Apple may have dropped built-in noise cancellation on the iPhone 13

9to5Mac has reported that Apple may have removed the noise cancellation feature from the 13 series. The feature reduces ambient noise on phone calls when you hold the receiver to your ear.
One of 9to5Mac's readers was told by Apple support that phone noise cancellation isn't available on the 13 models. The support team confirmed that the feature is not supported when the reader asked for clarification.

Readers noticed that the noise cancellation page on the accessibility page was no longer available after the phone went on sale. The feature is still available on the past models of the device, but not on the new one.
"Noise Cancellation" uses an Apple camera microphone to detect and remove noise around you, so you can hear the other person on a phone or call, which can be useful for the hard of hearing. If you don't have Apple's noise-cancelling earphones, the issue only applies. It doesn't affect what other people hear, and Apple introduced the Voice Isolation feature with the new version of the software.
Apple has not officially confirmed that the feature has been permanently removed from the devices, but only indirectly from Apple Support. Engadget reached out to Apple for further clarification.
