Lios

Lios is an Irish deep-tech company that specializes in advanced acoustic materials for noise and vibration reduction. Its flagship technology, SoundBounce, is a composite material that uses thixotropic properties—appearing solid at rest but flowing when exposed to energy—to attenuate low-frequency noise. This patented, sustainable material is designed to be thinner, lighter, and more effective than traditional acoustic solutions, enabling its integration into various industrial products without significant added bulk or environmental impact. Originally founded in 2009 as Restored Hearing, the company rebranded to Lios to better reflect its expanded focus on industrial noise pollution and materials science.

The technology is utilized by partners in sectors such as construction, aerospace, automotive, and home appliances to help meet sustainability goals and regulatory standards for noise control. By providing a high-performance alternative that saves space and enhances product performance, Lios enables designers to create quieter and more sustainable environments. The company has secured significant backing, including European Innovation Council (EIC) Accelerator funding, to scale its production and support its mission of eradicating harmful noise pollution globally. Lios operates from its headquarters in Dublin, Ireland, and works with global industry leaders to implement its acoustic innovations.
