What this source contributes.
The authors report droplet-size responses that depend on frequency and sound level. Reported response thresholds support further metrology review, not rainfall efficacy. Limit: Abstract reports 1,680 sets; Methods 2.3 reports 840 groups and >300,000 readings. Their accounting relationship is unresolved; none is accepted as independent n.
selected main text. Abstract and Methods sections 2.1–2.3. Run allocation, independent preparations, serial dependence and the relation between abstract sets and methods groups are unresolved. Review date: 2026-10-13. AI-assisted source check; not independent replication.

This is a bounded reading note. It is not independent replication, a full systematic review or an endorsement of every conclusion in the paper.
Questions to take to the paper
- Which wet sizes contribute most to attenuation?
- Does a change persist after temperature, humidity and inlet conditions are accounted for?
- Is the measurement representative of the volume people need to see through?
A simulation, chamber result, field observation and operational outcome answer different questions. Record the comparator, measured quantity and conditions before carrying a result into a design.
