Sounds like this aren’t supposed to happen. Since I made this recording, I’ve heard more sounds like this happening during all kinds of functions: even just switching between apps. I closed all the apps sitting in the “multitasking” bar at the bottom, and it’s still happening.
If anyone is experiencing this or knows a fix, let me know. If it continues, might be worth a trip to the Genius Bar. I don’t like it, I tell you!

Dude, some people pay *extra* for doodads that make those kinds of noises. It’s a *feature*.
It’s also an issue with the audio subsystem – my laptop used to do something similar due to one or another bug or evil application. I’ll go out on a limb & guess [warning: fake technical-sounding but actually highly nontechnical & vague language follows] that one or the other of yr apps has opened a hook to the part of Core Audio where it mixes audio from multiple apps, and has then puked & died, and somehow that’s causing audio from other apps to feed back strangely.
So a hard shutdown/restart will probably fix the problem until you use whatever the bad-actor app is, at which point it will start happening again.
I have pretty much all sound effects turned off on my iPhone, so for all I know it might be an app I use frequently as well, but I’d never know it.

Have you tried just shutting it down and restarting? if not, hold down the button on the top right of the phone for a few seconds, then slide to power off. Wait a few more seconds and repeat to power on. You will see an Apple logo.
If that doesn’t do anything, try going into Settings and hit “Reset All Settings”. This will reset everything to factory settings, but it should leave your Apps, Contacts, Network Settings and other content alone. Just be sure you DO NOT hit “Erase all Content and Settings”.
