1. Launch BioSigRZ.
2. Click the File menu and click Open Config. File.
3. Browse to and open one of the following files:
C:\TDT\BioSigRZ\Configs\ABR\Root_ClickAbr.acf
A 0.1 millisecond, single-channel mono-phasic click will be presented at a rate of 21
presentations per second. With each successive presentation, the click phase will alternate
between a condensation and rarefaction click to eliminate potential speaker artifacts. Click
Tone pips are typically presented at multiple frequencies to
target more specific areas of the subject's hearing range. Tone
ABRs take significantly longer to perform (typically up to
around 40 minutes) but provide more data.
