How to improve the audio quality of calls on iPhone

We've all undoubtedly been in a situation where we've had to take a call while there was lots of background noise going on around us. This can make it hard for the person on the other end to distinguish what we're saying. Luckily, iOS has some options that can help us improve call quality through noise cancellation as long as you're running iOS 7 or later. Here's how to enable the option:

Note: This may not be available for all models of iPhone. From what we're seeing and hearing, it appears to be available for the iPhone 5 and newer.

  1. Launch the Settings app from the Home screen of your iPhone.
  2. Now tap on General.
  3. Tap on Accessibility.
  4. Scroll down and under the Hearing section, enable the option for Phone Noise Cancellation.

That's it. While this isn't fool proof, it can help to reduce as much noise as possible when you're in a loud environment. This should help your caller be able to hear you better.
