At LSTN, we believe great design creates spaces that connect people. Acoustics and AV are key to making environments inclusive.
When we were recently asked to advise an RIT student on restaurant acoustics for the Deaf and Hard of Hearing (DHH), we initially didn’t realize just how important acoustics are to the DHH community. But as we explored DeafSpace principles, one thing became clear: acoustics are critical for the DHH community.
DeafSpace & Acoustics
Developed by Campus Design and Planning at Gallaudet University, DeafSpace is an architectural approach that prioritizes accessibility for the DHH community. While lighting, sightlines, and spatial design are key, acoustic design is just as critical—especially for those using hearing aids or cochlear implants. Poor acoustics—background noise, reverberation, and mechanical hum—can turn a space from welcoming to overwhelming.
Many in the DHH community also engage with their surroundings through vibrations, lighting, and air movement. Thoughtful acoustic design doesn’t just reduce noise—it enhances multi-sensory awareness, making spaces more intuitive for everyone.
How We at LSTN Improve Accessibility Through Sound
- Balanced noise control – Keeping spaces quiet enough for conversation with just enough sound masking for speech privacy.
- Smart sound absorption – Using materials that reduce noise buildup without making spaces feel dull or lifeless.
- Thoughtful space planning – Separating noise-sensitive areas from louder environments, and where applicable, using…
- Sound-blocking elements – Such as partitions, screens, and materials to prevent sound spill.
- Tactile floor systems – Designing floors that provide subtle feedback to enhance situational awareness.
Technology That Bridges the Gap
AV technology can be a powerful tool for accessibility. Here’s how we’re integrating it into our AV designs:
- Next-gen ALS (Assistive Listening Systems) – BYOD (Bring Your Own Device) solutions, automatic real-time transcription & translation.
- Visual support – Supplemental video screens for ASL, closed captioning, and real-time translations.
- Enhanced audio experiences – matching loudspeaker system design with the acoustics of the environment to provide improved speech intelligibility and uniformity for the hard of hearing.
- Smart reception kiosks – Intuitive touchscreen stations that empower DHH visitors to communicate with staff, access real-time information, and navigate unfamiliar spaces with ease.
What’s Next?
We’re constantly learning, testing, and refining. From acoustic testing validation measurements and post-occupancy surveys to next-gen AV systems for cultural spaces, we’re committed to building more inclusive environments —esp where sound works for everyone.
Stay tuned as we’ve got a number of things in the works that we’re excited to share soon!
