Tuneable Acoustic Noise DampEning Material

Periodic Reporting for period 1 - TANDEM (Tuneable Acoustic Noise DampEning Material)

Reporting period: 2019-06-01 to 2020-05-31

Existing acoustic materials do not meet the challenges of the increasingly noisy modern world. Thick and heavy slabs of materials are required to block out low frequency noise, like that of cars and jet engines. Increasing production cost, product size, and emissions. Industries are facing increasingly stringent regulations, and don’t have the technology to comply.

SoundBounce is an acoustic metamaterial providing superior noise reduction. It bypasses a critical technical bottleneck enabling the creation of smaller, lighter products with substantially reduced noise output. This is critical in the construction, automotive, power generation and aerospace sectors where space is at a premium.

SoundBounce provides game-changing advantages: 100-1000x improvement on current state-of-the-art; 3x volume reduction; customisable; unique ability to attenuate low frequency noise; and clean technology.

Market leaders in the €8 billion acoustic materials market have demonstrated their clear demand for the scaled up SoundBounce technology. Market growth is being driven by more stringent regulation, increasing social demand for lower noise emissions, and a rapidly urbanising population.

The SoundBounce team is uniquely positioned to deliver this groundbreaking technology to the market, with decades of commercial experience and deep technical expertise. Project TANDEM will advance the SoundBounce technology completing the remaining scale-up and commercialisation of the technology.

The EU is committed to significantly decreasing noise pollution and SoundBounce has the ability to address this ambitious challenge.
Work carried out was in line with expectations and objectives for Year 1. We have made the anticipated progress towards the industrialisation and commercialisation of SoundBounce. The team has expanded to incorporate experts in chemistry, acoustics, applied mathematics, communications, project management, and sales.

We worked on testing and characterising system variables gaining further insights into the complex SoundBounce system. We developed new designs and formulations of SoundBounce for research and commercial projects.
Mathematical modelling was successfully established as an integral part of research and development activities. Modelling continues to advance towards use in product development.

In parallel, we worked on identifying and incorporating the requirements of customers and industry regulations into the product development cycle. Customer pilot projects ensure SoundBounce development is informed foremost by the needs of the customer.

We are now working on the process and scalability tasks that will refine the design of SoundBounce to transition to industrial scale. We conducted a feasibility study of multiple manufacturing methods and have selected a process for scaled manufacturing.

Foundational activities involved in commercialisation of the SoundBounce technology have taken place in Year 1. We have built a pipeline of customers that will design SoundBounce into future products and established relationships with potential global manufacturing partners for the product. The pipeline contains companies across diverse sectors including aerospace, automotive, appliances, construction, and furniture.

We conducted an audit of our marketing and communication activities and set our priorities for Year 1. Typically events form a significant portion of our marketing efforts so this will be refined in light of Covid-19 event restrictions. Prior to Covid-19, we attended and presented at events both nationally and internationally on the topics of advanced materials, noise regulations, and intellectual property management. Positive media coverage was received throughout the year, especially upon the announcement of our funding via the SME Instrument.
Existing acoustic materials do not meet the challenges of the increasingly noisy modern world. Thick and heavy slabs of materials are required to block out low frequency noise. Industries are facing increasingly stringent regulations, and don’t have the technology to comply.
Critically, no material on the market outperforms the mass law, a severely limiting technological barrier. By overcoming the theoretical constraints of the mass law SoundBounce is fundamentally unlike anything available on the market today. This continues to bear out in new SoundBounce designs developed and tested in Year 1 of Project TANDEM, and advancements over the current state of the art in acoustic materials continue to be made.

The main way in which society benefits from SoundBounce is by gaining the ability to reduce low frequency noise in a space efficient way. Customers can make their products quieter, meet regulatory requirements, save space, and save costs by using SoundBounce.
By saving space, the overall reduction in bill of materials required for manufacture provides a sustainability benefit both to companies in the market and to society at large.

Sustainability is increasingly a key consideration for adoption by our customers and a core aspect of our approach to providing acoustic materials. In addition to the environmental advantages with respect to noise, the materials used to make SoundBounce have a low environmental impact (aligned with the EU’s Sustainable Development Goals). SoundBounce’s reactive thixotropic materials are safe, non-toxic, recoverable and recyclable at end of life.
