Advanced topics in hearing research
DTU Department of Health Technology
The course aims to develop students’ independent learning skills and increase their awareness of recent literature within their research areas and related fields. It also seeks to strengthen students’ scientific communication skills and to promote timely discussion of emerging and high-impact topics in the field.
Learning objectives:
A student who has met the objectives of the course will be able to:
- Present, critically discuss, and evaluate recent “hot-topic” journal publications in hearing science and technology.
- Present and critically assess contemporary concepts in auditory modeling.
- Explain the perceptual consequences of different types of hearing impairment.
- Characterize state-of-the-art experimental methods for measuring auditory perception.
- Discuss the capabilities and limitations of objective measures of auditory function, including otoacoustic emissions, auditory evoked potentials, and functional magnetic resonance imaging (fMRI).
- Evaluate neural coding principles and compensation strategies implemented in modern hearing aids and cochlear implants.
- Explain the roles of audibility, frequency selectivity, and temporal processing in speech and melody recognition under both quiet and adverse listening conditions.
- Discuss mechanisms of audio-visual integration in speech perception.
- Critically evaluate recent machine-learning–based approaches to auditory data analysis, signal processing, modeling, and hearing-loss compensation.
- Relate current research topics to collaborative clinical themes in audiology, including translational research activities conducted in partnership with the Copenhagen Hearing and Balance Center (CHBC) at Rigshospitalet.
Contents:
The course addresses recent and emerging concepts in theoretical, experimental, and translational hearing research. Topics include: - Computational, physiologically inspired, and data-driven models of auditory processing - Cochlear mechanics and cochlear signal transformation - Recording techniques and physiological generation mechanisms of auditory evoked potentials and otoacoustic emissions - Objective measures of auditory function and their relation to psychoacoustical (behavioral) findings - Perceptual and neural consequences of hearing impairment - Speech perception, signal detection, and auditory scene analysis in complex acoustic environments - Neural coding principles and central correlates of auditory perception - Machine-learning–based approaches to auditory data analysis, modeling, signal processing, and hearing-loss compensation - Principles of spatial and binaural hearing - Signal processing strategies in modern hearing aids and cochlear implants - Current translational and clinical research themes in audiology, including collaborative activities with the Copenhagen Hearing and Balance Center (CHBC) at Rigshospitalet Each student will give two oral presentations over the course of the year. One presentation will critically summarize and evaluate the objectives, methods, and key findings of a selected recent publication from a high-impact scientific journal, with particular emphasis on its implications for future research and clinical practice. The second presentation will focus on the student’s own PhD research project and closely related research directions, fostering interdisciplinary discussion, critical reflection, and scientific feedback within the group.
