Environmental noise in classrooms is a recurring challenge to the teaching-learning process, impacting concentration and speech intelligibility. In this context, this article aims to present an applied technological proposal for a selective auditory attention system for educational environments, based on signal processing principles and assistive technologies. The system is structured as a sound mediation architecture capable of dynamically prioritizing the voice of an authorized speaker without suppressing environmental perception. The tool uses digital signal processing (DSP) principles and bone conduction headphones to foster functional and balanced listening. It is concluded that the technology, by shifting the sound filtering effort from the student to the system, constitutes a viable path to reduce cognitive load and promote school inclusion.
