A New Proposal For Filtered Speech And Binaural Fusion Tests

Abstract

This work proposes to implement and evaluate filtered speech and binaural fusion tests in Brazil, using digital voice signal processing techniques for filtering. These techniques allow for more abrupt filtering without introducing phase distortions into the filtered signal. After filtering, the signals were applied to adult individuals with normal hearing and without significant otological history, using phonetically balanced words from Brazilian Portuguese. The results were consistent with the existing literature, however, more research is needed, both with normal and pathological individuals, so that we can analyze the sensitivity and effectiveness of this technique in evaluating Central Auditory Processing.
