Apple iPhone 4 Noise Cancellation Comparison
Loading...
Uploaded by almostzero on Mar 3, 2011
A friend of mine just recently decided to leave his Blackberry Torch for an Apple iPhone 4 from AT&T. He was curious about the phone call quality, in particular, the noise canceling functions of the iPhone 4 when speaking in a noisy area. I had him call me twice from the same location and leave me a voice message. The video and audio you see here are from both calls as captured direct from my phone. The first call was from a typical cell phone, the second from his Apple iPhone 4. Watch in HD for best audio quality!
Which did you think sounded better?

Hi, which software did you use to generate the synthetic female voice? It sounds really nice, thank you!

@rgisassi just cover the secondary mic (the little hole near the headphone jack) with you finger. In theory this should work.

@rgisassi @rgisassi The iphone 4 has more than one mic. One is there to talk into, and the other is there to suppress noise. The one you talk into is at the bottom of the phone, and the other one that suppresses the noise is by the headphone jack (it looks like a tiny hole, but it's a mic that can be used for speakerphone and VOIP, as well as noise suppression). It stands to reason that if you cover this mic up, it would have less background noise to suppress.

The other day a friend of mine called on his iPhone 4, and it took me two minutes before I figured out whom I was talking to. (The fact that I was talking on a samsung phone probably have something to do with that...)

Wow.

@prosserd Then you just copied me because you used the internet.

You got that backwards. Apple had an agreement in place with Audience long before Google became interested.

The choice is pretty obvious...The I-Phone

Can you turn the voice cancellation on and off? Sometimes, I want the other caller to hear my background.

@rgisassi: Excellent question. You cannot turn off the built in noise cancellation for the handset microphones. If you are using a bluetooth headset, it will not have any noise cancellation. I have not researched it, but the built in speakerphone may not use noise cancellation either.
