Innovative solution for virtual audiology training

Intelligent Hearing Systems is pleased to offer SmartVS™, a Smart Virtual Simulator software suite for audiology training. SmartVS™ is based on the user-friendly interface of our full-featured auditory diagnostic testing modules. SmartVS™ provides a realistic, virtual, testing environment from appointment scheduling to diagnostic testing, report generation and billing.

The audiology simulator you’ve been waiting for

SmartVS™ is the only virtual simulator designed for use in audiology training and requires no additional hardware. Individual semester licenses can be procured by a student and installed on the student’s own Windows computer. The package includes a companion PDF book with basic concepts, recording procedure explanations, exercises, and additional readings and references

Streamlined workflow

Realistic patient workflow including appointment list, demographic data entry, history taking, testing, report generation and billing. Testing modules include:

  • Otoscopy
  • Tympanometry
  • Acoustic Reflex, with and without Decay
  • Auditory Evoked Potentials (air & bone conduction)
  • Auditory Steady State Responses (ASSR)
  • Distortion Product Otoacoustic Emissions (DPOAE)
  • Transient Evoked Otoacoustic Emissions
  • Audiometry

User-friendly features

  • Easy Access to all parameters from a simplified control panel and streamlined menus
  • Improved toolbar and button design for fast access to key features
  • Quickly load your own or preset protocols
  • Change most test parameters with a single click
  • Copy patient image and setup to clipboard easily for use in report generation

Virtual testing room

Begin your evaluation by selecting examination tools and supplies from the virtual tool cabinet. Once in your virtual hands, move and place them on the patient. Virtual testing room experience features:

  • Comprehensive tool cabinet including an otoscope, tympanometer, skin preparation supplies, transducers, electrode leads, and electrodes
  • Perform and view virtual otoscopic exam
  • Perform and view simulated tympanometry test
  • Simulate patient skin preparation and electrode placement: resulting impedance and recordings will depend on how well the patient’s skin was virtually prepped, and where the electrodes are placed
  • Practice polarities and electrode cable connections to the amplifier, including use of Y-adaptor jumper cables: incorrect connections lead to acquiring waveforms with inverted, diminished, or absent morphology.

Comprehensive patient profiles

Complete library of virtual patient profiles representing various pathological conditions. Includes over 40 patient profiles with:

  • Demographic information and photo
  • Otoscope image and Tympanogram for each ear
  • Air conduction & bone conduction thresholds
  • Auditory evoked potential responses
  • Patient state at the time of testing
  • History tab for patient background

Patient profiles can also be generated, customized, and shared with students and peers.

Audiometer features

Audiometer simulator is based on the user-friendly SmartAud screening audiometer. SmartAud Virtual features:

  • Present stimuli by right-clicking at the point on the audiogram that needs to be tested
  • Patient responds in the test room and by pressing the virtual response button
  • Mark thresholds easily by using one of the score buttons or using a keyboard shortcut
  • Stimulate clicks, pure tones, warble tones, or words
  • Includes lists of spondee words for use in speech recognition threshold (SRT) and word recognition score (WRS)
  • Generate audiograms for air conduction or bone conduction
  • While using practice patient profiles, check your progress by using the feedback feature

OAE features

OAE testing simulation is based on the easy-to-use SmartTrOAE otoacoustic emission acquisition system. SmartOAE Virtual features:

  • Acquire Transient Evoked OAE or Distortion Product OAE
  • Current meatal response shown live
  • TEOAE responses include a pass/refer determination for overall, and for the main frequency bands
  • TEOAE graphs include waveform (time domain), frequency domain conversion
  • Time-Frequency analysis graph to visualize the TEOAE responses in different ways
  • DPOAE responses can be acquired by an automated protocol or customized script
  • Customize all DPOAE acquisition parameters, from start and end frequencies to stimulus levels and frequency ratios
  • Data for both TEOAE and DPOAE responses may be viewed in table format and exported for further analysis

AEP features

AEP testing simulation is based on the user-friendly SmartEP evoked potential system, the preferred choice for recording auditory evoked potentials. SmartEP Virtual features:

  • Easily mark waveforms using over thirty predefined peak labels, or create your own custom labels. Easily adjust them using a mouse or keyboard
  • View latencies and amplitudes of peaks directly on waveforms and in newly embedded recording information panel
  • Automatically arrange recordings by intensity, acquisition order, stimulus frequency, or rate
  • Easily view ongoing EEG display for quick assessment of patient state during testing
  • Latency-Intensity graphs indicating normative data ranges are automatically generated from marked waveforms
  • Quickly add, subtract, invert, time shift, or cross-correlate recordings

ASSR features

Auditory Steady State Responses can be acquired using the acquisition module based on SmartEP-ASSR.

  • Simultaneous, multi-frequency testing
  • Easily change between different combination of stimulation of the most frequently used audiometric frequencies
  • Includes masking options
  • View phasor and frequency spectrum diagrams for each waveform
  • Activate phase and harmonic criteria for data analysis
  • Automatically generate audiograms based on the responses on the page
  • Analyze individual waveforms and each of their response components
  • Set stopping rules based on SNR and Residual Noise
  • Includes a Phase-Intensity analysis visualization tool
  • View the audiogram in SPL, apply a general HL correction table, or use regression formulas for HL correction
  • Automatically arrange recordings by intensity, acquisition order, stimulus frequency, or rate
  • Easily view ongoing EEG display for quick assessment of patient state during testing

AEP parametric model

AEPs and ASSRs are generated on the fly based on a parametric model that adjusts peak latencies and amplitudes based on stimulus parameters, pathology, and electrode placement.

  • Intensity Function
  • Rate Function
  • Stimulus Frequency Function
  • Stimulus Rise Time
  • Stimulus Duration
  • Montage: Ipsilateral, Contralateral, Horizontal and Midline
  • Pathologies: Conductive, Sensorineural, Retrocochlear

Stimulus Visualization Tool

Students can learn more about the stimuli being presented by using the StimGen visualization tool

  • Play with levels of amplitude, frequency, and duration to define the stimulus component
  • Choose between multiple envelope windows to see their effects on the components
  • Add multiple components to see the interactions between them and see a complex resulting stimuli, such as the ones used for eliciting multifrequency steady state responses
  • Visualize the spectrum of the stimuli as relative amplitude or in decibels
