What is an acoustic plasterboard wall?

As society progresses, human life is continuously improving towards greater safety and comfort. However, the pace of urbanization has led to denser and more crowded populations, gradually revealing various issues related to the human living environment, one of which is noise pollution. Living spaces like homes and hotels are places where people return to rest and relax after a tiring day's work, and these spaces require a quiet, private environment.

Sound Absorption Partition 1

1. What is an acoustic gypsum partition?

A gypsum acoustic partition is a wall system designed to absorb a portion of sound energy, helping to reduce echo and improve sound clarity within a space. Unlike sound-insulating partition systems, which are typically used to prevent noise from spreading between areas, acoustic partitions focus on treating sound reflections inside a single room, making the sound clearer and easier to hear.

When using specialized acoustic gypsum boards, the wall system can achieve a Noise Reduction Coefficient (NRC) ranging from 0.65 to 0.8. This effectively meets the acoustic standards for spaces like movie theaters, conference rooms, recording studios, or multi-purpose classrooms.

2. Structure of an Acoustic Gypsum Partition

The structure of an acoustic gypsum partition typically consists of an acoustic gypsum board installed directly onto a flat wall surface or integrated with an existing frame and wall layer. Below is a detailed breakdown of the components and functions within a complete acoustic gypsum partition solution.

  • Metal Partition: This is the main load-bearing component that shapes the partition's structure. The profile is often made from AZ50 galvanized steel to ensure durability and resistance to rust.
  • Acoustic Gypsum Board: This is a perforated gypsum board featuring various hole patterns (round, square, or slotted) and a specialized acoustic fleece backing. This layer is crucial for directing sound and maximizing absorption efficiency. Without the fleece backing, the acoustic performance will not be as effective as intended.
  • Accessories: These include screws, jointing tape, and specialized jointing compound, all of which ensure the overall aesthetic appeal and long-term durability of the entire wall system.

3. Advantages of an Acoustic Gypsum Partition System

Due to their superior technical properties and versatile applications, acoustic gypsum partitions are a popular choice for various projects, including conference rooms, recording studios, cinemas, schools, and hospitals.

Improved Sound Quality

These partitions help absorb sound waves, reducing echo and reverberation in enclosed spaces. As a result, sound becomes clearer and easier to hear, which is especially beneficial for areas requiring high-quality acoustics like studios, closed meeting rooms, auditoriums, or classrooms.

High Aesthetic Appeal

With a wide variety of perforated board designs (round, square, or slotted), acoustic partitions can be easily integrated into many modern and sophisticated interior design styles.

Easy and Fast Installation

The installation process is simple and quick, as the gypsum board is attached to a standard metal framing system. This saves both time and installation costs compared to traditional solutions.

Safe and Environmentally Friendly

Gypsum material is non-toxic, ensuring user health and safety. It is also suitable for green building projects that prioritize sustainable development.

4. Acoustic Gypsum Partition Price List

The cost of labor and materials for an acoustic gypsum partition can range from 700,000 - 900,000 VND per square meter, depending on several key factors:

  • Material Brand: Acoustic gypsum boards from reputable brands typically have a higher price because they meet strict standards for durability, sound absorption, and safety. However, investing in authentic materials increases the system's effectiveness and extends the lifespan of the project, reducing the need for future repairs.
  • Project Scope: Each project is unique in its area, shape, design complexity, and required acoustic standards. Large-scale or complex projects will require more materials and a longer installation time, thus increasing the overall cost.
  • Installation Team: Installing an acoustic gypsum partition requires precise technical skill to ensure effective sound absorption. An experienced team will guarantee consistent quality, high aesthetic appeal, and minimal errors. However, the cost of professional labor will be higher than that of a general contractor.
