Sound level meter using on-ear microphones
The manual control feature enables the Verifit to be used as a sound level meter to perform C-weighted, A-
weighted or 1/12th octave analysis of sound as measured by the probe and reference microphones. A and C-
weighted measurements are limited to frequencies above 100 Hz and the averaging time and update rate are 384
ms.
