Certified quiet — numbers procurement teams can verify
A soundproof claim is only worth the report behind it. LullPod pods are tested by TUV Rheinland, their materials by SGS, and everything is built in an ISO-certified factory. Full reports are shared with procurement teams during tendering.
Tested performance
| Test | Result | Verified by |
|---|---|---|
| Sound insulation | Rw+Ctr = 30dB (±5dB) | TUV Rheinland |
| Reverberation time | RT = 0.25s | TUV Rheinland |
| Noise isolation class | NIC = 32 | TUV Rheinland |
| Formaldehyde — acoustic cotton | Zero, fiberglass-free | SGS |
| Formaldehyde — polyester panels | Zero | SGS |
| Antibacterial surface | 99%, E0 grade (PR series) | Panel test report |
What the numbers mean
Rw+Ctr = 30dB — a 30-decibel reduction takes a typical 65–70dB gate area down to library-level quiet: conversations outside the cabin become background murmur. The ±5dB tolerance is the declared accuracy of the test, not a weaker promise.
RT = 0.25s — sound inside the cabin decays in a quarter second. No echo, no hollow box effect; the interior stays acoustically comfortable.
NIC = 32 — a standardized isolation class engineers can verify in the field after installation, so the number you buy is the number you can audit.
Zero formaldehyde — the materials inside an enclosed cabin are tested for air quality, not just structure: fiberglass-free acoustic cotton and zero-formaldehyde polyester panels, with SGS reports.

Common questions
Is the soundproof performance certified?
Yes. TUV Rheinland testing: Rw+Ctr = 30dB (±5dB), RT = 0.25s, NIC = 32. Reports are shared during procurement.
Are the materials eco-friendly?
Yes — fiberglass-free, zero-formaldehyde acoustic cotton and polyester panels, with SGS test reports.
