Improved Classroom Acoustics: A Guide to Enhancing Learning Environments

When it comes to education, effective communication of ideas and concepts is crucial. Clarity, accuracy, engagement, and consistency are essential in facilitating learning. Just as teaching in a dimly lit room can hinder comprehension, instructing in “acoustic darkness” can pose similar obstacles. Unfortunately, many classrooms are constructed with hard, sound-reflecting materials that lack sound-absorption properties. Thankfully, there are proven methods to enhance classroom acoustics. However, it’s crucial to pinpoint the specific acoustic issues you want to address before implementing solutions.

Understanding Reverberation

Reverberation refers to the echo or lingering sound that occurs as sound waves bounce around in a space. Hard surfaces create what is known as an “echo chamber,” where sound bounces relentlessly from one hard surface to another. The more pronounced the echo, the less intelligible the room becomes. Reduced intelligibility can result in misunderstanding and miscommunication, particularly with higher-frequency consonant sounds that are critical for comprehension.

The Impact on Classrooms

Classroom layouts have remained largely unchanged over the years. Typically, teachers stand at the front of the room, addressing rows of desks and seats. In larger classrooms, students can be as far as 40 feet away in K-12 settings and up to 150 feet away in college settings. As sound travels, its volume decreases by approximately 4 decibels for every 6 feet it covers. This means that within 12 feet, the volume is halved, and within 24 feet, it’s reduced to a quarter of the original level. When you factor in the ambient noise in a classroom (typically 40-50 decibels) and the noise generated by students, it’s no wonder that those seated at the back struggle to hear.

Instructors often find themselves in the unenviable position of having to raise their voices to be heard, which can lead to vocal cord strain, long-term damage, and even respiratory health issues. The need for a strident tone to overcome room noise can make students feel as though they are being shouted at or misunderstand the teacher’s intentions.

Classroom Panels

Finding a Solution

Acoustic panels offer a comprehensive solution to these challenges. By absorbing sound energy, these panels prevent sound reflections from interfering with the learning process. They also control the base noise floor, preventing uncontrolled reverberation that can smother program material. With acoustic panels in place, instructors no longer need to strain their voices, reducing the risk of burnout and tonal issues. Students, in turn, enjoy a better learning experience.

At Primacoustic, we’ve devised a simple formula to determine the necessary amount of absorption for effective results. Covering just 20% of a room’s wall surface area with acoustic panels can make a significant difference in eliminating acoustic issues in most classrooms. These panels can be strategically distributed on walls, ceilings, or, ideally, a combination of both.

These panels are available in various sizes, shapes, and colours, making them adaptable to any classroom design. They are easy to install and maintain while retaining their sound-absorbing capabilities indefinitely.
