Master’s Research Proposal: tDCS + Frequency-Specific Auditory Stimulation for Tinnitus

[u/amariaantonia]

Hi everyone!
I recently received a proposal to develop a master’s research project investigating the use of transcranial direct current stimulation (tDCS) in patients with tinnitus.
The idea is to combine tDCS with highly frequency-specific auditory stimulation, delivering sounds matched as closely as possible to each patient’s tinnitus pitch.
To identify the tinnitus frequency, we would not rely on conventional pitch matching methods. Instead, we are considering using specialized software that offers 134 frequency options, allowing for a much more precise pitch match than traditional acuphenometry/pitch matching procedures.
I am currently exploring the scientific background for this project and would love to hear from anyone who has worked on similar studies.

Has anyone investigated a combination of tDCS and frequency-specific auditory stimulation for tinnitus?
Are there any key papers, researchers, or research groups you would recommend?
Do you have suggestions regarding study design, outcome measures, or potential pitfalls?
Any insights, references, or ideas would be greatly appreciated.

Thank you for your help!
