High DB in calibration screen even in silent room

[markjay]

My room is totally silent. But for some reason, the calibration meter inside REW is reading very high DB 86.8 . if the SPL meter in my hand reads 80 Db, the REW calibration screen will read like 115 DB . I have never had this happen before. Somewhere it is picking up noise, but not from my room. then when I make a measurement, my SPL meter reads 80 DBFS but rew reads -46.8 DBFS.level low. I’ve never had this happen before.

Any ideas?

You need to calibrate the reading.
