International Evoked Response Audiometry Study Group (IERASG)

In the early phase of hearing and speech development, it is of central importance that clinicians are able to reliably determine the type and degree of hearing loss in order to begin early with therapy and (re)habilitation within a sensitive period of auditory and brain development. Auditory brainstem responses (ABR) and auditory steady state responses (ASSR) are the pillars of pediatric audiological differential diagnosis. With appropriate stimuli and protocols, frequency specific information can be acquired in infants and appropriate amplification can be provided at a young age. The workshop will focus on the physiological basics and practical clinical hands-on training to perform and interpret ABR and ASSR measures. In this workshop, we will address technical specifications regarding stimulation and recording parameters settings as well as non-technical factors. The practical performance of ABR- and ASSR-measurements will be demonstrated live.

This hands-on training will provide practical ‘tips and tricks’ to facilitate successful clinical assessment of ABR and ASSR. There will be time for questions and discussion of clinical cases.

After this workshop, the participant will:

  • be able to set up, perform and interpret two-channel ABR measurements
  • know advantages, limitations and pitfalls of ABR and ASSR measures
  • be able to recognize external interferences that might happen during AEP recordings and will have knowledge of how to solve these practical problems

Assessing Listening Effort: Pupillometry for Dummies

Adriana Zekveld

Lauren Fink

Jorn Sangers

Andreea Micula

This workshop will introduce the pupil response and its most common implementations within audiological research. A brief theoretical background on the mechanics of the pupil response and how listening effort is captured will be provided. This will be followed by a live demonstration of the acquisition of pupillometry data. This demo will consist of a speech perception task, and live measurement of the pupil dilation response to the perception of the stimuli. The resulting data will be shared with the attendees, in addition to pre-recorded data using the same task. A demonstration of the data pre-processing steps will be provided live, using scripts (probably Python) that will be provided prior to the workshop attendants. This will allow the audience to perform hands-on pre-processing of the data. The audience will then have the chance to conduct condition-averaged analyses, comparing the pupil response across different levels of noise. Subsequently, we will introduce ways to analyse the time-course of pupillometric data, such as single-trial, signal-to-signal analyses between the pupil and speech signals. This workshop is designed for anybody who is interested in conducting pupillometry research, and no previous experience is required.

Auditory Neuropathy

Paul Avan

Isabelle Rouillon

Auditory neuropathies form a whole spectrum of conditions (ANSDs) in which, according to their broadest definition, temporal processing of auditory cues is more severely affected than auditory sensitivity and frequency processing. Accordingly, cochlear micromechanics is less affected than inner-hair-cell synapses with cochlear neurons or action-potential conduction along auditory pathways. Obviously, whether ANSD is pre- or postsynaptic suggests different interventions with different goals. Accurate diagnosis and the identification of the mechanisms at play are indispensable for ensuring optimal intervention. A complete diagnostic procedure must thus include evaluation of cochlear micromechanics; assessment of synaptic efficacy; separate evaluation of auditory-neuron subgroups (searching for hidden dysfunctions not present at low sound levels); short-term versus long-term synchrony of auditory pathways, possibly unveiling abnormal neuronal fatigability. The goal of this workshop is to show that any audiologist, equipped with otoacoustic emissions, electrocochleography, and ABRs can easily adjust their use to characterize each ANSD pattern.

Getting the First-Fit Right: Important Insights from Binaural Broadband Loudness Perception

Dirk Oetting

Sven Winkler

In his doctoral thesis, Dirk Oetting made a ground-breaking discovery, revealing significant variations in the loudness perception of binaural broadband signals among individuals with similar audiograms. Oetting developed the « trueLOUDNESS » first-fit gain calculation method, incorporating both the hearing threshold and binaural broadband loudness summation. Since 2023, this pioneering procedure has been available for fitting hearing aids. Sven Winkler has two hearing aid shops. They changed the first fit procedure completely to trueLOUDNESS. Winkler will discuss the transformative impact of trueLOUDNESS on himself, his staff, and the overall experience and outcomes for their customers.”

How to Assess Vestibular Function in Children from A to Z ?

Sylvette Wiener-Vacher

Audrey Maudoux

Yohan Ejzenberg

Pierre Reynard

The aim of this workshop is to provide a framework for performing a complete vestibular assessment in children of all ages, starting with the clinical examination. A video will illustrate the various stages of the clinical examination in a 5-month-old baby and an 8-year-old child. This video has been widely used to illustrate the various components of the exam to both parents and children before their participation. A practical session will follow, providing training on each of the various elements of the clinical examination in the child. We will then go over the VHIT with distance camera, the bithermal caloric test, and the cervical and ocular VEMP. We will provide insights as to common challenges encountered in testing the pediatric population, as well as strategies for approach these challenges and ensuring the reliability of results.

Objective Assessment of Infant Hearing

James W. Hall III

This workshop provides audiologists with practical « take home » information on objective auditory assessment of infants. Attendees will be introduced to a protocol for the diagnosis of infant hearing loss with a test battery consisting of aural immittance measures (tympanometry and acoustic reflexes), otoacoustic emissions (OAEs), auditory brainstem response (ABR). The workshop will include hands-on demonstrations using clinical devices.

The workshop will cover the following topics

  • Introduction, Overview, Objectives, Format
  • Review of crosscheck principle in pediatric hearing assessment
  • Test protocols for objective auditory assessment
    • DPOAEs
    • Aural immittance measurements
    • ABR
  • Hands-on demonstration: DPOAE measurement and analysis
  • Hands-on demonstration: Aural immittance measurement and analysis
  • Hands-on demonstration: Neurodiagnostic and threshold estimation ABR
  • measurement and analysis including:
    • Air conduction click ABR measurement and analysis.
    • Bone conduction click ABR measurement and analysis.
    • Tone burst ABR measurement and analysis.

Hearing evaluation in the clinic – when & how to test auditory processing

Doris Eva Bamiou

Helen Grech

Vasiliki Maria Iliadou

Hung Thai Van

The recent WHO Report on Hearing (2021) highlighted that pure tone audiometry, despite being considered as the gold standard for hearing evaluation, does not provide the best insight of hearing capacity in everyday life situations.

A more real-life assessment of hearing capacity would be a speech-in-competition (noise/babble/other speech) test, that is a key component of auditory processing evaluation in global guidelines. In the same perspective, the assessment of dichotic skills is also essential.

Join this workshop to learn:

  • when to consider auditory processing evaluation
  • which tests to include and why

Learning objectives will be accomplished with short theoretical lectures, practical demonstration of different tests (both established and emerging) and interactive case studies presentation that will provide you with a basis for setting up your up-to-date clinical practice.

Auditory training approaches in children with listening difficulties and in adults with cochlear implants

John Galvin

Dave Moore

As is often said, it is the brain that hears, not the ear. The brain must make sense of natural and electric stimulation patterns. Depending on age, the trajectory for learning auditory stimulation can be quite different. For example, using cochlear implants (CIs), prelingually deaf children develop auditory perception entirely with novel stimulation, similarly to most normally hearing children. Postlingually deaf or hard of hearing adults adapt to new auditory patterns relative to their previous experience with acoustic hearing. Attempts to train children using computer-based training have largely failed, but recent, remote microphone hearing aids and child-oriented enhanced communication techniques have been more promising. While most CI recipients “passively” adapt to electric stimulation (typically over 6-12 months), “active” auditory training can further improve auditory perception, even for experienced cochlear implant users. Drs. David Moore and John Galvin will discuss different auditory training approaches and outcomes for children and adults, respectively

HINTS ++ for an accurate diagnosis in current peripheral vestibular disorders

Eugen Ionescu

Luigi Califano

Leonardo Manzari

Peripheral or central » is the question that any doctor asks in front of a patient who comes to the emergency room for acute vertigo or dizziness. Besides a detailed history regarding onset, the HINTS examination is a basic tool in the detection of acute central causes, including posterior circulation strokes. The acronym refers to HI: Head Impulse, N: Nystagmus direction and TS: Testing Skew and was introduced in 2009 by Kettah et al. The same authors proposed in 2013 that « HINTS plus Hearing » or « HINTS+ » could improve diagnostic sensitivity. In this workshop, the authors propose not only an exposition with examples of the basics of this exam, but also the upgrade of HINTS+ to HINTS++. This being a mixture of the above method with other tricks that instructors use in the initial and follow-up vestibular exam that allows them to specifically target the diagnosis to certain peripheral vestibular pathologies.
