About Hearing Systems

Hearing Systems educates engineers within the fields of speech and hearing science and communication acoustics at BSc, MSc and PhD levels.The research in hearing systems focuses on auditory and speech processing and perception, functional models of hearing, audiology, physiological acoustics, objective measures of hearing and hearing instrument signal processing.

Together with Acoustic Technology we offer the international MSc programme Engineering Acoustics.

Hearing Systems consists of the two centres:
Centre for Applied Hearing Research,CAHR, and Oticon Centre of Excellence for Hearing and Speech Sciensces,CHeSS and is part of several collaborative projects.


Centre for Applied Hearing Research 
is a centre at DTU Electrical Engineering with the purpose of promoting research and education within the field of acoustic communication with emphasis on:

Signal processing principles in the human auditory system

  • Perceptual consequences of hearing impairment
  • Functional models of auditory processing and perception
  • Applications of auditory models in hearing instruments
  • Measurement and diagnosis of auditory function
  • Technical audiology and Speech perception

The centre is supported by three the Danish hearing-aid companies Oticon, Widex, GN Resound, and their foundations. In addition Phonak and Siemens have been supporting individual PhD projects within audiology and hearing technology.


Oticon Centre of Excellence for Hearing and Speech Sciences
Another research centre has been founded under the leadership of Professor Torsten Dau in parallel with CAHR. While CAHR focuses on more applied research Oticon Centre of Excellence for Hearing and Speech Science, CHeSS, has more focus on fundamental research.
CHeSS has a special focus on cross-disciplinary basic research in the audiological disciplines.
The different disciplines will investigate the codes of the human auditory system. The centre also includes a large new laboratory, an Audio Visual Immersion Lab (AVIL). Through a special technology the sound impressions will be reproduced and combined with visual images.
Oticon Centre of Excellence for Hearing and Speech Sciences has employed a considerable number of scientists, visiting professors, postdocs and PhD students, who work together on a number of carefully selected basic research projects in the field of audiology.
In addition to internal cooperative partners and experts based at DTU, external experts from educational institutions such as Université Paris Descartes in France, University of California, Berkeley, in the USA and Danish Research Centre for Magnetic Resonance, Hvidovre Hospital, is involved to a great extent. CAHR will at the same time start a number of applied research projects supported by the Danish hearing-aid industry. 

Cognitive Control of a Hearing Aid Horizon 2020
The Cognitive Control of a Hearing Aid (COCOHA) Horizon 2020 project has the ambitious aim of creating a hearing-aid system that can be mentally (cognitively) steered by the user. Advanced signal processing techniques, such as beamforming and source separation, have the potential of isolating and enhancing individual sound sources in a complex acoustic environment. However, selecting which source to enhance presents a major challenge. In this project, methods and algorithms will be developed to decode brain signals picked up by EEG electrodes, and to extract attention and intention signals, matching them to acoustic sources in the environment.

Better Hearing Rehabilitation Project

A new, large collaborative project between the University of Southern Denmark, Aalborg University, the Technical University of Denmark (Hearing Systems, Elektro) independent tech company DELTA, Danish hearing aid manufacturers Oticon, Widex and GN Resound and the university hospitals in Odense, Aalborg and Copenhagen will improve quality of hearing care so that people with hearing loss can benefit more from their hearing aids.

TIN-ACT: Tinnitus Assessment, Causes and Treatments
Tinnitus (“ringing in the ears”) is a very common and potentially devastating condition. People with tinnitus continuously hear a penetrating phantom sound in absence of actual sound. Even mild forms of tinnitus reduce productivity due to difficulty hearing and concentrating at work and also resting and relaxing during leisure time. In order to cure tinnitus, we need to bridge the gap between basic fundamental research, applied clinical research and product development. Our aim is to understand how complementary research techniques can be used towards curing tinnitus.

Uncovering hidden hearing loss

Supported by the Novo Nordisk Foundation, a new interdisciplinary synergy project “Uncovering hidden hearing loss” (UHEAL) will combine magnetic resonance imaging technology with audiology and neurophysiology to establish methods for measuring this nerve damage in humans. The project will be carried out in close collaboration with Hartwig Siebner and colleagues from the
Danish Research Centre for Magnetic Resonance and Charles Liberman from Harvard Medical School.
