Engineering
A new benchmark
for acoustic comfort.
Absolute Silence is more than a motor upgrade — it's a system rethink. Coulisse's in-house research showed that most sound doesn't come from the motor alone, but from vibrations traveling through brackets, tubes, and cassettes. That's why the engineering team re-designed every detail.
Hardware that isolates vibration. Motors tuned for softer, lower tones. Software that controls speed and movement for smoother operation. Together these elements create Motionblinds that run up to 15 dB quieter than standard systems — a new benchmark for acoustic comfort in real spaces.
By the numbers
The vision
Everybody claims 'quiet.'
We built a standard.
The promise of 'quiet' is everywhere in the window covering industry — but without a measurable standard, those claims are hard to trust.
Coulisse's engineering team, led by Engineering Manager Bas Klein Tuente, built a purpose-built sound lab in the Netherlands and discovered that silence isn't just about the motor — it's about the whole system. The result: Motionblinds re-engineered to run up to 15 dB quieter than any competitor measurement we've seen.
Proven in the lab
64 microphones.
Zero doubt.
In Coulisse's custom-built, soundproof lab in the Netherlands, every Motionblinds motor is measured and recorded under identical conditions. An advanced sound camera with 64 microphones pinpoints where noise begins and how it moves through the system.
Two motorized shades can be tested side-by-side in the lab — so you can hear the difference and see the data. The video here shows exactly how Motionblinds performs under real lab conditions.
For South Florida homes
Bedrooms. Home theaters.
Early morning pool-deck coffee.
The kind of rooms where a loud motor is the problem — a partner still asleep, a voice call in progress, a quiet conversation. Absolute Silence was built exactly for these moments. We install them across Miami-Dade, Broward, and Palm Beach.
