LIVE SOUND METER / GUIDE & INFORMATION
Keep a useful personal noise record
Save enough context to understand a result later, with a template you can reuse for each session.
Record what changed, not just the number
Start with the question you want to answer. “Did closing the window reduce the average?” is easier to investigate than an isolated reading. Give the source and condition a short name, then keep the measurement setup consistent.
A copyable session note
Copy this fictional example into your own notes and replace every field with your actual setup and observations. Enter the useful context in Report notes before exporting.

Comparison file: fan-high-60s.csvWhat each export contains
Stop measuring before exporting. Save report opens a local document you can print or save as PDF; Download CSV saves data for analysis. Neither export contains audio.
| Export | Included information |
|---|---|
| Report / PDF | Whole-session statistics, device and timing information, notes, final 30-second history and last available spectrum snapshot. |
| CSV | Session metadata and energy averages for approximately one-second intervals, plus a final shorter interval where applicable. |
Match the record to the question
Compare the whole-session averages for sustained changes. Use the history and observed events to explain bursts. The exported history covers only the final 30 seconds, even if you measured longer; CSV provides interval records across the captured session.
Keep original exports together and use filenames that identify the source, condition and time, such as 2026-10-22-fan-low-run1.csv. A new measurement replaces previous statistics, so export before restarting.
Privacy and formal use
Notes and files can reveal locations, schedules or device details. Include only what you need and consider what to remove before sharing.
