This project aims to investigate electrophysiological responses from the auditory system in real-life settings and assess the impact of the surrounding environment on these responses.
The electrophysiological responses are recorded with concurrent scalp-EEG and ear-EEG. The auditory stimuli are derived from the ambient sounds naturally occurring in the real-life environments. These sounds are recorded using ear-level microphones, processed, and delivered through a speaker via a sound tube connected to the ear-EEG earpiece. This is facilitated through a combined Portable Hearing Lab (PHL) and ear-EEG system. The same stimuli are used subsequently for lab-recordings, to disentangle motion and vision effects.
Understanding these electrophysiological responses from the auditory system is crucial for applications such as continuous estimation of audiometric parameters in real-life settings or optimizing sound processing in hearing aids.
The project is funded by the William Demant Foundation and T&W Engineering
