Sistema de transmissão de áudio para deficientes auditivos em ambientes ruidosos

Abstract

Classrooms or auditoriums quite often have some problems concerning their acoustic construction and do not offer a comfortable environment for lectures in order to understand what is being spoken, acoustic phenomena such as reverb and echo, can interfere with intelligibility. This problem affects with a greater intensity people who already have some degree of hearing loss. Knowing this issue, the project is conceived to develop an application on Android platform with Bluetooth technology transmission together with an electronic circuit that makes noise filtering and signal amplification for hearing impaired audio to promote social inclusion of hearing impaired. The methodology used to achieve the proposal prepared is obtained through analysis of related studies on the hearing correction using equalizers along with the use of advanced programming language to create hearing aid software focused on transmission of audio in a digital format. As final result has the attainment of an alternative circuit able to broadcast audio signals with good quality in noisy environments with an excellent cost benefit which meets the proposed objective efficiently.
