Certification scheme for audio-inclusive design launched

Audio inclusivity is the design and management of sound environments to enable the estimated 30% of people with diverse hearing, cognitive and sensory needs to comfortably communicate, focus and participate. The new Sownd certificate independent verification scheme, which measures this aspect of’ acoustic performance, is run by hearing wellbeing specialists Sownd Affects.

Noise sensitivity

With around 30% of the population being noise-sensitive in some way – whether as a result of hearing challenges or neurodivergence – poor acoustic environments can significantly affect health, comfort and engagement for many.

The new scheme aims to address this accessibility gap. While inclusive design is embedded through policy such as the National Planning Policy Framework and the London Plan, the sector has so far lacked a robust independent method of verifying whether acoustic inclusivity is genuinely achieved post-occupation.

Evidence-based framework

Sownd certification offers an evidence-based framework that evaluates how spaces perform in real-world conditions rather than relying on design-stage predictions. Developed through direct engagement with noise-sensitive communities, the framework aligns with standards including BS 8233, BB93 and PAS 6463. Assessment is conducted using the proprietary Sownd Method, which evaluates spaces based on measured performance data. Spaces can be assessed at three levels, with the foundational bronze tier focusing on core acoustic metrics. 

Founder of Sownd Affects, Marion Marincat, who lost his hearing in his twenties, explained, “We developed this certification through direct engagement with noise-sensitive communities to ensure it measures what matters to people. This is about evidence-based performance, which ensures clarity and comfort. When these standards are embedded from RIBA Stage 0 onwards, participation and wellbeing improve for everyone.”

First certified building

The Oscar Acoustics innovation centre in Kent is set to become the first Sownd certified building. Ben Hancock, managing director of Oscar Acoustics, said, “We’ve been so impressed with Sownd Affects’ bold ambition, we just had to get involved. Having dealt with tinnitus for 25 years, I know the isolation that comes when spaces exclude you. This certification aims to make that a thing of the past, creating spaces that are more enjoyable and inclusive for all. I cannot wait for this to become mainstream.”

Oscar Acoustics’ products have been independently validated through the Sownd Method, enabling projects that use them to achieve bronze certification through a streamlined pathway, with testing conducted by the Institute of Sound and Vibration Research at the University of Southampton.
