The Duet device with SmartEP can be used as a single channel system with automatic switching of the polarity from negative to ground for the acquisition of ABR waveforms. The following guide outlines the steps to take and the correct cables to use before proceeding with ABR acquisition.
These application notes can be used as a quick guide to perform specific tasks while using IHS hardware and software.
Certain users, specially researchers, may find at that they need to port their data to a different program or format, for analysis or storage. SmartTrOAE data has multiple ways to export the data, from exporting a single recording, multiple recordings on a single file, or suppression analysis data.
When building new normative data sets, or for researchers wanting to aggregate peak data, the Peak Extraction Utility can help gather the peak label information, including latencies and amplitudes into a single worksheet for easy analysis.
Certain users, specially researchers, may find at that they need to port their data to a different program or format, for analysis or storage. SmartDPOAE data is stored in text format in the directory that corresponds to each patient; however, the file extension is not “.txt”. This SmartNote details the way to locate and copy the data, as well as list the definition of the data contained in the DPOAE… Read More »Exporting Raw Data from SmartDPOAE
Certain users, most commonly researchers, may find at some point that they need to port their data to a different program or format, for analysis or storage. SmartEP data is stored in an encrypted proprietary format in the directory that corresponds to each patient; however, the data can be exported to a text file using options built-into the SmartEP program. Data may also be exported for SmartEP-ASSR and SmartTrOAE in… Read More »Exporting Raw Data from SmartEP
This document shows the procedure that can be used by field technicians to calibrate transducers to be used with IHS equipment. These calibration values are then applied by the software automatically when performing tests using these transducers for stimulation.
SmartEP, SmartEP-ASSR, SmartEP-CAM, Intelligent VRA, and Smart Audiometer have the ability to use custom created stimuli, such as speech. Before use, the stimuli must be converted from WAV format to the IHS proprietary stimulus file format. This Smart Note defines the requirements for the WAV files, the steps to convert the stimuli, calibrating the files before use, and some additional usage tips for individual programs.
During otoacoustic emissions suppression, the stimulus is alternated between a masking white noise signal and a click signal; where the recordings are acquired in response to the click stimulus. By comparing a suppressed transient OAE recording to one that is acquired normally, conclusions can be drawn about the workings of the efferent nerve fibers and the suppression of sound. The suppression noise masking addon for SmartTrOAE is available for the… Read More »TEOAE Suppression in SmartTrOAE
The following Smart Note covers the basics for the acquisition of TEOAE responses, including Spontaneous OAE, using the SmartTrOAE software. Topics includes recommendations for probe usage, test settings, result analysis. SmartTrOAE is available for the Duet, USB, and USBLite hardware platforms.
This Smart Note contains the basic instructions and workflow for acquisition of Otoacoustic Emission screening results using the SmartScreener-Plus 2 software for the Solo, USBLite, and Duet hardware platforms, including recommendations for placing the OAE probe.
