Class 1 Sound Level Meter according to IEC 61672 ÜBERSICHT Soundbook with siNoise is an officially calibratable dual-channel sound level meter according to IEC 61672 (PTB type approval 21.21/09.02). The instrument features separate windows conforming to the above standards for each measurement channel of the sound level meter and is located on a protected partition of the computer, i.e. the software and the setup cannot be changed by the user. The included real-time 1/3 octave analyzer and level recorder windows are not type-approved features of this instrument.
