Warwick Acoustics in the UK has developed a sustainable audio system for automotive designs that reduces weight and power consumption.
The ‘Clean Sound’ ElectroAcoustic Panels use 100% upcycled and recycled materials without rare earth metals. The panels are also produced with an environmentally friendly manufacturing process.
The capacitive technology used in the panels make them 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 upcycled and recyclable materials include advanced polymer constructions from leading global materials partners and waste materials used by other industries such as the IT industry. Unlike conventional systems, ElectroAcoustic Panels contain no rare earth metals, avoiding the need for environmentally damaging mining techniques.
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 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.”
