When do you do test mode
when HA initially comes in
quality assurance before fitting
compare to manufacturers specifications and ensure HA is within ANSI tolerance
When do you do user mode
patient comes in for a follow-up
speech map
compare to previous user settings and ensure HA is still working properly
When do you use the blue coupler
ANSI test
When do you use the silver coupler
I/O and directionality
If the patient reports that loud sounds are too soft, there is ____________ compression
too much compression
If the patient reports that soft sounds are too loud, there is _______________ compression
too little compression
How to look at shape of curve/values to estimate HL
Subtract the 60 dB SPL input
Estimate outputs
Multiple gain of — to —- dB by 3
Go to 2k Hz
Avg gain at 60 dB (output)
Multiply value by 2
OSPL90 on specs sheet
maximum dB SPL
Avg OSPL90 on specs sheet
HFA dB SPL
