The voice isolation feature of iOS 16.4 is a great feature, which has been introduced recently. With the help of this feature, background noise can be completely removed during the call.
To set this, you have to call someone from the call app. Now you have to pull down the Control Center from the right corner of the display.
Now tap on the mic mode button and open the mic mode setting. Here you will get the voice isolation option. Activate it. After this, the background noise from the call will be reduced considerably.
