Maximum masking levels:
Insert phones: 110dB SPL, relative levels 0 to -40.
Headphones: 110dB SPL, relative levels 0 to -40.
Insert phones: 110dB SPL, relative levels +60 to -40.
Absolute Masking Level:
0dB to 110 dB SPL absolute level. The masking level is only
presented in SPL, and can therefore not exceed the loudness of
the stimulus. E.g. a stimulus presented at 100dBnHL, and relative
masking level at 0dB would provide a masking level of 100dB
peSPL. This would equal a level 75dBnHL.
Maximum masking levels:
Insert phones: 110dB SPL, relative levels 0 to -40.
Headphones: 110dB SPL, relative levels 0 to -40.
Insert phones: 110dB SPL, relative levels +60 to -40.

Data collection:
Impedance test,
Waveform buffer (A/B, Contra, Ipsi-Contra, A-B = Noise),
Curve (Hide, Fixate, Merge, Delete),
Online EEG,
Waveforms storage in unlimited storage database.
Data Recovery:
Lost data due to crash of Windows® will in almost all cases be
available upon re-establishing Windows® operation.
Note ! The transducer is dedicated to one Eclipse only! Calibration is stored on the Eclipse. Replacing the
transducer will require new calibration of the transducer connected to the Eclipse.
