SOWND WITH
STANDARDS
Sound designed around people - not just ideas. For real humans. For how sound is actually lived.
The #1 acoustic certification for the built environment
Creating better connection and experience in social spaces.
Gone are the days when crystal clear sound was just a 'nice to have'. When aesthetics trumped acoustics and background noise refused to stay in the background. Customers wiped out by noise, revenue sinking, staff bolting. Endless user complaints, all driven by spaces that ticked boxes without actually delivering audio inclusivity - environments that work for some ears, but quietly exclude many others.
Say goodbye to spaces that look cool on Instagram, but feel exhausting when you're in them.
Times are changing. If you aren't pursuing audible comfort and connection, you're about to be left behind.
Noisy spaces are having a detrimental impact on human behaviour.

have a daily challenge of being noise-sensitive.
The commercial loss is enormous - and so is the opportunity to challenge the status quo and maximise ROI.
We're leading that shift with Sownd Certification: the only way to prove that a space is comfortable, audio inclusive and compliant.
Because sound doesn't just fill a space - it shapes how people feel within it.
Built with ISVR Southampton
The Institute of Sound and Vibration Research (ISVR) at the University of Southampton is a leading centre for acoustic research and education, known for its work on sound, vibration, and human response to noise. Our framework was developed, tested and implemented with ISVR to ensure it's grounded in rigorous research and real-world application.
Evidence-led, human-centred, and designed to be specified.

How does it work?
Bronze
The acoustic foundations you need to become a reputable sound comfort leader.
Silver
Elevate your acoustic baseline with operational excellence.
Gold
Multi-sensory alignment for a truly inclusive acoustic environment.
But first? You have to get the physics right.
Two routes to Bronze
The Integrated Route
3-4 weeksFor projects using an approved acoustic partner or product.
- 1An acoustic consultant specifies what treatment you need by following our framework.
- 2Our approved partner installs the acoustic solution.
- 3The project receives Bronze Sownd Certification and digital directory listing.
Approved partner
The Independent Route
4-6 weeksFor spaces with existing acoustic treatment or a non-approved product.
- 1Apply for your Bronze assessment.
- 2We visit to measure your space and document our findings.
- 3We carry out our Sownd framework analysis and apply recommendations (where applicable).
- 4The project receives Bronze certification and digital directory listing.

As Mayor of Hackney, I've always prided myself on our commitment to inclusion, but it wasn't until I learned about the impact of noise on the 30% of our community who are noise-sensitive that I realised we were failing them.

Upgrading for Audio Inclusivity, we have had the best staff retention in 8 years. It's definitely something I'd apply to all venues and I'd recommend others do it too.
Rebecca Stevenson
Founder, Signorelli Bakery & Coffee Shops
As a direct result of implementing Audio Inclusivity methods, we've seen dwell times increase in public venues and huge improvements in both customer and staff satisfaction.
