EQUIPAMENT DEVELOPMENT FOR ASSESSING SOUND LOCATION IN HUMAN BEINGS
Sound location; hearing; auditory perception
Sound localization is the ability to identify the source of the sound. This skill is fundamental for the development of selective attention, is helps in oral communication and is known as one of the skills needed for central auditory processing (PAC). During the evaluation of the PAC, the assessment of this ability is made through the localization test in the five directions. The localization test used in the evaluation of the PAC, needs some adjustments in the applicability and has been discarded by many professionals for not having an equipment for this purpose. Thus, a search for priorities was carried out in order to verify patents field with this theme, verifying onlu parents that approached subject, with divergent objectives to that of this study. In view of this reality, the need arose to develop new equipment to assess the ability of sound localization and compose the PAC exam. Objective: in living beings. Methodology: This study consists of several states. 1) Equipment development. 2) Software development. 3) Production of sound stimuli. 4) Application of the test in human beings using the new equipment for auditory localization. The study sample will consist of a pilot group, formed by 10 adults with normal CAP; and other group, formed by 10 children with altered CAP. The results will be compered between the localization test in the 5 directions with the localization test with new equipment. Result: The equipment was produced at LATEC, with a patent field with the INPI. It consists of a circuit board, an amplifier, 5 speakers and software, which is registered. Human testing is in its early stages. Expected result: We hope that this product will be a differential for the localization test, collaborating with the diagnosis of the CAP.
