- Line / Paragraph: https://github.com/corona-warn-app/cwa-documentation/blob/master/images/risk_calculation/risk_calculation_enf_v2_overview.pdf dB values
- Question:
- What was the basis for the dB thresholds in the risk assessment?
- How were these dB distance relationship values calibrated?
- Should a person who is 4m away for 5 hours indoors be a zero risk contact?
- Even if the distance is further should a very long duration contact be a zero risk contact? Indoors time means risk regardless of distance (within reason)
I have found that I could sit an entire day in a small office in about 4m distance from a colleague and the 79dB threshold would never be exceeded (in strength). Even if I were to occasionally be closer to that person it is unlikely that the ENF will scan at exactly that moment. This would lead to the improbable risk assessment that being 4m away from an infectious person indoors for an entire day has no risk of infection and I would not be warned should that person test positive.
