95 and 100 dB you could temporarily have hearing loss after only 10 minutes.

  • The app is not on my Series3 with watchOS 6. Does the Series3 not support this feature?
    Or is it not available in Europe (where I am)?
  • Ah - found the hint: https://support.apple.com/en-us/HT209593
    No Series3 Support :-(
  • Does using this feature often, or set it as complication, consume battery than normal?
