How to perform sound insulation treatment on the space of a school's music classroom?

Music is an indispensable part of comprehensive quality education, and generally, schools will build professional music classrooms on campus. The core issue in creating such spaces is how to properly handle the sound isolation of music classrooms. This article will elaborate on the methods for sound insulation and absorption renovation of music classrooms in educational institutions, and also compile a list of core acoustic materials for this project to provide reference for the construction implementation.

How to Create a Music Classroom with Both Sound Insulation and Absorption

Most school building spaces are constructed with cement brick walls. If such structures are not professionally sound-insulated, indoor noise can easily spread to adjacent classrooms and corridors. At the same time, it should be noted that cement materials do not have any sound absorption capacity. When students rehearse in bands or orchestras, a large amount of annoying reverberation and echo will be generated in the space, making it difficult for students to hear their own parts clearly in group performances, thus affecting the rehearsal effect. However, solving this problem is not complicated. By following the steps below, the acoustic effect of the music classroom can be effectively improved.

Step 1: Arrange sound-absorbing materials throughout the music classroom

The core function of sound-absorbing materials is to absorb sound waves. Reasonable installation of sound-absorbing panels in the music classroom can significantly reduce the reflection and rebound of sound waves, thereby reducing reverberation and echo in the space. Sound-absorbing materials need to be arranged at key indoor acoustic positions, and the best installation points include:

- The internal and external corners of each wall

- The corner positions of the ceiling

- The ceiling directly above the main sound-producing area in the classroom

The installation process of sound-absorbing materials is relatively simple, and construction can be carried out by referring to professional installation tutorials for fabric-wrapped sound-absorbing panels.

Step 2: Install acoustic diffusers at key positions

After arranging the sound-absorbing materials, an appropriate number of acoustic diffusers can be added indoors. If sound-absorbing panels "absorb" sound waves, then diffusers evenly disperse sound waves throughout the space. They can not only reduce excess reverberation and echo but also maintain the vitality of the indoor sound field and the sense of space atmosphere, making the listening experience more natural. The installation positions of diffusers need to accurately correspond to the first reflection points of the classroom—that is, the positions on the walls and ceiling where sound waves first reflect. These points have the most critical impact on the overall sound quality of the room. The first reflection points of the classroom can be located through professional video tutorials, marked with masking tape, and then the diffusers can be installed and the sound field调试 can be performed to optimize the listening effect of the music classroom.

Step 3: Install professional soundproof doors

The above two steps mainly optimize the internal acoustic effect of the music classroom. To prevent indoor sounds from disturbing students in other classes outside, it is necessary to install professional soundproof doors. Soundproof doors are overall heavy and structurally strong. With their high-density material properties, they can effectively block the outward transmission of most noise without additional sound insulation treatment.

Step 4: Seal the door gaps

To further improve the sound insulation and absorption effect of the music classroom, soundproof door gap sealing kits can be used to fully seal the gaps of the door. Such kits can accurately fill all gaps at the top, bottom, and sides of the door. The standard for judging qualified installation is that no light can penetrate through the door gaps after the door is closed.

Step 5: Optimize in combination with the HVAC (Heating, Ventilation, and Air Conditioning) pipeline layout

If the HVAC pipeline of the music classroom is independently arranged and not shared with adjacent rooms, after extending the door frame and installing the soundproof door, RSIC-1 sound insulation clips can be added to form sound insulation gaps between the layers of gypsum boards; at the same time, it is recommended to lay 5/8-inch gypsum boards and apply green glue damping agent between the layers to further improve the sound insulation effect. If the music classroom shares the HVAC pipeline with other spaces, this step can be skipped.

Sound Insulation Renovation of Music Classrooms: 4 Essential Types of Core Materials

After understanding the core construction steps for sound insulation of music classrooms, the following will introduce the core sound insulation and absorption materials suitable for this project to facilitate construction implementation.

1. Wall and ceiling sound-absorbing panels

Sound-absorbing panels are the core materials for renovation, and schools can choose suitable styles according to the space size and budget of the music classroom.

Fabric-wrapped sound-absorbing panels: They can effectively reduce indoor reverberation and echo, and have a variety of sizes and colors to choose from, which can be designed to fit the overall decoration style of the school. Fabric wall sound-absorbing panels have excellent sound absorption performance, with more than 100 colors available. The panel thickness includes four specifications: 1 inch, 1 1/8 inches, 2 inches, and 2 1/8 inches. For school music classrooms, the 2-inch thick style is recommended.

Polyester fiber sound-absorbing panels: Polyester fiber sound-absorbing panels can also effectively suppress reverberation and echo, creating a high-quality rehearsal and listening environment for students, and their price is more affordable than fabric-wrapped sound-absorbing panels. The sound-absorbing panels are made of 100% polyester material, non-toxic, no allergens, anti-mildew, and no formaldehyde added. Their color, size, and thickness can be customized; the conventional panel thickness is 0.5 inches, 1 inch, and 2 inches, the standard sizes are 24×48 inches and 48×96 inches, and any size within 48×96 inches can also be customized.

BAC bonded acoustic cotton sound-absorbing panels: If the school needs to strictly control the renovation budget, this sound-absorbing panel is a cost-effective choice. The echo elimination panel is suitable for noise control in various spaces, including school music classrooms. It can be installed as a wall sound-absorbing panel or used as a hanging baffle; the panel is made of recycled BAC materials, which can participate in the LEED™ green building certification of the U.S. Green Building Council and obtain corresponding points. It also meets the Class A fire rating, is formaldehyde-free, anti-fungal, prevents mildew growth, and is 100% recyclable.

CFAB cellulose sound-absorbing panels: As a cellulose-based dual-effect panel for acoustics and heat insulation, it can effectively control the indoor sound field and reduce the impact of air-borne sound; its material has high density and excellent NRC (Noise Reduction Coefficient) rating. Although it cannot completely block sound, it performs well in sound absorption, reducing reverberation and echo, and heat insulation.

Yipai's cellulose-based material is an innovative product in the industry, made of 65%-75% recycled materials. It is an environmentally friendly alternative to traditional glass fiber panels, helping schools obtain LEED green building certification points; compared with spray foam insulation materials, this panel is more convenient for construction and installation, and can be easily disassembled if there are adjustments in the later period, which is an advantage that spray foam insulation materials do not have.
