Sorry, I misspelled anthropophony, again. Corrected in the text, now.
For the past four weeks, with five more to go, I=92ve been (and will be) le=
cturing across Europe and the UK on the subject of Soundscape Ecology and h=
ave picked up a few pointers, so far, along the way.
First and foremost, the term, anthrophony, that Stuart Gage (Emeritus, Mich=
igan State Univ.) and I first published after our National Park Service stu=
dy program (2001-2) was published, is not correct. We thought that the pref=
ix, anthro, meant human. But, alas, it doesn=92t. The root literally means =
cave, in Greek. And we ain=92t speaking about the sound of caves. The probl=
em was called to my attention by several French colleagues in both Quimper =
and Paris, where I was speaking, that if we wanted to express human sound, =
then the word needs to be anthropophony. The addition of the =93po=94 in th=
e middle, is essential. (Note: the term was correctly translated in the Fre=
nch edition of The Great Animal Orchestra).
Second, a new piece of gear was called to my attention that some may have a=
lready checked out. But for those who haven=92t, give the new RME: Babyface=
