Input levels sliders allow for adjusting the input level to 0 VU for the selected input. This ensures that correct calibration is obtained for Mic1,
Mic2, CD1, and CD2.
WR1 , WR2 and WR3 (Word Recognition) allows selecting different speech list setups as defined by the selected protocol. The labels of these lists which go along with these buttons can also be customized in the protocol setup.
Selecting HL, MCL and UCL sets the symbol types that are currently in use by the audiogram. HL stands for hearing level, MCL stands for most comfortable level and UCL stands for uncomfortable level.
Each type of measurement is saved as a separate curve.
Binaural and Aided function allows for indicating if the test is performed binaurally or while the patient is wearing hearing aids. This feature is only active in the Speech Audiometry screen.
