Enabling Sound Isolation on iPhone after iOS 16.4 Update for Better Voice Calls

Apple recently released a new iOS 16.4 version update for iPhone users that brings a bunch of new features and security to the device. You have a version that is compatible with several iPhone models, but one of the most useful features released with the update is the noise isolation technology.

Apple claims that the sound isolation technology helps eliminate background noise during a call, resulting in clearer sound quality.

Apple has offered this feature for FaceTime calls since last year, and now all iPhone calls also support the technology. Now that the iOS 16.4 update is out, we got to experience the new feature and see if it has any effect on your regular voice calls on iPhone.

Apple iPhone Sound Isolation Feature for Calls: Does it Work?

First, how to get the noise isolation feature working on iPhone. It goes without saying that you need to install the new iOS 16.4 update (if compatible) and after that you will see a new option in Control Center. To enable it for calls, follow these steps:

– Make a voice call from iPhone and drag the control center from the upper right corner

– Click on the microphone icon to see the drop-down menu

– Select normal, soundproof and wide spectrum mode

It’s interesting that Apple has made the feature only available during a call. There is no possibility to adjust modes in the main settings of the device. Standard mode provides basic voice quality for calls, and wide spectrum is not currently available. But what about soundproofing, does it make a difference?

During our brief use of the function, we noticed some change, but only minor. It is possible that the performance of the feature is directly related to the strength of the network in your area, since you are answering a standard voice call. It’s also possible that Apple will continue to improve the user experience with future iOS versions.
