Tip - Silence the phones

You're on a roll, you're recording your best piece of audio ever..... and then one of your phones in the room rings, throwing you completely off. Although it seems obvious, you would be surprised at how easy it is to ruin a recording by being thrown off due to the phone ringing.  Remember to turn off/silence/unplug your phones when recording. More recently this also applies to computer noises such as twitter/facebook alerts. If you hear the Microsoft Windows shutting down sound then you have probably lost your recording anyway! If you have any tips yourself, please do add them to the comments.
