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.

Despite the possibility of advanced signal processing strategies, hearing aids typically provide only moderate noise reduction and slow-acting dynamic range compression to avoid the amplification of artefacts. In this project, new hearing-aid signal processing strategies are investigated. It is hypothesized that a hearing aid should ideally (i) provide fast-acting dynamic range compression to the signal of interest (the “foreground”), (ii) prevent amplification of artefacts that were introduced by the preprocessing and (iii) maintain the naturalness of the “background” by applying slow-acting dynamic range compression. The different processing of foreground vs background is here referred to as “scene-aware” hearing-aid processing.

Responsibilities and tasks
You will work with signal processing and machine learning concepts, will explore hearing-aid signal processing strategies and use behavioral tests to evaluate the consequences of hearing-aid processing in simulated real-world conditions.

You should be well-versed in some scientific programming environment (MATLAB, Octave, SciPy) and should have knowledge of signal processing and experimental design.

The project will be conducted in collaboration with the hearing-aid company Sonova, located in Switzerland. You will therefore have regular contact and interaction with a scientific supervisor from their side and visits to Sonova can be expected throughout the course of your study.  

Qualifications
Candidates should 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

Assessment
The assessment of the applicants will be made by Prof. Torsten Dau and Assist. Prof. Tobias May.
