No, not yet, I'm just doing some banking at the moment paying the bill
for this season. I think in a week or two the boat comes out of it's
winterbox and I then have to give it a last paint before it goes in the
water.
I have bought me the soundman classic studio binareal mics to use for
this project. I did some recordings with this set, even yesterday in an
arboretum, and I was about to spool them to the computer. but I find
very little time to experiment and find out whats possible and what not.
Maybee you want to have a day off sometime this spring and join for a
day of sailing? I'm not pressed on time whit this project, it's just
something i want to do.
I'll tell you when the boat is ready ??

Subject: Peculiarities of sound propagation


We have in the past considered at length, the problems peculiar to nature
sound recording arising from the fact that the real world does not provide
the controlled conditions of a recording studio.  That no matter how good
our equipment and techniques, we are faced with the situation that the soun=
d
reaching our microphone(s) is likely to be different from that which left
the source.

I don't wish re-open that discussion, but simply report a situation right
here in front of my computer - at 8:00 AM, March 17.

My head is one metre from an open window - albeit screened with wire gauze
to frustrate our Brisbane mosquitoes.  Somewhere between 5 and 10 metres
from the window, and approx. on the same level (c. 4 m above ground), as fa=
r
as I can tell, a cicada is singing - a continuous buzz that goes on for
minutes at a time.

I hear it plainly though not loud.  However, if I move my head half a metre
further away from the window, the sound cuts out completely, at least to my
ears.  Somehow interference (out of phase?) is cancelling the sound.  This
confirms that the position of a mic can have a considerable effect on a
nature recording, quite apart from the obvious effect of attenuation of a
signal with distance from the sound source, and consequential deterioration
of signal/noise ratio.

BTW, I wonder if in other languages there are interesting common names for
cicadas.  Because of their songs, cicadas attract the attention of children=
.
And children come up with some delightful names - Black Friday, Floury
Baker, Razor Grinder, White Drummer, are some of our local ones here.  I've
not managed to find the cicada singing outside my window, but choosing from
among the song descriptions in our State Museum's book "Wildlife of
Brisbane", my guess is that I have a "Brown Bunyip", Tamasa tristigma.

For non-Australians, a Bunyip is a mythological creature, a sort of swamp
version of the Loch Ness monster, given to appearing above the surface of
the water at night and making very strange noises.  (I don't suppose you
found any bunyips in the outback, Walter?)
