Some pod brands mention ISO 23351-1. What does this standard actually measure, and why should I care?
ISO 23351-1 is the international standard for measuring speech privacy and acoustic performance in office pods and furniture. It was introduced in 2020 and has become the industry benchmark.
In plain English, it tells you how well a pod keeps conversations private.
| Rating Level | What It Means | Real-World Experience |
|---|---|---|
| Class C (Basic) | 20-25 dB reduction | Conversations are muffled but words can still be made out. Fine for quick calls. |
| Class B (Good) | 25-30 dB reduction | Speech is audible but not intelligible. Good for most business calls. |
| Class A (Excellent) | 30+ dB reduction | Speech is barely audible. Suitable for confidential conversations. |
Why It Matters for Your Office:
| If You Need... | Look For... |
|---|---|
| Quick calls, casual focus | Class C is fine |
| Professional calls, client discussions | Class B |
| HR talks, legal matters, executive conversations | Class A (ISO 23351-1 certified) |
