Apologies with that Ben Goldacre inaugural lecture - he's talking to a hall and it is fine if he raises his voice. However, the lavalier microphone he wears overloads or gets close to it every time he shouts. Plus I think if you squeezed him hard enough he'd squeak. Which is quite jarring, but I think it is worth perseverance because what they're doing there, with a little imagination, could be applied to so much more. Plus it's all very admirable.
