Abstract
A number of conventional group hearing aids have been produced. However, the problem with all of the conventional systems is that the direction of communication is one way, coming from the teacher to each student. A two way system in which the voice of a student is directly transmitted to other students (bypassing the teacher) has been in great demand. This is the very objective of the current study. We have developed a group hearing aid in a classroom of the school for the deaf in which the voice of a standing student is shared with each hearing-impaired student in the classroom.
