Um Protótipo de Detector da Direção de Sons Altos para Pessoas com Deficiência Auditiva

Abstract

People with hearing impairments, especially those with severe cases, are often at risk of accidents, due to their inability to react to auditory warnings. To address these risks, a solution was proposed: a device that detects potentially dangerous sounds and alerts the user to the direction of the danger. Research involved selecting suitable materials, microcontrollers, and sensors, as well as developing algorithms to calculate sound direction and interface with the user. Seven tests were conducted, four assessing the system's accuracy in different situation while the others focused on calibration, sensitivity, and control of the device. Test results were satisfactory, showing an expected performance trend in terms of accuracy and errors. This work represents an effort to enhance the safety and autonomy of individuals with heari impairments in their daily activities.
