The ‌Type A Sound Reduction Wall Panel‌ is a high-performance, ‌high-density acoustic insulation board‌ designed to block the transmission of airborne noise in demanding environments. Primarily used in ‌marine engine room boundaries, industrial plant walls, and equipment enclosures‌, its effectiveness stems from its ‌mass and density‌, which resist the vibration caused by sound waves, thereby reducing sound energy transfer.

How It Works: The Mass Law Principle

In line with basic acoustic principles, the sound insulation performance of a single-leaf panel primarily follows the ‌Mass Law‌: the greater the mass per unit area, the better the sound insulation at mid to high frequencies. Our Type A panels are engineered with high-density core materials to maximize this effect, providing a robust barrier against noise.

Design:

Another kind of propagation of sound is cross-media propagation. That is, from a medium, through the critical contact surface of the two media into another medium, at this time, the transfer of sound energy is essentially the transfer of vibration amplitude.

Cross-media propagation, the greater the difference between the density of the two media, the greater the loss of sound energy.

In practice, the air for human activities under normal space, so the greater the difference in density with the air material is generally very high density materials (much lower than the density of air in addition to the vacuum, but also really not much material), can be regarded as soundproofing materials.

The higher the density, the better the sound insulation. Such a material made of panels, called soundproof panels.

Product Advantages

Significantly reduces transmitted noise levels, protecting adjacent quiet areas or the external environment.

‌Fire Safety Integration‌: When made from non-combustible mineral wool, it contributes to the overall fire resistance of a wall assembly.

‌Easy Installation‌: Can be cut and fitted between or over framing members (studs, channels).

‌Durability‌: The dense, rigid structure is resistant to damage and sagging over time.

Typical Applications

‌Marine‌: Engine room casings, bulkheads adjacent to machinery spaces, boundary walls for accommodations.

‌Industrial‌: Plant walls separating noisy production areas from offices, enclosures for generators and compressors.

‌Commercial‌: Wall systems in recording studios, home theaters, conference rooms requiring high sound insulation.
