Inspiration

Millions of neurodivergent people, including those with autism, ADHD, anxiety, PTSD, and sensory processing differences, struggle in loud, unpredictable environments. Sudden spikes in noise can cause sensory overload and freeze responses, making communication impossible right when help is needed most. I was inspired to create a solution that keeps people safe even when they can’t speak or advocate for themselves during a crisis.

What it does

SensorySafe continuously monitors the sound environment through a phone’s microphone and alerts users before noise becomes overwhelming. If the user freezes or noise remains dangerously high, the app automatically notifies trusted contacts. A simple wearable or pocket button allows manual alerts, and the app guides users to the nearest quiet safe space with calming, easy-to-follow instructions.

How we built it

We built SensorySafe as a mobile app that performs real-time sound pressure level analysis and tracks rising noise trends. The interface is intentionally minimal and grounding, reducing stress during alerts. We added automatic emergency contact messaging, along with a database of designated quiet zones that users can navigate to with a single tap.

Challenges we ran into

One major challenge was minimizing false alerts from sudden but harmless noise. We also had to optimize the audio processing to be fast enough to predict overload risk rather than respond too late. Designing a UI that remains usable and comforting during panic moments required close attention to accessibility and cognitive load.

Accomplishments that we're proud of

We are proud that SensorySafe supports independence for people who often have to avoid busy environments. Turning audio data into something that enhances safety, not anxiety, was a big achievement. We’re also proud that our solution considers both the user and their support network, giving everyone more peace of mind.

What we learned

We learned how important it is to involve lived experience in design decisions. Beyond technical audio processing and mobile development skills, we learned about inclusive and trauma-aware design, focusing on clarity, comfort, and reliability. This project reinforced that accessibility isn’t a feature, it’s the foundation.

What's next for SensorySafe

We plan to expand our quiet-space map through user contributions and partnerships with public venues. We also aim to personalize sensitivity levels using machine learning and integrate wearable feedback like vibration or gentle lighting. Our long-term goal is to make every public space feel safer and more welcoming for sensory-sensitive people.
