hey guys it's Brandon minimun from pocketnow.com right now we are recording a phone call through Skype we're going to test the noise cancellation on the iPhone 4 the iPhone 4 has two microphones one located on the bottom of the phone and one on the top of the phone to provide noise cancellation the only other smartphones I know of that can do this is the Google Nexus One so I'm going to test the noise cancellation with three scenarios one with sort of a gentle hum in the background in front of an air conditioner number two in front of a fan to kind of simulate being outside on a very windy day number three playing loud rock music kind of as if you are at a rock concert or a bar stadium or just somewhere where there's a tremendous amount of background noise so right now I am walking up to the air conditioner and I'm standing in front of the air conditioner it's kind of a gentle not terribly loud kind of a beefy sound so hopefully this is coming through alright what usually happens on the iPhone for noise cancellation is that it starts out kind of loud but then the software works and then it becomes quiet okay that was test number one I'm walking over to the fan to simulate being outside on a windy day you're probably not going to hear me because it takes for the iPhone to cut down the noise I'm going to jack up some loud music sort of as if we were at a rock concert so scream aloud so loud that I hear myself talk so if your knees off and the noise cancellation during my very good job cutting down the background really wow that was loud so that's it for the test on the noise cancellation of the iPhone 4 hopefully it worked please leave a comment below the video and let me know is it did work that's it for now
