Dear list:
we want to use Békésy tracking (with a constant change in frequency) to
measure absolute thresholds as a function of frequency in a study
involving tinnitus patients. The stimuli will be 300-ms tone bursts.
Now I do remember that for the level change a rate of 2 dB/s is used
frequently -- but what rate of change in frequency (oct/s) should one
opt for?
I'm sure that many of you have experiences with this procedure - which
parameters do you use?
Above that, is there anyone who would be willing to share some MATLAB
code for Békésy tracking - seems there's no need for re-inventing the
wheel...
Best regards,
Daniel
