A related question: Is TV and movie dubbing 'bad' for us, or does it hurt our 'McGurkian' sensitivities to how visual and auditory cues should agree?
Read about the pros and cons of dubbing, and how Germany became a dubbing country. Skim this only if you have time. Although Germans generally understand and speak English very well, most of their TV shows and movies are dubbed from the original language into German. You certainly have experience watching an English language movie or TV show dubbed into Mandarin, and feeling the mismatch between lip movements and the sounds you're hearing, not to mention bad translations.
Bad lip synchronization of actors trying to mouth the lines of a recording in their own language can be irritating in a similar way. Some of you may choose to switch to subtitles and listen to the English, if your TV allows you to do so. How much do you feel the mismatch between sound and lip movements in this clip?

Another corollary of the McGurk effect is that we can make anybody appear to be saying — or singing — anything we want them to, if we match the words with carefully selected bits from video footage. How convincing do you find this? Your brain is integrating the information from the video quickly enough that it changes the phoneme you perceive in real time. Scientists have found that your brain can use this kind of real-time feedback with the information you hear so quickly that it can change the sounds coming out of your mouth.
They would make this change so quickly that they would hear the word they had been trying to say in their headphones. They would try to say bed, hear bad, change what they are saying to bid, and then hear bed through the headphones. Our brains are integrating this information so quickly that we can correct these errors before a word is even finished. What we hear or see, or smell is made up of so much more information than just the input from a single sense.
Think about this the next time you have trouble understanding someone when they talk on the phone or your voice sounds strange when you have a cold. You can even record your own voice reading something when you are listening to music or not listening to anything at all. Do you sound any different? See what you can find out!

Our eardrums appear to move to shift our hearing in the same direction as our eyes are looking. Why this happens is unclear, but it may help us work out which objects we see are responsible for the sounds we can hear.
Examining 16 people, the team detected changes in ear canal pressure that were probably caused by middle-ear muscles tugging on the eardrum. These pressure changes indicate that when we look left, for example, the drum of our left ear gets pulled further into the ear and that of our right ear pushed out, before they both swing back and forth a few times. These changes to the eardrums began as early as 10 milliseconds before the eyes even started to move, and continued for a few tens of milliseconds after the eyes stopped.
The eardrum movements that follow the change in focus may prepare our ears to hear sounds from a particular direction.
