We may not even realize the breadth of invisible barriers our kids face each day during class. These include the inability to access the instruction because of how a teacher presents a lesson or where they are projecting their voice in the classroom, learning and/or language ability and level of the student, poor acoustics of the physical space, and downgraded audio quality when streaming lessons online. Technological advancements in classroom audio distribution systems (CADs) have helped meet a variety of such needs for teachers and students, with greater demand for easy-to-use sound technology given the rise of remote and hybrid learning, concerns regarding missed learning, and the need to ensure equity and access as education rapidly evolves. 

How was your classroom arranged this last school year? How did the arrangement affect your instructional practice? How did it affect student learning? Do you think having an audio system might have made a positive difference for everyone in the classroom? 

We know that if students can’t clearly see a lesson, they can’t be expected to retain the information. But did you know the same is true of hearing? Clear audio is essential to learning, but hearing loss, temporary impairment from an illness, and common classroom sounds can all get in the way of student learning.

In the first part of this series, I covered the various challenges that teachers face when dealing with sound in the classroom. When taking hearing loss, distance, and sound absorption into consideration, it can be hard for educators to find their teacher voice. So, what allows educators to be heard and can help improve teaching and learning in the classroom?

A long time ago in a classroom far away, a 20-something student sat in a class titled Speech Communication in the Classroom. The professor explained that among the many concepts learned in the course, one of the most important would be finding your voice. Throughout the semester, each student had multiple opportunities to stand and deliver his or her lesson to the class. Of course, each student would receive a grade and comments on their performance. At the end, the entire class would receive an impromptu mini lesson on teacher voice. Personally, I thought this old man couldn’t hear! I was not entirely wrong, but that is another story.
