We are tracking two minor bugs:
Q: Does the Sone 523 updated support wireless connectivity? A: Not natively, but it has a USB port compatible with select 4G/LTE dongles and Wi-Fi adapters (chipset RTL8812AU). An official Wi-Fi accessory is expected in Q3 2026.
Q: Is the data format compatible with LabVIEW or MATLAB? A: Yes. The updated device can export directly to .TDMS (LabVIEW) and .MAT (v7.3) formats via the Sone Manager Pro export tool. sone 523 updated
Q: My old Sone 523 scripts don’t work after updating. Why?
A: The Lua scripting API was expanded. Legacy scripts using deprecated functions (e.g., sleep()) must be revised. Refer to the migration guide appendix C.
Here is a quick reference table comparing old vs. updated sone ratings for common scenarios: We are tracking two minor bugs: Q: Does
| Perceived Loudness | Old Sone Rating (Stevens) | Sone 523 Updated (Zwicker) | | ----------------- | ------------------------- | --------------------------- | | Silent (Leaf rustle) | < 0.5 | < 0.8 | | Very quiet (Whisper) | 0.5 – 1.0 | 0.8 – 1.5 | | Quiet (Library) | 1.0 – 2.0 | 1.5 – 3.0 | | Normal (Conversation) | 3.0 – 4.0 | 4.0 – 5.5 |
Note: The numbers generally shift upward under the updated system. Do not panic if you see a "1.8 sone" label today—that is the equivalent of an old "1.2 sone" fan. Q: Is the data format compatible with LabVIEW or MATLAB
Older tests were often conducted in anechoic chambers (perfectly silent, non-echoic rooms). The updated standard requires testing in environments that account for typical room reverberation. If a bathroom has tile floors and a glass shower door, the reflected noise adds to the perceived loudness.
The "sone 523 updated" protocol introduces a reverberation correction factor, meaning manufacturers can no longer advertise laboratory-perfect numbers that are impossible to achieve in your home.
