Limitless design opportunities, tailored to end-use environment and desired characteristics.
Low Frequency
Unique ability to attenuate low-frequency noise at unrivalled levels.
Value
Cost effective for industrial integration.
Sustainable Technology
Safe, non-toxic, and with a low environmental impact.
SoundBounce Material
SoundBounce is an acoustic metamaterial. An advanced, low frequency acoustic insulation, SoundBounce uses energy absorbing materials unique to the acoustics space. SoundBounce is a composite material, comprising of a naturally occurring responsive material enclosed in a cellular housing.
SoundBounce harnesses the phenomenon of thixotropy to provide superior noise attenuation. Thixotropic materials respond to energy. They activate when exposed to noise. The change in the material absorbs the sound energy. This unique property enables vastly superior low frequency attenuation.
An advanced metamaterial, SoundBounce is tunable to different frequencies enabling a more optimised solution to tackle your noise challenge. Designed for compliance with industry standards and regulatory requirements, SoundBounce is a non-toxic, sustainable solution to noise pollution.

Housing
The responsive SoundBounce material is housed in a cellular support structure to activate the advanced material.
The flexible structure contains cells, or pockets, where the active material is held. The thixotropic material is sealed airtight into this flexible housing structure.
The housing can be customised, as can the active material, to tackle specific noise challenges and environmental conditions that you want to address.
The housing structure is adaptable in terms of material selection and shape. The housing can be chosen to provide additional desired characteristics including and not limited to thermal wicking, flame resistance or retardancy, structural strength, or insulating properties.
Evidence
When it comes to noise reduction, low frequencies are the key challenge. The main sources of low frequency noise are engines, airflow, and anything that vibrates.
Independent testing shows SoundBounce out performs commonly used acoustic materials. SoundBounce has been rigorously tested and verified by acoustic labs around the world.
SoundBounce reduces noise more effectively at low frequencies, and by three times across all frequencies. SoundBounce is four times thinner – enabling designers to create smaller, lighter products with a significant reduction in noise – and it is cost-competitive and a sustainable material.
