For all the new bells and whistles packed into the new iPhone 3G S, we had no idea it featured an integrated high-frequency hearing test! No, we’re not kidding. Our iPhone 3G S has been testing our hearing acuity every time it plays a sound file, and yours probably is as well. Okay, we’re kind of kidding.
It would be great if the high-frequency tones being emitted after most system sounds (lock, unlock, new mail, etc.) were intended. But, as Phone Arena notes, it’s more likely a software problem that is “plaguing” many an iPhone 3G S out there. For the moment, there’s no fix, but that doesn’t mean Apple isn’t cooking up an update/patch post-haste!
If you’re interested in testing your iPhone 3G S for the high-frequency tone bug, just go to a quiet room and turn the phone off, or swipe to unlock (just make it play a system sound). If you hear a 15kHz tone buzzing immediately following the system sound, your iPhone 3G S is affected. If not, your iPhone 3GS is bug-free. That, or you’ve lost the ability to hear frequencies at and above 15kHz – which is unfortunately much more likely.
So, iPhone 3G S owners. Can you still hear tones at around 15,000 Hz?
