SonoField Classroom Sound Field System
Every educator conducting a classroom session, no matter what the level and subject is, essentially relies on hearing comprehension of the learners. therefore, to a great extent, the quality of learning depends heavily on the ability of the students to hear the words of the teacher clearly and at normal loudness. But factors such as the distance from the teacher, poor room acoustics, hearing problems, and non-native students can dramatically lower the quality of education in classrooms.
Sound Field Systems
The SonoField by CETRX is designed to enhance audio quality and distribution in a classroom by eliminating most of the factors that degrade student hearing and comprehension. SonoField creates a Sound Field in the classroom by using two or more speakers to evenly distribute the sound from different sources throughout the room. Depending on the size and geometry of the classroom, wall mounted or ceiling mounted load speakers are used.
A key component of Cetrix SonoField is the vibrating loudspeakers that mount on the walls or on the ceiling in a classroom. A vibrating speaker uses a flat surface to produce sound waves in the environment, resulting in a uniform dispersion of the sound waves. A well placed speaker system consisting of two or four vibrating speakers will cover the whole classroom with sound waves that can be heard at all points of the room with nearly the same clarity and loudness.
IR Wireless Microphone
SonoField uses an infrared wireless microphone system for the teacher and students. IR wireless microphone uses optical waves that do not penetrate the walls of the classroom, making it possible to use the system in all classrooms in a school without the waves from one classroom interfering getting picked up by the wireless system in the next classroom. For convenience and freedom of movement and work with two hands, a necklace wireless microphone is used by the teacher. A handheld wireless microphone is dedicated to the students who for communication with the class and the teacher.
