Sonate Oct class 2

From simple sound level measurement to real-time frequency analysis, the Sonate Plus Oct class 2 sound level meter covers most applications and provides a solution for the improvement of noise pollution.

It meets the latest international standards and has been designed for ease of use. The built-in memory stores the noise level information which is then transferred to a computer and processed by the LDB23 software.

The SONATE Oct class 2 sound level meter has the following applications:

  • Environment
  • Noise monitoring and emergences
  • Industry
  • 1/1/ octave noise spectrum
  • Machine noise and noise rating (NR) curves
  • Process monitoring, conformity check
  • Noise at the work station

 

Main measured values

  • weighted noise level: LXY
  • equivalent continuous level LXeq
  • peak pressure level: LUpk
  • noise exposure level: Lxe
  • Real-time analyser by 31.5 Hz to 8 kHz octave bands
  • Values and graphical representation of NR comfort criteria
  • Maximum, minimum and peak values
  • Statistical distribution of the measured values: L01-L10-L50-L90-L95

 

I/O interface

  • Detection of sensitivity levels for alarm activation
  • DC analogue output: 0-10V: 0-137dB

 

Audio recording on threshold

  • Audio recording on detection of LXeq or LCpk levels – Sampling: 12 kHz – 16 bits; total recording time: 45 minutes – file format*.wav
