  • NEW! “Auditory Steady-State Response (ASSR)” simulator. Perform air- and bone-conducted ASSR testing using single or multiple AM, AM/FM, and AM2/FM stimuli across modulation frequencies from 1-600 Hz and carrier frequencies from 20-20,000 Hz.
    – ASSR simulator also accounts for cross-over hearing and masking, simultaneous masking when using multiple stimuli, upward spread of masking, and more.
  • NEW! “Acoustic Reflexes” and “DPOAE” simulators
  • NEW! “Simulate case” tab extends audiogram frequencies for simulating cases
  • NEW! “Case Report” is used to type in case history, report behavioural and HERA results, summary of findings, and make recommendations.
    – auidgrams, DPOAEs, and tymps are automatically graphed and populated on “Case Report” tab
    – DPOAE chart defines test freq and response present(RP), no response (NR), and abnormal (ABN)
    – Tympanomtery chart shows measures of ECV, SA, TPP, and TW
    – Save to .jpg for import as a figure into another document

Minor Updates
– Patient Setup has 2D prep to improve prepping patients by reducing the computation demands on lower-end graphics computers.
– switch between 2D and 3D patients
– quickly change head views: ‘front’ ‘left’ ‘right’ ‘top’ ‘back’
– prepping and electrodes placements on 2D heads are not updated on 3D heads, and vice versa. Prepare and place electrodes either in 2D or 3D.
– electrodes last placed on either 2D or 3D patients take precedence for computing electrode impedances
– patient panel can be dragged around screen by clicking on “drag” bottom left corner or resized by clicking on “resize” in top right corner
– added selection “patient centric” to display Patient-centric AEPS results such that “left plots” display “right channel recordings” and vice versa. This was done to be consistent allow consistency with behavioural results displays.

– added “AutoSave Rate(min)” to allow for auto saving the case at user defined intervals. Note, saving cases with many AEPs files may take a lot of time. To compensate, save less often.
– added 2D and 3D head models for male and female sex phenotypes; future updates will include more gender inclusive head models
– added in cross-over masking to test ear when using contralateral masking for behavioural and AEP testing
– renamed “Save AEP” to “Save Case” and “Load AEP” to “Load Case” as well as moved them to top menu button bar
– these save the enitre case file’s data: AEP and behavioural
– added menu for selecting patient’s sex
– added button to “Reset buttons” in case an error occurs and user needs to revert the buttons back to being enabled.
– corrected SDR RN criterion for CAEPs to be 0.965 uV = 1.93uV/2 to yield at least and SNR~=2 for a ~2uV N1-P2 near threshold –> based on Van Dun, B., Dillon, H. and Seeto, M., 2015. Estimating hearing thresholds in hearing-impaired adults through objective detection of cortical auditory evoked potentials. Journal of the American Academy of Audiology, 26(4), pp.370-383.
– added button “Apply to All” pages to apply current page setting to all pages
– set default RN criteria for CAEPs to be more realistic
– made a button for “apply settings to all pages” to change all pages to have the same Xscale and Yscale as the current page
– in “Patient Setup” –> turned on “Auto Apply” for assignments to allow an option so that those users who have low-end graphics cards can apply electrodes in a timely manner.
– added “birth date” and “Today’s date”
– added buttons to “Add Title” above AEP waveforms
– added ampltidue scale value to vertical axis
– changed default click ABR intesnity to 90 dB nHL
– can change x- and y-scale limits on EEG display

Bug Fixes
– Fixed: ASSR were still present for “clamped” tube recordings. This only occure in v2.1 and v2.2
– Fixed: rate effects for click ABRs were not properly implemented. Click ABRs now have evident latency shifts with changes in stimulus rate.
– Fixed: if using Assign#2 to load in audlt patient, then error occured with patient setup showing infant 3D head. this has been corrected.
– Fixed: stats interval for CAEPs for adults when saved in Assign#2 were defaulted to infant intervals of 100-450ms. Now set to proper values when loading patients of different ages within the assignment.
– Fixed: CM were incorrectly absent for moderate-severe threshold elevations
– Fixed: Saving AEP pages using “Save Page” now saves pages to specific file.
– Fixed: Clearing markers would cause other markers on that waveforms unmoveable until waves were reploted. Can now clear markers and all other markers are moveable.
– Fixed: During random generation of audiograms, true air-bone gaps could sometimes be as large as +/-15 dB for typical hearing but are now set to within +/-5 dB.
– Fixed: ANSD between 0-30% would lead to an enhancement of ASSR amplitudes. This has been fixed.
– Fixed: wave V’ was reduced in amplitude for click stimuli thus making Wave V-V’ smaller than expected based on normative data. Now fixed.
– Fixed: recordings would continue and unable to be stopped when patient woke up at end of session
– Fixed: when reloading report the waveforms were plotted with saved filter settings. This is now fixed such that waveforms are plotted using the saved filter settings.
– Fixed: SP/AP ratio was accidentally inverted and calculated as AP/SP in EcochG table listed at bottom of plots. Now is correct: SP/AP ratio
– Fixed: “clear marker” issue when clearing marker some other markers could not be moved. Now fixed.
– Fixed: For added “Text” maerkers, if “rename marker” was done the marker label would revert back to original label once it was moved. Renamed markers now keep the renamed string. Note, renaming peak markers will still revert back original peak labels when moved.

 


SimHERA v2.2 — Minor update (February 16, 2021)

Brief description of Update to v2.2  — Bug fixes.

Minor updates
– In “Open Mode”, users can change recording “Sample Rate” to show all AEPs (ABR, MLR, CAEP) in one CAEP recording. Set this to high value to visualize all AEP components. Careful, this can take time
to record when collecting many trials on a low-end computer. Recommend only changing this for demonstration purposes.

Bug Fixes
– fixed: crashing when loading AEP reports
– fixed: Summating Potential amplitudes were sometimes 10x too large for click-ABR –> they appeared like early wave I.
– fixed: “Noise Fluctuations” were being reset to constant 1.0 after collecting first recording.
– fixed: MLR Awake state and EEG noise were set too low.
– fixed: dragging SDR & Avg markers were throwing an error.

 


SimHERA v2.1 — Major update (February 4, 2021)

SimHERA now includes a Middle-Latency Response (MLR) Simulator!

for more information, please contact aherdman@audiospeech.ubc.ca

Brief description of Update to v2.1:

Major Updates

  1. MLR simulator now included – basic MLRs across ages. MLR adjustments for neurological involvements will be added in future versions.
  2. added multiple AEP components within the following AEP type recordings for improved realistic simulations. SimHERA’s AEP types are (new additions are in blue):
    • EcochG = CM, SP, AP, ABR waves II-VI, and ASSR (as in previous versions)
    • ABR = CM, SP, ABR waves I-VI, PAM reflex, and ASSR (as in previous versions)
    • MLR = CM, SP, ABR waves I-VI, PAM reflex, ASSR, Na, Pa, Nb, Pb (CAEP’s P1), N1 (CAEP’s N1) <– new MLR simulator
    • CAEP = CM, SP,  ABR waves I-VI, PAM reflex, ASSR, Na, Pa, Nb, P1, N1, P2 (as in previous versions), N2
  3. reduced demand on GPU(display) and CPU with the following changes
    • users can change “Update Time (sec):” for the EEG display, slower times reduces demands on computer’s CPU and GPU
    • users can change “Acquire Update Time (sec):” when acquiring AEPs online, slower times reduces demands on computer’s CPU and GPU
  4. users can now move organize plotted waves while acquiring online. Future updates will allow waveform markings to be made while acquiring online.
  5. improved simulations for tone-evoked Cochlear Microphonic (CM); higher freqs (>2kHz) have smaller CMs amplitudes

Minor Updates

  1. In “Patient Setup”, electrode and prep buttons change color of text when selected to make it more obvious for Mac OS users to see when buttons are “on” and “off”. Also, these buttons can be sequentially pressed so no need to click them ‘Off’ to move to next button.
  2. users can now test situations when mastoid electrodes are incorrectly placed on wrong sides. This results in improper (opposite) ipsi-contra AEP recordings.
  3. when preparing skin for electrode placement, patients will provide feedback if too much abrading occurs. Look for their response above their head.
  4. While acquiring online, recording duration “Recording Time (sec)=” is updated just under the “Acquire Update Time (sec):” selection
  5. Less color change on the scalp when preparing skin using alcohol or prep pad. Electrode impedances were slightly changed to accommodate this.
  6. all marker buttons now visible and enabled for marking waves regardless of the AEP type selected

Bug Fixes

  1. Bug fixes for contralateral recordings:
    • when collecting dual channels (“both”), Fsp values were incorrect. Now corrected.
    • when collecting only “contra” recordings, they were actually “ipsi” recordings. Now corrected. Previous versions were correct when collecting “both” channels.
  2. dragging waveforms off the screen will not occur anymore. They will hit a floor or ceiling position. This is to stop waveforms from being lost beyond the page limits.
  3. When leaving “Patient Setup & Tympanometry”, the popup “datacursormode” box could remain open in bottom right corner of the screen if an electrode placement button was still set as “on”. This popup box now automatically closes when leaving the patient setup.

SimHERA v1.2 — Major update (October 10, 2020)

– auto-screen resize based on computer’s screen resolution
– users can now rescale “FontSize” suitable for their own display and viewing preference. See editable box in top right-hand corner of SimHERA
– users can auto-apply electrodes during patient setup using a saved file for default adult and infant electrode placements
– loading in datasets are now backward compatible to SimHERA v1.0
– after loading in new SimHERA_v12.mat file format, the “Update AEP State”, “EEG”, “60Hz Noise”, and “HFNoise”, “rejection limits” will be set to the values that they were when saving a new SimHERA_v12.mat dataset.
– fixed impedance values to show up correctly after loading in previously saved datasets
– impedance values are now more realistic with the amount of skin preparation
– fixed bug when performing click-evoked CAEPs. Can now collect CAEPs to clicks with proper SDR intervals
– added a “Wake Up” button to change infant/adult state when wanting to perform CAEP collection. Note, there is no “go back to sleep” button so once the patient is woken up, they stay awake. To reset the sleep and noise states across the session, you must turn on the “update AEP state” radio button and select the AEP type of your choice from the drop-down menu “AEP Type”.
– Fixed bug when EEG radio button first selected. The Y-scale limits on the EEG axes would automatically change with the maximum amplitude of the ongoing EEG. Now set to proper limits for the AEP Type selected.
– Fixed bug that now properly resets electrodes impedances between EcochG TM electrodes to mastoids when selected ABR or EcochG Type
– improved support for low-level graphics cards

SimHERA v1.0 — Major update (August 6, 2020)

SimHERA is our next generation of simulation software for Human Evoked Response Audiometry and it includes our inaugural sABR software. There are MANY new features in SimHERA such as simulators for electrocochleography(EcochG), cortical auditory evoked potentials (CAEPs), and tympanomtery. SimHERA also comes with patient setup for electrode preparation and placement on 3D head models which determines the electrodes’ impedances and common-mode rejection ratios that affect amount of EEG noise.

SimHERA is a free update for those who purchased sABR before August 6, 2020 with an added surprise bonus!

 

There are two ways to install SimHERA: 1) Automatic and 2) Manual Installation. If you have troubles with Automatic installation, please try the manual installation procedures (see below).

  9. Double-click “SimHERA_2021_v3x.exe” to initialize SimHERA and obtain your “unique two-number SimHERA code” (e.g., 1973 3180) that is specifically linked to your computer. This SimHERA code is needed for licensing. The SimHERA code is a mathematically unique code based on your computer’s ID and hardware configuration. It contains no identifiable information about you, your computer, or your network. It is therefore safe to transmit across the internet via email. Note: If you change your computer’s motherboard or make other major changes to its hardware, then you will need to obtain another license. aherdman@audiospeech.ubc.ca.
  10. email the SimHERA code to aherdman@audiospeech.ubc.ca to receive your license file to run SimHERA on your computer. Note: you will need to place the license file within the installation directory of the SimHERA application (e.g., default directory “C:\Users\****\AppData\Roaming\UBC\SimHERA_2021_v3x\application” where *** are usually the user’s login name). Also, the license file must have the exact name that was sent to you. For example, the internet license file should have the file name = “simHERA_license_file_Internet.lic” and should NOT be a shortcut to the license file. Often your computer will add a number at the end of the file name (e.g., “simHERA_license_file_Internet (2).lic”) if you downloaded the file more than once. The trailing ” (2)” must be removed including the space before the parentheses so that SimHERA can read the proper file and run.
  11. After placing the license file in the application folder. Go to the SimHERA folder and rerun “SimHERA_2021_v30.exe” application.

 

Mac OS (Mojave 10.14, Catalina 10.15, Big Sur 11.0):

Trouble Shooting Mac OS installation:

  • Running the SimHERA installation from your desktop may not work due to permission settings if you are not the administrator user (aka super user). If this occurs then place the SimHERA installation application in the “Applications” folder and try to run it from there.
  • Mac OS is often set to not allow third party applications to install. You will need to change your Mac OS security setting to allow for third party app installations. Here is a guide on how to get your “Allow apps downloaded from:” “Anywhere” selection back. https://www.youtube.com/watch?v=xFpVqkyXFy4 (Disclaimer: This link is for educational purposes only and I hold no responsibility for any damage to your computer. It is recommended to disallow third-party app once SimHERA is installed.)

For example, the internet license file has to have the file name = “simHERA_license_file_Internet.lic” and can NOT be a shortcut to the license file. Often your computer will add a number at the end of the file name (e.g., “simHERA_license_file_Internet (2).lic”) if you downloaded the file more than once. The trailing ” (2)” must be removed including the space before the parentheses so that SimHERA can read the proper file and run. In addition, make sure there is only one “.lic” file within this directory.
  11. After placing the license file in the application folder. Rerun “SimHERA_2021_v21.app” application.
