From Martin van Raay, Culemborg, The Netherlands
Jason Arunn Murugesu reports on why you can stay focused on conversations in a noisy room. This made me wonder why people, if you gather more than, say, 10 in a room, start raising their voices (17 June, p 13).
If everyone spoke at a normal level, no one would have to shout. So STOP SHOUTING! Please.
