Karen Wicklund: You mentioned at the very start of
your talk that there were not a lot of studies done about the effects
of hormones on the singing voice throughout the cycle. Indeed I’ve
actually done 2 myself; one at Washington State University and one
at Northwestern University. They’re reported in the May/June
1996 NATS Journal, (that’s the Northwestern Study), also the
September 1998 Medical Problems of Performing Artists. Audio

John Nix: It seemed to me that the Yasmin®, by basically stabilizing
the levels of estrogen and progesterone, the one variability then
that you saw during the luteal phase when they were on that vs.
the placebo, the follical stimulating hormone, FSH, would be the
one thing that was not stabilized by using the Yasmin®; maybe
that’s related to the changes you saw in closed quotient?
Is that possible? Audio link.

Ron Scherer: Just a couple of quick things: Do you plan to actually
do perceptual judgements of voice quality? [Lã: Yes I do]
OK, so the term "voice quality" actually is appropriate
here. Closed quotient, of course, is not a voice quality measure
per se. You seem to be linking those. The other comment: were any
of these females vocal fold tissues looked at? [Lã: no they
were not] Their fundamental frequency, are you going to measure
that? [Lã: yes it was]. A little swelling of the vocal folds
would tend to increase the closed quotient ...listen to audio for
further discussion. Audio link. |

Theresa Brancaccio: Did you have the singers explore the extremes
of their upper ranges? Because I know there is a concern that at
the top, the very upper notes could be lost, and there is a concern
about also darkening of the voice that would be permanent. Audio
