Deep Tech Takes: Lios
Startup Snapshot
Who: Lios
Where: Based in Ireland
What: A deep tech startup developing a new class of acoustic materials that reduce harmful low-frequency noise without taking up so much space.
Founders: Rhona Togher (CEO) and Eimear O’Carroll (CTO), founded in 2009
The technology
Low-frequency noise is notoriously difficult to block. It travels further, penetrates more deeply, and is a big challenge in modern soundproofing. Most materials either add serious bulk, sacrifice performance, or come with an environmental footprint that’s hard to justify.
SoundBounce takes a different approach. Developed by Lios, it’s a patented acoustic metamaterial that responds to noise and vibration using thixotropic properties. When exposed to vibration or sound energy, the material temporarily changes and dissipates that energy internally. Once the noise or vibration stops, it returns to its original state like a stress ball with an engineering degree.
SoundBounce is up to four times thinner than standard acoustic materials or insulation. It performs better at key frequencies, integrates easily into products and structures, and avoids compromises associated with traditional materials.
With patents and over a decade of development behind it, SoundBounce is ready for real-world use in industries where noise control and material efficiency go hand in hand.
Where it matters most
Noise regulations are tightening. Manufacturers and builders are expected to deliver quieter products, safer environments, and cleaner practices. Lios has a practical solution without making design harder.
Key applications include:
Construction, where wall and ceiling systems need to deliver high acoustic performance without increasing build thickness or complexity.
Industrial machinery, where vibration damping and noise reduction improve both safety and user experience.
Home appliances, where quiet operation is a competitive feature and low-frequency noise is a design bottleneck.
In each case, Soundbouncel offers a cleaner and simpler way to reduce noise without increasing material thickness or weight.
What’s next for Lios
Lios is moving from pilot stage into commercial deployment. The team is working with manufacturers to integrate SoundBounce into construction systems, machinery, and high-end appliances.
Discussions are ongoing with OEMs, licensing partners, and design teams looking to apply the material to their next generation of products. Lios is open to collaboration with partners who want to improve acoustic performance without adding weight, waste, or design compromises.
