The Hearing Systems Section at the Technical University of Denmark (DTU) seeks a qualified candidate for a 3-year PhD position. Hearing Systems is part of the department of Health Technology. Our research is concerned with auditory signal processing and perception, speech communication, audiology, behavioural and objective measures of auditory function, computational auditory neuroscience, environmental acoustics, and hearing-instrument signal processing. The goal of this research is to understand the functioning of the human auditory system and to provide insights that are useful for technical applications, such as speech recognition systems, hearing aids, cochlear implants, and hearing diagnostics.
The project will focus on communication and interaction in adverse acoustic conditions. The goal is to characterize how various objective measures of interactive behaviour and speech production are influenced by the acoustic environment and hearing loss. An additional goal is to explore the benefit of hearing aids in making the dynamics of conversations involving aided hearing-impaired listeners more like those between normal-hearing listeners. The interaction between participants will be investigated by monitoring motion behavior and examining changes in head orientation, eye gaze, distance, etc. Furthermore, features of the speech signal, such as vocal effort or the temporal patterns in turn-taking behavior may also carry information about the level of difficulty involved in a given interaction. By monitoring listener behaviour while varying the complexity of the acoustic scene, the various strategies used by humans to maintain communication in adverse conditions can be characterized as a function of scene complexity, such as signal-to-noise ratio (SNR), the number of sources, reverberation, movement, etc. This will allow to determine markers that correspond to different listening goals and markers of increased listening/communication effort. In particular, the limits where communication breaks down could be identified in terms of the scene complexity, hearing impairment, and hearing-aid processing strategies.
The project is part of the Centre for Applied Hearing Research (CAHR) supported by Oticon, WSA and GN Hearing. This PhD project represents one of thee CAHR research streams with a variety of connection points which are intended to foster collaborations and common subprojects across the three research streams.
Responsibilities and qualifications
You will work with behavioural and physiological measures to evaluate the consequences of hearing loss on the processing of simple and complex sounds, including speech. You will work with computational models of auditory signal processing and perception. You will also explore effects of hearing-aid signal processing strategies on both behavioural and outcome measures and evoked potential patterns.
You should be well-versed in some scientific programming environment (MATLAB, Octave, SciPy) and should have knowledge of signal processing and experimental design.
You must have a two-year master’s degree (120 ECTS points) or a similar degree with an academic level equivalent to a two-year master’s degree.
Approval and Enrolment
The scholarship for the PhD degree is subject to academic approval, and the candidate will be enrolled in one of the general degree programmes at DTU. For information about our enrolment requirements and the general planning of the PhD study programme, please see the DTU PhD Guide.
The assessment of the applicants will be made by Associate Professor Tobias May and Professor Torsten Dau.
DTU is a leading technical university globally recognized for the excellence of its research, education, innovation and scientific advice.
