- Hum reports should be handled without ridicule and without exaggeration.
- Self-reported experience is not a substitute for instrumented local measurement.
- FAL's public posture is measurement first, interpretation later.
How this item is held in the public record.
In scattered places, a small fraction of people report a persistent low hum. The reports are difficult to aggregate, difficult to instrument, and easy to mishandle.
FAL's position is narrow. The phenomenon should be measured locally, compared against environmental and industrial sources, and discussed without ridicule or romance. Unmeasured experience is not data, but it can be a reason to set up an instrument.
A better order of operations
- Take the report seriously enough to document time, place, duration, and conditions.
- Measure the local environment before proposing a source.
- Compare against ventilation, electrical, traffic, industrial, geologic, and weather-linked candidates.
- Keep personal experience separate from instrument data in the public record.
The difficult part is tone. Dismissing reports makes people less likely to provide useful detail. Romanticizing them produces a different failure, where every ordinary explanation feels like a loss. Neither posture helps the record.
FAL keeps the worldwide hum in the public catalog because it is a difficult case in public measurement. The right institutional response is not to solve it with rhetoric. The right response is to keep the intake standard, measurement standard, and language standard visible.
