How to get a clean Auditory Brainstem Response ?
Posted: Mon May 30, 2011 9:52 pm
Hello,
I have the ABR system and using it in speedmode 9 to collect ABR to click sounds. I have some trouble obtaining a clean response that could be compared to a clinical ABR.
I found this nice graph on your website
http://www.biosemi.com/abr.htm
You provide some details about how you generated this nice waveform, but I would like to know more, could you tell me what was the intensity of the click and some extra information about the recording setup that was used ? Also what are the online filters and other parameters ?
Or/and put me in touch with the person that did this recording ?
Thank you very much in advance for your help,
Regards
A.
ps : The information provided on your pages mentions (8192 sweeps), left ear (blue) has masking noise, right ear (red) has clicks at 19 Hz
