Management of Hearing Loss and Hearing Disorders in The Music Industry

For Music Industry Professionals, Music-Induced Hearing Loss (MIHL) and Music-Induced Hearing Disorders (MIHD) can devastate both the vocations and the identities of the affected individuals. Beyond facing potential economic hardship from lost employment, affected individuals may also face mental health challenges as they “re-learn” how to play their most valuable instrument: their own hearing. For some, hearing aids may successfully reconnect them with their industry, but often,alternative amplification must be utilized. For those struggling with MIHD, management strategies, counseling, and amplification, at the least, should be considered, both in relation to personal communication with others and also in relation to their professional life immersed in sound. As many individuals in this industry are exposed to hazardous noise levels, protecting their hearing remains paramount. This presentation will focus on the practical applications of amplification, disorder management, and counseling as they relate to working on, behind, or off-stage for Music Industry Professionals. Specifically, alternative amplification and management strategies will be discussed, along with a case study of diplacusis.

Bringing the real world into the lab: Hearing research in interactive virtual environments

The understanding of auditory cognitive processes and abilities, ranging from perception, attention, and memory to complex performances such as scene analysis and communication, has advanced considerably in recent years. To this end, well-controlled but often unrealistic stimulus presentations have been used. These have included simple instances of virtual environments. Audiovisual Virtual Reality (VR) has reached a high level of perceptual plausibility, overcoming some of the limitations of simple laboratory settings, with recent developments in hardware and software technologies. Interactive auditory VR is now available and even applicable to non-specialized labs, where humans can interact with the auditory scene. This allows for real-time adaptation of complex auditory input to the listener's ears. The increased use of such interactive VR technology in laboratory settings is expected to contribute to the understanding of auditory perception in complex audiovisual scenes that are closer to real life, including acoustically challenging situations such as classrooms, open-plan offices, noisy multi-talker communication, and outdoor scenarios. However, understanding the extent to which classical theories of auditory cognition and related empirical findings are applicable within representative interactive audiovisual VR is an important consideration in bringing real life into the laboratory. This talk will present recent examples of research currently being conducted by the Institute of Hearing Technology and Acoustics (IHTA) at RWTH Aachen University. A particular focus is on our studies of activity-based acoustic situations in primary schools, where we analyze classroom noise, attention, and listening effort using audiovisual VR methods. These advances will be discussed in relation to the future of interdisciplinary approaches that combine auditory perception and processing and audiovisual VR in the study of hearing.

Symposia

Beginning in 2010 with a symposium in honor of Peter Dallos, the Knowles Hearing Center has held an annual full‐day symposium every fall. 

The symposium was conceived to attract an audience of researchers and clinicians that extends well beyond the Northwestern University academic community. A new topic is chosen each year by our Fellows in order to appeal to top investigators and clinicians worldwide. While our seminars are designed to introduce one scholar’s ideas to our community, our symposia are designed to showcase a particular topic that is critical to holistic hearing health.

Understanding Reduced Sound Tolerance: Definitions, Diagnosis, and Management

Abstract: Reduced sound tolerance is a pathological condition for which tolerance to sounds is so reduced that normal tolerable everyday sounds induce discomfort. This general term encompasses different forms of reactions and responses to sounds including hypersensitivity to loud sounds (loudness hyperacusis), sound-triggering pain (pain hyperacusis) and aversion to specific sounds (misophonia). According to epidemiological studies, around 10 to 15% of the general population suffers from these disorders. They can greatly affect the quality of life, and the socio-economic integration of individuals affected. During this presentation, an overview of the different forms of reduced sound tolerance will be described and discussed. An up-to-date review of the current diagnostic methods will be presented. Finally, the state of knowledge regarding current and future therapeutic options will be briefly discussed.

Bio: Dr. Fournier is an Assistant Professor of Audiology at Université Laval, a clinical audiologist and a Researcher at the Centre interdisciplinaire de recherche en réadaptation et intégration sociale (CIRRIS) in Québec City. His research is dedicated to exploring a spectrum of auditory pathologies, encompassing tinnitus, hyperacusis, misophonia, and acoustic shock syndrome. Driven by a passion for unraveling the intricate workings of these conditions, his research endeavors focus on elucidating the underlying pathophysiological mechanisms, pioneering novel diagnostic methodologies, and advancing patient care through the implementation of cutting-edge therapeutic interventions.

Misophonia: New Disorder at the Intersection of Hearing and Mental Health?

Abstract: Misophonia is characterized by strong negative multi-modal responses to specific sounds and associated stimuli commonly produced by others, repetitive, and oral or facial in origin (e.g., chewing, crunching, eating, drinking, throat-clearing, coughing, breathing, etc.). Patterns of reactions may be attentional (e.g., hypervigilance toward possible sound stimuli), physiological (e.g., increased sympathetic nervous system activation including increased heart rate and sweating), affective (e.g., the subjective experience of feeling a sudden increase in anger, rage, disgust, anxiety, and other unpleasant affective states), cognitive (e.g., dysfunctional assumptions, beliefs, rules, and other cognitions such that may include internal and/or external attributions), behavioral (e.g., avoidance, escape, distraction), and/or interpersonal (e.g., confrontation, indirect aggression, withdrawal, demands). First introduced in 2001, Misophonia is being rapidly studied, has been defined by expert consensus, and appears to be differentiable from existing audiologic and mental health diagnoses. This presentation will (a) review the latest scientific literature investigating misophonia, (b) outline evidence supporting it as a unique and new diagnostic category, and (c) raise the question of whether to classify this new disorder within the mental health or audiologic nomenclature.

Bio: Dr. Zachary Rosenthal is a clinical psychologist and Associate Professor with a joint appointment in the Department of Psychiatry & Behavioral Sciences and Department of Psychology & Neuroscience at Duke University. He is Director of the Duke Center for Misophonia and Emotion Regulation (CMER), leading a team conducting research, providing education, and developing clinical care pathways for Misophonia. He also directs the Duke Cognitive Behavioral Research and Treatment Program and is Co-Chief Psychologist for the Department of Psychiatry & Behavioral Sciences.

Towards mechanistic models of misophonia

Abstract: Misophonia is a disorder of decreased tolerance to specific, every sounds that are not problematic for most people. These sounds, known as "triggers", are experienced as unpleasant or distressing and tend to evoke strong negative emotional, physiological, and behavioral responses and can significantly affect quality of life. Recent research has made some progress towards differentiating the disorder from other types of sound sensitivity, and documenting behavioral, physiological and neurological differences between people who suffer from misophonia and healthy controls. However, we lack a unifying theory about its neurobiological basis. In this talk, I will outline current ideas concerning the neural circuitry that might give rise to misophonia, with a view towards developing models that yield testable hypotheses and predictions.

Bio: Dr. Emily Coffey is a cognitive neuroscientist known for her research on auditory perception, learning, and brain plasticity. She focuses on top-down and attentional processes in misophonia and has begun to synthesize this into neurobiological models of misophonia.

A dimensional framework to shine light on the dark side of audition

Abstract: Dr. Chandrasekaran, an auditory cognitive neuroscientist, employs a systems neuroscience approach to explore the neurobiology of auditory categorization and learning. In this presentation, he shares his personal experience with misophonia, advocating for the field to shift from monolithic diagnostic labels to a dimensional framework grounded in systems neuroscience. This approach addresses the challenges of individual variability, heterogeneity, and co-morbidity in auditory disorders.

Bio: Dr. Chandrasekaran is the Ralph and Jean Sundin Endowed Professor and Chair of the Roxelyn and Richard Pepper Department of Communication Sciences and Disorders. His research program employs a systems neuroscience approach to investigate the computations, maturational constraints, and plasticity underlying auditory signals such as speech and music. Over the past two decades, his lab has utilized cutting-edge behavioral, multimodal neuroimaging, and modeling-based approaches to achieve a computational, algorithmic, and implementation-level understanding of how sounds are represented and mapped to behaviorally relevant constructs in the human brain. From a clinical perspective, the SoundBrain Lab hopes to enrich our understanding of the neurocognitive sources of individual differences in speech processing and to develop neurobiologically-informed auditory training protocols for learning impairments and auditory processing deficits.

Sound Sensitivity Disorders: New Perspectives on Mechanisms and Biomarkers

Abstract: Sound is jointly processed along acoustic and emotional dimensions. These dimensions can become distorted and entangled in persons with sensory disorders, producing a spectrum of loudness hypersensitivity, phantom percepts, and – in some cases – debilitating sound aversion. In human subjects, we recently described new approaches to study affective sound processing (doi.org/10.1101/2023.12.22.571929). We found that pupil dilations and facial movement amplitudes scaled with sound valence in neurotypical listeners but not in participants with chronic tinnitus and sound sensitivity. In these participants, emotionally evocative sounds elicited abnormally large pupil dilations but blunted, invariant facial reactions that jointly provided an accurate prediction of individual tinnitus and hyperacusis questionnaire handicap scores. By contrast, EEG measures revealed steeper neural response growth functions but no association with symptom severity. These findings suggested that neural hyper-responsivity, hyperactivity, and hyper-synchrony in central auditory networks can impart disordered sound processing in limbic and autonomic networks that regulate auditory valence and arousal. We have tested this idea in animal models, where we can isolate neural defects underlying loudness hypersensitivity and disordered affective sound processing by recording from genetically targeted cell types in the mouse auditory cortex and lateral amygdala. We recently found that parvalbumin-expressing inhibitory neurons (PVNs) in the mouse auditory cortex provide a volume knob for the perception of loudness, where targeted activation or inactivation of PVNs shifted loudness reporting by +/- 20 dB (doi.org/10.1101/2024.05.30.596691). After noise-induced sensorineural damage in the high-frequency region of the cochlea, mice reported loudness hypersensitivity for spared, mid-frequency sounds and neural hyper-responsivity in the auditory cortex and amygdala. Importantly, activating PVNs in hyperacusic mice completely restored normal loudness perception, even though sensorineural damage in the ear remained untreated. For example, several minutes of PVN stimulation at 40Hz reversed loudness hypersensitivity for up to a week, underscoring the promise of therapies for sound sensitivity disorders that focus on higher stages of the central auditory pathway.

Bio: Dr. Polley is Professor of Otolaryngology – Head and Neck Surgery where he serves as the Director of the Eaton-Peabody Laboratories, Director of the Lauer Tinnitus Research Center, and Vice Chair for Basic Research in the Department of Otolaryngology─Head and Neck Surgery. Dr. Polley's research focuses on experience-dependent brain plasticity and its therapeutic applications for hearing loss, sound sensitivity and tinnitus. Specifically, he studies 1) the effects of hearing loss on the central nervous system, 2) the influence of learning and emotion on the neural processing of sound, and 3) new modes of therapy and rehabilitation for chronic tinnitus and auditory hypersensitivity.

Maladaptive learning may contribute to negative responses to sound

Abstract: Chronic pain has been proposed to arise, in part, from maladaptive learning. Here we introduce a potential process by which maladaptive learning may contribute to the escalation of negative responses to sound. We have observed that training on auditory perceptual tasks is particularly effective when periods of task performance (attention directed to the sounds) are combined with periods of stimulus exposure alone (attention directed away from the sounds). However, while this combination can have a robust positive influence on sound perception, it could have a negative influence as well. For example, a person with annoying tinnitus may periodically attend to it--like repeatedly pressing on a bruise to see if it still hurts. The attention may enhance the annoyance on its own, but the continuation of the tinnitus even when the person's attention is elsewhere, could supercharge it. If so, negative responses to a sound could potentially be diminished by reducing the number of periods in which attention with a negative valence is focused on the sound, so as not to feed the negative responses through unattended exposures to the sound. We have also observed that auditory learning can be disrupted when periods of auditory task performance are combined with periods of stimulus exposure alone, if the stimulus exposures are presented during performance of an attention-demanding visual task. This outcome provides another potential route for reducing maladaptive learning that may contribute to negative responses to sound.

Bio: Dr. Wright is Professor of Communication Sciences and Disorders. Her research interests include auditory perceptual learning and attention. She studies these topics primarily in young adults with normal hearing, but also in children, adolescents, and older adults, as well as in people with atypical sensory experience (hearing loss) and cognitive background (language and reading disorders).

Misophonia: from personal experience to scientific inquiry

Abstract: In this talk, I will describe how my experiences as a sufferer of misophonia have motivated and informed my research into its neurological bases. I will discuss how the lack of understanding and resources available on the topic have led me to pursue this research path and give personal insights into the challenges and benefits of being a misophonia researcher with misophonia. I will also explain how our lab is actively working to address these gaps by developing tools and making behavioral, physiological, and neuroimaging data available to the broader research community. I will also provide an overview of current research projects, which focus on understanding the attentional and cognitive processes involved in misophonic responses. I will highlight my recent work on the role of voluntary attention in misophonia, examining how attentional processes can be leveraged to mitigate negative reactions to misophonia trigger sounds.

Bio: Ms. Savard is a third-year PhD student in the Psychology (Research) program at Concordia University, Montréal, Canada, co-supervised by Dr. Emily Coffey and Dr. Mickael Deroche. Her research, supported by the Natural Sciences and Engineering Research Council of Canada, focuses on the cognitive and neural processes underlying misophonia. Driven by her personal experience with the condition, Marie-Anick's current work examines how attentional processes affect misophonic responses, using behavioral and physiological measures to explore how these responses can be modulated through cognitive strategies.
