The Apple Watch's noise detection feature is surprisingly very accurate

What you need to know

• A Reddit user tested out the Apple Watch's noise detection feature.
• He tested it against the Extech sound meter, a professional device to determine noise levels.
• The results were strikingly similar.

One of the new features arriving to the Apple Watch via the watchOS 6 update is the noise detection feature that can measure the decimal level of noise around you. While the feature very useful, it was fair to wonder how accurate the feature could be.

The answer is that it's surprisingly accurate.

First spotted by 9to5Mac, a Reddit user decided to test the accuracy of the Apple Watch against a calibrated sound meter from his job and the results were surprising to say the least. With a lot of noise in the background, the Apple Watch detected 88 dB of noise. The Extech sound meter, meanwhile, detected 88.9dB of noise.

The accuracy level is quite impressive. Technology has advanced at such a rapid pace, but even so, it's still impressive to see the Apple Watch produce noise level detection results at the same level of a device created to do just that.

The noise detection feature is now available for the Apple Watch Series 4 and Series 5 with watchOS 6.
