I am a teacher and often teach in large classrooms where it is difficult to convey my voice to all students, especially in noisy environments. I'm thinking about buying a voice amplifier to improve my presentation and preserve my voice. Has anyone used such devices? Which models are most convenient and effective?
I chose a portable amplifier with a belt that can be worn on my belt , this teacher voice amplifier has been a real lifesaver, especially in large classes and noisy halls, and my voice now sounds clear and loud, which greatly improves interaction with students. One of the main selection criteria was the lightness of the device and long battery life.
