We are a smart materials and acoustics company that is changing the way we interact with sound and providing noise control solutions in conditions conventional materials cannot address.

Coupling applied physics with intelligent design and manufacturing, we are pioneering a new class of multifunctional materials - called metamaterials.

SCIENCE BEHIND IT

Through our 16 years of R&D in applied physics, we have developed a proprietary algorithm that enables us to effectively optimize the acoustic design in any given situation.

industrial applications

Our technology addresses noise problems conventional materials cannot solve directly. Learn more about these special conditions and relevant industrial applications. 

Coupling our proprietary algorithm alongside a systematic manufacturing approach, we have the ability to “turn” a wide variety of conventional materials into sound absorbing materials.

 

Metamaterial is not in itself a new material - we shape solids to form various geometries such as tiny chambers or channels for different resonances. This gives conventional materials a high sound-absorbing quality.

Our metamaterial solutions enable us to inherit the natural characteristics from a wide variety of materials from plastic to metal: hence we are able to achieve acoustic performance in conditions previously impossible with conventional materials such as foam and rock wool.

 
 

CAUSALITY LAW IN SOUND ABSORPTION

Our discovery of this causality law enables us to design and control a large number of resonators and their dissipations.

In a given space, the total sound pressure level after reduction (SPL) through absorption for sounds in every frequency f has an upper bound limited by the thickness of the material, d, where c is the sounds speed in air.

In a given space, the total sound pressure level after reduction (SPL) through absorption for sounds in every frequency f has an upper bound limited by the thickness of the material, d, where c is the sounds speed in air.

It is important to understand this causality - given the same thickness, there is a direct absorption trade-off from one frequency to another.

We can maximise the absorption of a given space on specific targeted frequencies, whereas other porous materials such as rock wool and foam lack the flexibility to manipulate their resonators. This flexibility enables us to provide optimal sound reduction beyond conventional materials.

 

CUSTOMIZATION PROCESS

Our acoustic metamterials solution enables us to effectively provide customized noise control. The example below exemplify our ability to design a customized broadband acoustic solution.

Targeted "M" sound

The “M” shaped BLUE line is our spectrum noise target

Optimize resonances and dissipation

Upon obtaining the noise spectrum, we optimise the resonances and dissipation mimicking the “M” shape to address the noise source.

Realised result

After applying our metamaterials absorber, the original noise source decreases significantly from the blue to a relatively flat level as the red line spectrum.

INDUSTRIAL APPLICATIONS 

As the metamaterials field gathers momentum, a pragmatic approach is necessary to realize the promised benefits. We are pioneering the development of customized acoustic components that help our customer capitalize on the efficiency and performance that acoustic metamaterials technology delivers today.

We only address noise problems that cannot be solved by conventional materials directly. Among the many special capabilities of acoustic metamaterials, we have highlighted a number of qualities that have direct industrial implications.

 

High temperature

The wide variety of material choices enable our metamaterials to be made from metal, absorbing noise in a high temperature environment where conventional materials cannot maintain their form

Absorption near the noise source in all machineries is the most effective noise-control solution. This solution dramatically reduces the material and construction cost compared to traditional approaches.

Relevant applications: gas turbines, power supply systems, etc.

high air flow requirement

Side absorption by metamaterials can facilitate an effective noise control solution with ventilation.

Our silencer increases fan cooling capacity for heat-generating systems. The higher capacity enables better future generation of products.

Relevant applications: fan cooling system for heavy machinery, data-centre and consumer electronics

Low Frequency Sound

Through customization, we can achieve broadband low-frequency noise absorption better than any material found in nature.

Low frequency noise cannot be treated with conventional material. It is commonly found in large-scale machines. Our customised absorber can efficiently absorb low-frequency sound under limited space.

Relevant applications: heavy machinery, music with loud bass
