Acoustic Noise Reduction Solutions for University Classrooms

As a venue for daily instruction, classrooms have relatively high demands regarding the acoustic environment.

Issues such as significant sound reflection and excessively prolonged reverberation time in classrooms adversely affect the clarity of instructional audio. In response to these challenges, the CYATCO Acoustic Engineering Team has developed a targeted renovation plan.

The walls are adorned with wooden akupanels, featuring yellow oak wood-colored slats as the primary hue, complemented by light green acoustic fiber felt, which imparts a natural and warm ambiance. This design is not only visually appealing but also serves to disperse and absorb certain sound waves, thereby reducing sound reflection.

Additionally, square fabric-wrapped acoustic panels in white, grey, and green are strategically arranged on the walls. This further optimizes the acoustic environment while breaking up wall monotony and enhancing visual depth.

The desks and chairs within the classroom are organized neatly. The tablecloths exhibit a light wood color that harmonizes with the wooden sound-absorbing boards on the walls. The seats feature darker hues that resist dirt while providing a comfortable experience. The ceiling showcases a simple yet elegant white embedded design. Overall, this creates an inviting atmosphere conducive to learning.

The acoustic environment of the renovated classroom has seen substantial improvement; reverberation time is now maintained within an acceptable range while speech clarity has been significantly enhanced. Students report that even those seated in the last row can clearly hear instructional content. This acoustic engineering renovation project not only elevates teaching quality but also fosters a more comfortable learning environment for both educators and learners alike.
