Irish Physicists Win European Inventor Award 2023

Munich, 4 July 2023 – The European Patent Office (EPO) announced today that Irish inventors Rhona Togher and Eimear O’Carroll are the winners in the ‘SMEs’ category of the European Inventor Award 2023. Selected from over 600 candidates, these inventors created an advanced acoustic material that reduces noise to address chronic sleep issues.

Togher and O’Carroll confirmed they were “honoured to win the European Inventor Award in the ‘SMEs’ category and would like to express our sincere gratitude to the European Patent Office. This award recognises many years of hard work and commitment to making the world a quieter place. It is a genuine privilege to be acknowledged alongside so many noteworthy inventors who have made such significant contributions to their fields.”

According to the European Environment Agency (EEA) approximately 20% of the EU population lives in areas with unacceptable noise and vibration levels. High noise levels have been linked to poor sleep and higher instances of heart problems. Due to noise pollution, the EEA estimates that 22 million people across Europe currently suffer from chronic high annoyance, whilst 6.5 million suffer chronic high sleep disturbance. Exposure to loud noise can also cause high blood pressure, heart disease, sleep disturbances, and stress.

A sound solution for millions of people

Togher and O’Carroll’s invention, SoundBounce™, is a composite technology that reduces the negative effects of loud noise. It consists of a responsive material housed within a cellular structure that responds to agitation by becoming liquid and absorbing energy. One of its innovative features is the invention’s cellular structure; the second is a thixotropic gel (capable of liquefying when agitated and resolidifying when allowed to stand) placed inside the cells. Once sealed, they work together to dampen sound, reducing noise transmission from one space to another. This new material can also be integrated into machinery and vehicles to reduce noise output. It can be used in the automotive, construction, aerospace and home appliance industries.

This material is particularly effective at low frequencies, which present a significant challenge connected to products with engines, vibrations, and airflow. SoundBounce’s thinner material means that aeroplanes or vehicles using it could be lighter, thus reducing fuel consumption and leaving more space. In addition to the environmental advantages related to noise reduction, the materials used to make SoundBounce have a low environmental impact as they are non-toxic, and recyclable at end of life. Since SoundBounce was created, Togher and O’Carroll’s company has developed partnerships with renowned organisations such as the European Space Agency.

Togher and O’Carroll explained how the award “serves as a reminder of the importance of innovation and the impact it can have on our society. We hope that this recognition will inspire others, especially young girls, to pursue their own inventions and to continue to push the boundaries of what is possible.”

The Irish duo behind the innovation have been named winners in the ‘SMEs’ category for this year’s European Inventor Award, which recognises outstanding inventors with inventions patented in Europe. All the winners of the 2023 edition of the European Inventor Award were announced at a hybrid ceremony today in Valencia (Spain).
