Area of Science:

  • Biomedical Engineering
  • Signal Processing
  • Audiology

Background:

  • Advanced hearing prostheses require accurate fundamental period estimation for effective sound processing.
  • Existing fundamental frequency estimation techniques have limitations in real-time applications for the deafened population.

Purpose of the Study:

  • To introduce and evaluate a real-time peak-picking device for fundamental period estimation in hearing prostheses.
  • To compare the performance of the peak-picking device against established methods like the electrolaryngograph, cepstral technique, and Gold/Rabiner algorithm.

Main Methods:

  • Development of a real-time peak-picking device for fundamental period estimation.
  • Comparative analysis of the peak-picking device with the electrolaryngograph, cepstral technique, and Gold/Rabiner algorithm.
