How Good Audio Helps Students Learn

Author: Meghan Kennelly


We’ve explored why clear audio matters in business meetings and the same can be said when it comes to the classroom. In fact, clear audio not only matters in this setting, it’s crucial.

Audio is the foundation to effective learning and essential to student achievement.

The most popular audio solution in the classroom is an integrated microphone system. The main use is to help amplify audio to all corners of the classroom so the speaker can be heard clearly. It’s also a great tool to implement for remote learning environments and hearing-impaired students.

Recent studies have validated that integrated classroom audio is a proven tool to improve student’s opportunities to learn. According to The Mainstream Amplification Resource Room Study (The MARRS Project), their findings concluded that there were multiple benefits when voice amplification was added in the classroom.

Some of the key benefits found were:

Improved attention: a classroom audio system can help enhance a speaker’s pronunciation, tone and inflection, which enables the students to better comprehend. According to the MARRS study, when students receive audible instruction with an amplification, all commented that the amplified voice helped them pay attention and better understand directions.

Increased classroom participation: if a student cannot hear or understand correctly, there is often a lack of confidence to participate in any discussion or ask for further explanation. With improved classroom audio and a better grasp of concept, the assurance brings forth more student contributions.

Better classroom management: Enhanced audio can cause less stress in the classroom and fewer discipline issues. With the help of microphone amplification, teachers can now speak in their natural, soothing voice to teach their lessons and students no longer feel as though they are being yelled at.

Improved Academic Success: Sound field studies show that amplifying a teacher’s voice results in exceptional improvement in reading and language test scores for all students at all elementary levels. The evidence for improved teaching and quality of instruction is reflected in the statistically significant gains in reading and language achievement test scores for students included in classrooms using amplification (students with and without hearing loss).  These improvements were evident after only one year of use and the improved academic scores have been maintained for as much as 3 years.  
As we’ve said before, insuring the “A” in A/V is up to par is of utmost important. We have to work so much harder to understand someone when the sound quality is poor or choppy, and that work takes up brain power that is needed to devote to understanding and absorbing the message, not just discerning the words. Find the right audio solution for your classroom and see the benefits above first-hand.
