The research module

Export waveforms

With the click of a mouse, select the recording to be exported in its averaged state, as presented on the screen. The exported waveform or session is saved in a XML le on the hard drive. The XML- le can be viewed in Microsoft® Excel, MATLAB® or similar analysis software.

The export waveform/session function is available on saved recordings that are created on an Eclipse with the Research Module license, even when viewed on another PC. This gives the exibility to collect data in one location and analyse in another without the need for a connection to the Eclipse.

Import wavefiles

The Research Module allows you to import WAV les, which can be used as stimuli in any ABR test.

• Add a speech sound for cortical testing
• The speech stimuli, Da, Ba and Ga are included for any ABR or MMN test
• Custom WAV file stimuli can be calibrated and a peRETSPL - nHL correction value can be specified, as with traditional stimuli
• Combine two different WAV files to create an alternating polarity stimulus
• A WAV file can be specified as a continuous stimuli and used as masking noise

Data logging

The data logging function allows all sweeps to be saved (logged), permitting the entire recording to be “replayed” in analysis software such as Microsoft® Excel or MATLAB®. From here, multiple test parameters can be modi ed (e.g., change the ltering or apply weighed averaging in a replay of all the sweeps) and the resulting waveform reassessed.

The logging can be applied to both custom research protocols or the standard default protocols. The logged sweeps are saved in three text les on the hard-drive.
