G'day all,

A sideline on the point about the pitch of the call "air ball" (mentioned on the posting from steve t, on 04-May-98.

If the researcher believes the pitch is influenced by the frequency of the lighting (and its hum), he could check to see if the call occurs in countries (such as Australia, UK, etcetera) where the mains frequency is 50 Hertz, not 60 Hertz, and see if there is a commensurate lowering of pitch.

I can't give any firsthand gen on this one as I have never seen a basketball game in the flesh - and such TV coverage as I see in passing does not concentrate on the audience. (Generally, you can't hear much at all over the commentators.)

Regards,

Bob Bolton
