Re: tympanometry probe tone level?

[Jeremy Federman <jeremy.federman@xxxxxxxxxxxxxx>]

Hi - 

I suspect it depends on the frequency being used (and maybe the equipment,
too), but I believe the probe tone level at the standard 226 Hz should be 85
dB SPL plus or minus 1.5 dB.  For additional calibration info, you could
check the ANSI standard...

With kind regards, 

Jeremy
