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?
Keep the evidence attached to its setting.
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.
