Quantitative modeling of subcortical auditory evoked potentials
Miguel Temboury, Research Assistant

Computational models of the human peripheral auditory system based on animal physiology have shown potential for significant progress in hearing research. The simulated peripheral responses can be translated into auditory evoked potentials - EEG responses to acoustic stimuli that are measured non-invasively. The goal of this project is to develop a modeling framework that can accurately predict evoked potentials in normal-hearing and hearing-impaired listeners, which could benefit future hearing research and diagnosis of hearing impairment.

The Effect of Hearing Loss on Sound Texture Perception

Oliver Scheuregger, Research Assistant

Sound textures offer an ecologically valid means of probing the auditory system, whose statistics are shaped by auditory processes. Previous studies have already explored perception of sound textures in normal hearing listeners, however no work has investigated how hearing impaired listeners perceive textures. This project will be a direct extension of his master's project, in which Oliver measured sound texture identification and discrimination performance in normal, impaired and aged listeners. The goal is to investigate if sound textures may be used to better understand and diagnose differences between normal hearing and hearing impaired listeners, with the ultimate goal of aiding in the development of new compensation strategies.

Integrating the visual in AVIL

Kasper Duemose Lund, Research Assistant

Kasper is working on the integration of virtual reality in the Audio Visual Immersion Lab (AVIL). As of now, the AVIL does not have any permanent setup for providing visual stimulation to subjects participating in perceptual experiments. With this HTC Vive based virtual reality implementation, researchers have the framework for exposing subjects to 3D visual environments corresponding to the played back audio environments of the AVIL. A full synchronization of the existing audio engine and the new visual integration will be included. Audio-visual scenarios can therefore be presented in a highly controlled way. Conclusively, a protocol for constructing audio-visual perception experiments using this system will be developed.

UHEAL: Uncovering Hidden Hearing Loss

Sam Watson, Research Assistant

Exposure to loud sounds has been shown to cause neuropathic damage which cannot be detected by standard audiometric testing, and is thought to cause indefinite problems when listening in noisy situations . The consequences and extent of this unmonitored damage in the human population is unknown.The goal of UHEAL is to bring together expertise from the fields of audiology, physiology and MRI to evaluate the repercussions of these neuropathic damages and assess measures to diagnose cochlear neuropathy in humans.

Innovative Hearing Aid Research – Ecological Conditions and Outcome Measures

Sergio Luiz Aguirre, Early Stage Researcher in the HEAR-ECO project

This PhD project at Eriksholm Research Centre focuses on the reproduction of realistic sounds scenarios and how to apply them for the measurement of listening effort. The long-term goal is to create new tests for examining the benefit of hearing-aid technology on listening effort in an ecologically valid environment. This project is jointly overseen by the Hearing Sciences – Scottish Section research group of the University in Nottingham (William Whitmer and Graham Naylor) and the Eriksholm Research Centre (Thomas Lunner). Additional collaboration with Hearing Systems, DTU, that will explore new ways to create the adequate sound field will be performed in the Audio Visual Immersion Lab (AVIL).
HEAR-ECO is a project which aims to develop and combine new tools and outcome measures for realistic communication, and translating these tools into innovative developments and evaluations of new technology for those with hearing loss. At its core, HEAR-ECO is training a new team of researchers working at the nexus of technology, psychology, physiology and audiology. This project has received funding from the European Union’s Horizon 2020 research and innovation programme under the Marie-Sklodowska-Curie grant agreement No 765329
