Master Thesis: Investigating Attentional Modulation of Otoacoustic Emissions: A Simulation and Experimental Comparison
Starting date: February 2025
Otoacoustic emissions (OAEs) are subtle sounds produced by the cochlea as a result of its active amplification processes. They are not only critical for understanding cochlear function but also serve as a valuable tool for non-invasive auditory diagnostics. Recent research suggests that OAEs may be influenced by higher-order processes such as auditory attention, making them a promising area of study to explore the interplay between cognitive and peripheral auditory mechanisms.
This Master thesis will utilize an existing cochlear model capable of simulating otoacoustic emissions. The candidate will test stimuli that have been used in recent experiments to compare simulation results with experimental data. A key focus will be implementing a mechanism within the model to simulate the ability to attend to a specific speaker in a “speech-in-noise” scenario, where male and female speakers are presented simultaneously. The goal is to determine whether attentional focus introduces measurable differences in the simulated OAEs.
Additionally, the thesis will aim to quantify these potential changes in OAEs due to attentional modulation and systematically compare the findings with experimental results. This project provides an exciting opportunity to bridge computational modeling with real-world auditory experiments, contributing to the understanding of how cognitive processes interact with auditory physiology.
Skills and Qualifications:
- Programming proficiency: Advanced skills in MATLAB, Python, or similar programming environments for implementing models and analyzing data. The cochlear model is written in Python.
- Signal processing expertise: Understanding of time-frequency analysis, filtering, and noise handling techniques.
- Mathematics skills: Proficiency in mathematical concepts related to differential equations, linear systems, and data modeling.
- Understanding of electrodynamics and circuit theory: Familiarity with concepts such as resistances, admittances, and their role in modeling physical systems. The candidate should be able to apply these principles to understand and work with the cochlear model.
- Experience with computational modeling: Knowledge of simulating physiological processes, preferably within auditory systems.
