When these contractions start to run into one another, people just start to make wheezing sounds. As we force air out under much stronger pressure than when we are speaking normally, we also start to produce sounds with much higher pitches than we find during normal speech.
This means that when people start to laugh hard, they start to make sounds that we never normally hear in any other context — when I laugh hard, the pitch of my voice goes much higher than my speech. And if we are speaking, or trying to speak, the effect of the laughter will be immediately apparent, as we start to lose control over the muscles in our rib cage, that normally work with such precision during speech.
After a few seconds further talking, during which he asks Agnew to stop laughing Aggers, do stop it! You can actually see the pitch of his voice subsiding as Johnston gets control back over his speech I made a very short video about the acoustics of their laughter here. But the really striking thing is that they were laughing at all.
