Professionals in the fields of audiology, electrophysiology of hearing, and hearing technology from all over the world will present their cutting edge research. There will be insightful lectures by prestigious invited speakers and opportunities to network with colleagues regarding the future of our field. Busan is a port city located in the southern part of Korea with many beaches and a variety of exotic sightseeing. Our symposium will be held at Haeundae beach which is the most famous and beautiful beach in Korea. We will also have an outing to the nearby ancient capital of Gyeongju with its rich heritage and cultural treasures. We are sure these will help you relax and create some great memories with colleagues while you are here. On behalf of the IERASG Organizing Committee, I am pleased to invite you to participate in this wonderful meeting. With your great enthusiasm and contributions, we are confident that this meeting will be very productive, beneficial and enjoyable for you. We look forward to seeing you in Busan at IERASG 2015! Best wishes, Lee-Suk Kim, M.D., Ph.D. Chair of the Organizing Committee, IERASG 2015 3 IERASG 2015 Welcome Message It is my privilege and honor to join Professors Lee-Suk Kim and Jun Ho Lee and others of their organizing committee to the beautiful venue of Busan for this, the XXIV Biennial Symposium of the International Evoked Response Study Group. Attendees and others ultimately reading this Welcome who are new to the IERASG and those who have not attended an IERASG symposium previously can find more information, including abstracts of past programs, on our home website: www.ierasg.ifps.org.pl I shall not endeavor to summarize (in good part in fear of not doing it justice) the long history of our society. We have enjoyed informality as a key to success for what seems to have resonated with attendees over the decades. At the same time, we have been able to involve numerous leaders in the field of Electric Response Audiometry and related areas, and then younger researchers and clinicians who subsequently have become leaders. That IERASG informality is expressed in keeping organization to a minimum, but most critically in the “tone” of our meetings. Our IERASG meetings are first and foremost intended to bring participants, whatever their level of contribution to the meeting, whatever their professional identity, and at whatever career level (namely from students on) together in a meeting that readily permits interactions without ‘standing on ceremony’. Our meetings are to encourage exchanges fully across disciplines and sub-disciplines, hence our aversion for parallel sessions. Social events are intended to be extensions of the scientific program, in the sense of “working and playing” together in what we fondly call meetings of Hal’s Club (started by Professor Hallowell Davis in 1968). The word “club” here does not have the usual connotations (we do not even have a secret handshake, nor, on the other side of possible meanings, do we play deafening music at social events). Rather, the reference is one of building interactions without perceived boundaries—thus openness—with the hope of better mutual understanding of our respective works and perhaps leading sooner or later to collaborations. Many past and present attendees look back to the Biennial Symposia as having somehow seeded some of their most enduring professional relationships, especially globally. My personal first Biennial Symposium was in 1977 in Jerusalem. At the time, I had barely put a dent in seeing even Western Europe, coming from a small farming community in Southeastern Ohio, and there found myself in one of the most iconic cities in the world, not only to visit ancient sites but to talk about one higher passion--auditory neurophysiology--with like-minded scholars from around the world. 4 XXIV Biennial Symposium of International Evoked Response Audiometry Study Group I shall only say a brief word about the science, per se, as we deal with numerous and diversity topics ultimately up and down the “ERA family tree”, but, the 2015 program speaks well to this, and together with glancing over past programs (documented in part on our website) shows well the waxing-and-waning of interests. Often much emphasis is placed on what’s new/novel, as should be compelling of our attention, and certainly pushing the ERA boundaries is a priority for our meetings. The publish-or-perish environment in which some of us work proves not to necessarily follow the scientific method, or at least is weak on one important element—that of verifying results through repeated observations in order to fully establish scientific laws. Hence, looking yet again at “old” ERA approaches can be worthwhile. There then is the even more time-consuming process of sorting out details of theory-versus-methods that actually work in the clinic. Indeed, there is inevitably the element of reinvention of the wheel, but various “wheels” in ERA related areas well have needed reinvention. It also is amazing how some issues seem to never have been settled or, if accepted, still have not been established based on rigorous scientific work, let alone evidence-based practice. We thus put no bounds on our loosely defined central theme for the IERASG meetings and welcome both new and continued discussion in search for ultimate ERA truths. Our meetings have embraced all of these elements, decade after decade, and can be expected to serve such needs well into the future. My final words of welcome are by way of a footnote to current efforts by the nominally “governing body” of the IERASG—the Council—to both reflect and consider the past versus future of the organization. Last year, we initiated an “off-year” activity to help keep the IERASG name out there, namely a special session of the World Congress of Audiology in Brisbane. For this year’s Biennial Symposium, we have expanded the meeting to use the registration and welcome day more substantively by way of offering a couple of workshops. In the business meetings of the Council, also conducted during the symposium, we will be working diligently to carry on “Club” business, considering bids for up-coming symposia as usual and looking beyond to how best to preserve the IERASG for future students and established workers alike. On behalf of the Council, I thus thank you for your contribution to this Biennial Symposium, representing our second meeting in Asia, and with the hope that you will find this meeting of the minds and culture to be strong incentive for your future participation. I thus wish you a warm welcome to this Biennial Symposium and the gracious hospitality of our hosts. John D.

Once a failure in decoding information has been detected, an evaluation can be performed by auditory evoked potential as FFR. Material and Methods: 60 children and adolescents aged 8 to 14 years were included in the study. The subjects were assigned into two groups: a control group (CG) consisted of 30 typically developing children with normal hearing; and an experimental group (EG) of 30 children, also with normal hearing at the time of assessment, but who had a history of secretory otitis media in their first 6 years of life and who had under- gone myringotomy with placement of bilateral ventilation tubes.

  • The Effect of Higher Order Listening Function and Hearing Loss on Cognition
    THE EFFECT OF HIGHER ORDER LISTENING FUNCTION AND HEARING LOSS ON COGNITION IN OLDER ADULTS GRACE KELLEE NIXON ORCID 0000-0002-4106-6554 Submitted in total fulfilment of the requirements of the degree of Doctor of Philosophy January 2020 Department of Audiology and Speech Pathology The University of Melbourne i ii © 2020 GRACE KELLEE NIXON ALL RIGHTS RESERVED iii iv ABSTRACT Grace Kellee Nixon: The Effect of Higher Order Listening Function and Hearing Loss on Cognition in Older Adults INTRODUCTION: Previous research has identified a relationship between hearing loss and cognitive impairment/dementia in older adults, however this research has primarily focused on measures of sensorineural hearing loss (SNHL). Central Auditory Processing (CAP), an ability which decreases with increasing age, is recognised as important for understanding speech in background noise, but is not routinely considered in audiological assessment or hearing-cognition research. Yet, some studies have provided evidence that poorer performance on some measures of CAP ability significantly relate to reduced cognitive function and/or increased likelihood of dementia diagnosis. Although there is no known treatment for cognitive impairment, hearing impairment is to some extent treatable with hearing aids (HAs). OBJECTIVES: This study aimed to examine the relationship between hearing impairment and cognitive impairment by assessing both peripheral hearing loss and CAP ability. Additionally, this research aimed to investigate how hearing, cognition and personal factors influence HA outcomes (uptake/use/benefit) in older adults. DESIGN: Experimental study design with 85 older adults between the ages of 60.33 and 80.08 (m =70.23, SD = 5.17). SNHL was assessed using Pure Tone Audiometry (PTA), the Listening in Spatialised noise-Sentences (LiSN-S) test and Dichotic Digits Test.

  • Gidado Jennifer Busayo 18/Mhs01/166 Nursing Physiology
    GIDADO JENNIFER BUSAYO 18/MHS01/166 NURSING PHYSIOLOGY Discuss the physiology of balance The vestibular system is the sensory apparatus of the inner ear that helps the body maintain its postural equilibrium. The information furnished by the vestibular system is also essential for coordinating the position of the head and the movement of the eyes. There are two sets of end organs in the inner ear, or labyrinth: the semicircular canals, which respond to rotational movements (angular acceleration); and the utricle and saccule within the vestibule, which respond to changes in the position of the head with respect to gravity (linear acceleration). The information these organs deliver is proprioceptive in character, dealing with events within the body itself, rather than exteroceptive, dealing with events outside the body, as in the case of the responses of the cochlea to sound. Functionally these organs are closely related to the cerebellum and to the reflex centres of the spinal cord and brainstem that govern the movements of the eyes, neck, and limbs. Although the vestibular organs and the cochlea are derived embryologically from the same formation, the otic vesicle, their association in the inner ear seems to be a matter more of convenience than of necessity. From both the developmental and the structural point of view, the kinship of the vestibular organs with the lateral line system of the fish is readily apparent. The lateral line system is made up of a series of small sense organs located in the skin of the head and along the sides of the body of fishes.

OAE types have traditionally been categorized by the stimulus/stimuli used to evoke them. However, more recent work suggests that there are two distinct classes of OAEs – distortion (nonlinear) and reflection (linear). It is theorized that emissions within a respective class share a common generation mechanism. While distortion emissions are thought to arise from nonlinear processes associated with outer hair cell transduction, reflection emissions are thought to arise from the back-scattering of energy due to irregularities, or “roughness”, along the cochlear partition. In this project, we explore two types of OAEs evoked using different stimuli but theorized to both be reflection-type emissions: stimulus-frequency OAEs (SFOAE) and the reflection component of distortion product OAEs (DPOAER).

Lamminen, Daniel Houlihan Minnesota State University, Mankato, USA Email: [email protected] Received 29 April 2015; accepted 2 August 2015; published 5 August 2015 Copyright © 2015 by authors and Scientific Research Publishing Inc. This work is licensed under the Creative Commons Attribution International License (CC BY). http://creativecommons.org/licenses/by/4.0/ Abstract Amblyaudia, a recent subcategory of auditory processing disorder, is characterized by asymme- trical auditory processing of an individual’s ears. Amblyaudia can result in speech comprehension difficulties, reading difficulties, information processing deficits, and inattention. These difficulties can be mistakenly attributed to Attention Deficit Hyperactivity Disorder (ADHD), Specific Learning Disorders (SLD), depression, anxiety disorders, and communication disorders. Unfortunately, tra- ditional hearing tests do not place the two ears in competition and cannot detect asymmetry. Therefore, students who exhibit these difficulties and have normal performance on traditional hearing tests should be also evaluated for amblyaudia with dichotic listening tests. Amblyaudia can be addressed through dichotic listening tasks that strengthen the non-dominant ear, as well as minor adjustments to the classroom environment. This paper will examine the current literature on amblyaudia and provide a brief overview of the causes, diagnosis, treatments, and prognosis. Keywords Amblyaudia, Auditory Processing Disorder, Otitis Media 1. Introduction Amblyaudia is a new diagnostic category within Auditory Processing Disorders (APD) [1] [2]. When one ear is developmentally deprived it causes the other ear to compensate and leads to weaknesses in the listener’s binau- ral processing of auditory information [2]-[4].
