Episode 22: The Power of Acoustics – A Conversation with Rogan Kelsey from Lumi

In Episode 22 of our podcast, we dive into the fascinating world of acoustic design with Rogan Kelsey, Senior Sales Manager at Lumi. From critical listening environments to mental health settings, Rogan shares how acoustics shape our experiences, why sound quality matters in design, and how Lumi is pioneering sustainable, design-forward acoustic solutions.

The Journey from Sound Engineering to Acoustic Design

Rogan’s passion for acoustics started with his background in electronics and audio engineering. Early in his career, he learned that a well-designed acoustic environment is just as important as high-quality speakers for achieving accurate sound. This insight led him to experiment with materials, build multiple studios, and eventually start designing acoustic spaces for others.

For over 20 years, Rogan has refined his expertise in creating environments where sound is optimised for clarity, comfort, and impact. His journey from music production to acoustic consultancy showcases how vital acoustics are beyond recording studios—affecting everything from workplaces to healthcare settings.

Lumi: Innovation in Acoustic Design

At Lumi, sustainability and innovation go hand in hand. The company transforms recycled plastic bottles into PET acoustic panels, offering high-performance sound absorption with a strong design aesthetic. Rogan explains how these panels are not just functional but also visually stunning, allowing for custom shapes, colour layering, and bespoke designs that align with architects’ creative visions.

Lumi’s expertise extends beyond wall panelling, integrating lighting, baffles, and raft solutions to provide comprehensive acoustic treatments. Their approach ensures that each project is tailored—whether it’s for a corporate office, educational space, or hospitality venue.

The Science Behind Acoustics & Natural Sound

One of the most eye-opening parts of our conversation was Rogan’s insight into how we experience sound. He explains that acoustic design isn’t just about removing echoes—it’s about creating a natural balance.

Overly absorbent spaces can feel unnatural, making occupants feel disoriented or uncomfortable. On the other hand, excess reverberation creates distraction and reduces speech clarity. Rogan’s approach focuses on designing spaces where sound feels natural, enhancing comfort and functionality—a principle that Lumi integrates into every project.

Sustainability & the Future of Acoustic Solutions

Lumi takes environmental responsibility seriously. Their panels are made from 75% recycled materials, and zero waste from production goes to landfill. Instead, offcuts are repurposed for low-frequency absorption solutions, ensuring that every part of the process is eco-conscious.

With a focus on bespoke fabrication, Lumi can tailor solutions for any project, maintaining fast lead times thanks to their extensive stockholding. Whether it’s custom designs, rapid sheet supply, or full acoustic installations, Lumi is at the forefront of sustainable acoustic innovation.

Final Thoughts

This episode highlights how acoustics play a crucial role in our environments, from the way we communicate to how we experience a space. Lumi is proving that sound design can be both functional and beautiful, blending technology, sustainability, and creativity to create environments that truly enhance the way we live and work.
