The actual measurement position often differs to the loudest posi-

tion of the live event. Thus the correction value k1 is the correction

value of L

between the loudest position and the actual

measurement position, measured using pink noise. The correc-

tion value k1 is measured or manually set in the page K

SET of the

sound level meter function.

Application: Measurements in accordance with SLV

Actual Sound Pressure Level

SPL with A frequency weighting and F time weighting, compen-

sating for human hearing perception at lower sound pressure lev-

els; applicable at levels lower than 100 dB.

AFmax

Maximum Sound Pressure Level

Measures the maximum environmental noise level during the

measurement period.

AFmax

dt Maximum Sound Pressure Level “delta t” in report

Maximum level of the preset logging interval in the LOG-menu,

e.g. 1 second.

AFmin

Minimum Sound Pressure Level

Measures the minimum environmental noise level during the

measurement period.
