Untouched first video … with every hand a device …. This meter has a turntable with steps of 60, 70, 80 , 90, 100 … to 120 (that's when you start recording under a Boeing 747). I start measuring in the kitchen in the 60 DBA range, when I open the (double glazed) window, the meter out of the 60 area … I then switch to the 70 range.
