Eclipse Additional Information
Q: How is the unit calibrated?
A: At the factory a 711 coupler is used (IEC 60318-4 occluded ear simulator).
You can also use a 2cc. IEC126 and 6cc. IEC303 please follow the instructions from technote 0114.
Interacoustics will supply correction data allowing a 0138 coupler from B&K to be used to obtain the
same calibration results for servicing purposes. When entering calibration mode you will find info there
on the two possible calibration systems peSPL and nHL. For nHL click we subtract 35.5 dB to arrive at
nHL from peSPL.
For Tone Burst you can enter one calibration value for the type of Burst you prefer to use. Often that is
manual 2-1-2 or the quite similar 5 sine Blackmann. We therefore deliver the unit using peRETSPL
correction values (correction when compared to peSPL) from ISO 389-6 (2007) for Tone Bursts.
Q: How is masking calibrated?
A: The white noise WN used for masking level is provided in SPL. For WN used as a masker for typical
ABR stimuli, the WN SPL level can be considered to be close to effective masking level. The important
exception from this rule of thumb is, that 500Hz TB and 500Hz NB CE-Chirps® require slightly higher
masking levels of around +10dB.
Q: I have measured in the wrong patient name – can I transfer patient files between patients?
A: Patient files can be transferred between patients if a clinician accidently tested a patient under another
patient name. Below is a description of the workaround.
CAUTION: You must ensure to have a copy of the patient before the below is tried out!
1. Export both patients from OtoAccess
2. Under Notepad (win7/8) open the patient you want to copy from
3. In the exported person's file you want to copy the session from highlighted in blue below, starting
from the first line: <xmlinfo>, all the way to the end of the document.
4. Paste the entire session element in the patient you want to copy to (starting at the bottom of the
document).
