Recycled acoustic panel slashes power consumption

Technology News |
By Nick Flaherty


Warwick Acoustics has developed a capacitive acoustic panel without rare earth materials that slashes power consumption.

The ‘Clean Sound’ ElectroAcoustic Panel is on average up to 75% lighter, and consume up to 90% less power than other speakers, providing more benefits for electric vehicles as the noise of the internal combustion engine is eliminated. The panel is constructed using 100% upcycled and recycled materials in an environmentally friendly manufacturing process.

According to market researchers EDAG, car audio systems are used for roughly 260 hours per year. Given this level of use, a 1W reduction in audio system power consumption of an EV vehicle would save approximately 80g of CO2 emissions per year through reductions in electricity generation.

The ElectroAcoustic Panel audio system saves on average 50W of power consumption, with up to 10x this amount in high specification systems. This could save on average just under 4kg of CO2 emissions per vehicle per year in primary power consumption savings. 

“As automotive manufacturers undertake the rapid transition to electric mobility and a circular economy, every element of their supply chain and manufacturing process falls under close scrutiny,” said Mike Grant, CEO of UK-based Warwick Acoustics. “As the noise of the internal combustion engine is lost in the transition to EV, shaping the acoustic environment within a vehicle is a fundamental opportunity for manufacturers to redefine their competitive positioning in the market, and where only sustainable innovation will enable them to succeed.

“Warwick Acoustics’ commitment to making a positive contribution to the automotive industry meeting its environmental goals, including the decarbonisation of supply bases and the onboarding of new, sustainability-focused partners, is reflected in the technological solutions we provide. Our ElectroAcoustic Panels provide the ideal green solution to automotive OEMs seeking to implement a highly sustainable, recyclable, power and weight efficient and brand-defining solution into their products.”
