 thanks!

neutral  Alexander Demyanov: why would directivity be measured in +/-?//If they did mean "directivity" then they are definitely wrong using +/-: http://www.record-producer.com/learn.cfm?a=2704

agree  Tony M: I rather felt the same, and the variation of +/- 3 dB would be logical enough

Explanation:
Looks like it to me. The sound pressure calculated at 10m is only an estimate; the real pressures is + or - 3dBA of that estimate.
