When I conduct training for school employees, I like to start my presentations speaking in a “normal” voice. About halfway in, I turn on the instructional audio solution that is set up in the room.
I love the “wow factor” as teachers hear firsthand what a difference instructional audio makes. This reveal proves the technology’s effectiveness as they all understand how a similar setup could help in their classrooms.
Most teachers, principals, and paraprofessionals instinctively know that instructional audio helps amplify their voices, allowing their instruction and directions to reach every student, but instructional audio offers much more than that.
Here are three key reasons why instructional audio is crucial for today’s classroom.
1. It’s Not Just Amplification
Instructional audio provides even distribution of sound, not just amplification. This means that no matter where students are in the room, they can hear their teacher clearly. Often, teachers boast of their “teacher voice,” but speaking louder doesn’t always mean clearer. For certain words, such as ones that include an F or TH sound, speaking louder can have the opposite effect, making these words harder for students to understand.
There is a benefit for teachers, too. Teachers who speak loudly to be heard report being more tired and that can lead to more teacher absenteeism, according to one study. Teacher absences are not only costly for schools, but also disrupt students’ learning.
2. All Students Benefit
Instructional audio is proven to offer benefits not only to students who are hard of hearing. Decades of research, including the federal Mainstream Amplification Resource Room Study, known as the MARRS Project, prove that instructional audio helps those with learning differences, those in the back of the classroom and non-native English speakers.
