This project was the acoustic construction of a professional music training institution’s vocal classrooms. As a space for vocal practice and instrumental teaching, the original room had strong sound reflection, which was prone to sound distortion and pitch deviation, affecting the teacher’s accurate judgment of the students’ timbre. At the same time, the sound insulation between classrooms was insufficient, and teaching activities easily interfered with each other.

Fabric-wrapped acoustic panels were used for full-wall acoustic treatment of each classroom. The high-density acoustic core wrapped with breathable flame-retardant fabric has an NRC rating of 0.85–0.95, which can achieve balanced full-band sound absorption, effectively eliminate indoor standing waves and reverberation, and ensure the authenticity and clarity of vocal and instrumental music sound. The soft fabric material can also avoid sound reflection damage to the hearing of teachers and students during long-term training.

The product supports customization of multiple fabric colors, which can be matched with the lively and artistic decoration style of the training institution. All fabrics meet the Class A fire protection standard, which meets the safety requirements of commercial training places. After the transformation, the acoustic environment of each classroom has reached the professional teaching standard, the sound is pure and undistorted, the mutual sound interference between classrooms is significantly reduced, and the teaching quality and learning experience are effectively improved.
