Sonic Series acoustic louvres reduce machinery noise by employing sound attenuation and absorption principles. Here’s how they work in the context of machinery noise reduction:

Reflection: The surfaces of the louvres are designed to reflect sound waves away from the source. The louvres redirect sound energy by strategically placing and shaping the slats or blades, preventing it from travelling directly towards the surrounding area.

Diffraction: Louvres can cause diffraction of sound waves, which is the bending of waves around obstacles. This bending disperses the energy, making it less focused and reducing the noise intensity that reaches the outside environment.

Absorption: Sonic Series acoustic louvres include sound-absorbing materials within their construction. These materials, such as acoustic rockwool or baffles, absorb and dissipate sound energy. This absorption process helps to decrease the overall noise level further.

Airflow Path Design: Louvres are engineered to allow air passage while minimising noise transmission. The slats’ design and arrangement are carefully considered to balance the need for ventilation with effective noise reduction.

Enclosure: In some cases, Sonic Series acoustic louvres are used to enclose machinery or equipment. This enclosure directs and controls the noise emitted by the machinery and prevents the spread of noise to the surrounding area.

Overall, Sonic Series acoustic louvres create a barrier that interrupts the transmission of sound waves from machinery to the external environment, combining reflective, diffractive, and absorptive elements to achieve effective noise reduction. This is especially important in industrial settings where machinery noise can significantly concern workers and nearby residents.

Sonic Series acoustic louvres serve several purposes when integrated into buildings:

Noise Control: The primary purpose is to control and reduce noise transmission out of the building.

Sonic Series acoustic louvres help maintain a quieter and more comfortable environment.

Ventilation: Sonic Series acoustic louvres are often used in ventilation systems to allow the free flow of air while mitigating the impact of noise. This is crucial for maintaining good air quality for air sensitive plant equipment.

Compliance with Regulations: Many local regulations and building codes have strict guidelines regarding acceptable noise levels in different types of buildings. The use of Sonic Series acoustic louvres helps ensure that buildings comply with these regulations.

Equipment Enclosures: In industrial settings, Sonic Series acoustic louvres are commonly used to enclose noisy equipment or machinery. This helps protect workers from excessive noise exposure and maintains a more pleasant environment.

Sonic Series acoustic louvres are designed to control and reduce sound transmission through openings, such as ventilation systems or building facades. They typically consist of slats or blades arranged in a specific pattern within a frame. The primary purpose of Sonic Series acoustic louvres is to attenuate noise while still allowing air passage.

Here’s how they work: When sound waves encounter the surfaces of the louvres, the energy is either absorbed, reflected, or diffracted. The arrangement of the slats and the spacing between them is crucial for achieving effective sound reduction. The louvres disrupt the direct transmission of sound waves, converting some of the acoustic energy into heat through air friction and absorbing materials, thus reducing the overall noise level.

Sonic Series acoustic louvres are commonly used in industrial settings, HVAC (heating, ventilation, and air conditioning) systems, and buildings in noisy environments to maintain a comfortable environment while minimising noise pollution
