Using the Peak Extraction Utility

  • General

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.

Exporting Raw Data from SmartDPOAE

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

Exporting Raw Data from SmartEP

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

System Calibration for ER3A and 10D

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.

Using the Stimulus Conversion Utility

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.

TEOAE Suppression in SmartTrOAE

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

Transient Evoked Otoacoustic Emissions with 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.

Data analysis using SmartScreener-Plus 2

SmartScreener-Plus 2 includes some tools to obtain statistical analysis of the infant hearing screenings that were performed, including passing rates, noise levels and individual screener performance. This Smart Note covers the instructions on how to generate such report and understanding the information that is included in it.
