This project aims <\/strong>to study the benefits of binaural perception with respect to sound source localization and the intelligibility of perceived speech in noisy environments. The evaluation of binaural benefit will be carried out by combining objective electro-physiological tests (auditory evoked potentials) and subjective tests (using the subject’s response in auditory perception tests). The study will include normal hearing subjects and subjects with severe or profound hearing loss who have received cochlear implants. The analysis of these tests will contribute to understanding and modeling the mechanisms involved in binaural perception, evaluating the benefits it provides, and understanding the factors that condition or limit these benefits, with special interest in hearing-impaired patients who use cochlear implants. The specific objectives<\/strong> of the project include:<\/p>\n\n\n\n

1. Development of advanced techniques for recording auditory evoked potentials (AEPs).
2. Development of specific protocols based on advanced AEP recording to analyze the electro-physiological responses associated with binaural benefit.
3. Development of computer applications that facilitate the use of AEP recording techniques and protocols by the scientific community and by professionals and users without specific technical training.
4. Development of subjective tests to evaluate binaural benefit.
5. Development of a binaural perception model based on objective and subjective measures.
6. Development of simulation tools for binaural perception with cochlear implants.
7. Evaluation of binaural perception benefit in normal hearing individuals using cochlear implant simulations, both in objective electro-physiological tests and in subjective tests.
8. Development of instruments to evaluate the benefit of binaural perception in both normal hearing individuals and cochlear implant users.
9. Evaluation of binaural perception benefit in individuals with bilateral cochlear implants.
10. Development of auditory training tools to improve binaural perception.
11. Development of computer applications that facilitate the use of binaural perception evaluation and auditory training tools by professionals and users without specific technical training.<\/p>\n\n\n\n

The main expected results<\/strong> of the project are: (1) Advanced techniques for recording auditory evoked potentials, using complex stimuli (binaural, with multiple sources, with control of phase shifts and delays, including speech and noise), and appropriate procedures for estimating evoked activity of the auditory pathways for these stimuli. (2) Modeling of the physiological mechanisms and limiting factors in binaural perception, both in normal hearing individuals and cochlear implant users. (3) Clinical protocols for evaluating binaural perception ability. (4) Auditory training procedures to improve the benefits of binaural perception, primarily for cochlear implant users.<\/p>\n\n\n\n
