iPad 2 microphones: 3G (top) vs. Wi-Fi (bottom)

iLounge reports that it has discovered differences in the quality of sound captured by the microphones on various Wi-Fi and 3G-capable models of the iPad 2, with the Wi-Fi-only models demonstrating the best sound quality. The differences primarily seem to stem from the fact that the microphone opening in the center of the top edge of the device is on an aluminum surface in Wi-Fi iPads and in black plastic on 3G models, although even the GSM and CDMA models behave slightly differently.Perhaps due to this change in materials, the Wi-Fi model offers markedly cleaner audio than that of the 3G, which sounds slightly muffled and echo-prone as a result. Curiously, we found the GSM 3G model's audio to be slightly preferable to that of the CDMA model, which seemed to suffer the issues more severely.According to the report, the differences are most pronounced when the iPad is held facing the user, as would typically the case when using FaceTime or other video-based apps.

The microphone has been located next to the headphone jack on the top edge of the first-generation iPad, but Apple presumably centered the microphone in the iPad 2 in hopes of doing a better job of picking up sound when used with FaceTime and other apps designed to be used in a forward-facing portrait orientation. It appears, however, that the acoustical qualities of the black plastic strip along the top edge used to house the antenna in 3G-capable models results in lower performance compared to Wi-Fi models with the microphone surrounded by aluminum.

With devices this complex, I would guess there's a fault somewhere.

I think the biggest fault is Apple not doing any real market user testing because they are scared of their secret new devices leaking out before Steve Jobs can announce it himself.

You can only find so many faults in something when you are so intimately close to it.

another example of design, over COMMON SENSE function -

It's a microphone - don't you think it belongs facing the front? One may work better than the other, but none will works as well as they should if they'd been placed were they belong.

Same problem with speaker location. :(

I would really like to know how the iPad 1 compares with these.

The iLounge report also said that the sound quality of the GSM iPad was better than that of the CDMA iPad. :confused:

Any way to confirm this?

Hey guys, can't you test this and post some real-life audio from your tests?
I'd be interested to hear de difference between the original iPad and the three iPad 2 models.

I'm in Canada and I need to confirm my choice before march 25th ;)

WiFi model is > 3G

Really glad I bought the WiFi version, and 4GB data pro iPhone tethering ftw.

Is the difference like "OMG, this sounds like crap" or more like "Fascinating, my sensitive acoustical diagnostic equipment detected a discrepancy in fidelity that just might be perceptible by human ears?"

Give me a break.

lol'd.

I'm getting the WiFi version anyway, not once did I put a sim card into my 3G 1st Gen.

My dog was complaining that the highest range confused him.

There was no high pitch discernible difference between "Good boy and bad dog"!

yea, where would you put the microphone and speaker(s) in the front? right next to the camera so it looks more like a giant iPhone4?
