24 2 Program concepts

 Measurement initiated by a complainant.
 Occupational safety
 Determining the sound power

2.1.3 Selected performance features
 Parallel representation of percentile level trends with Leq and bar max
levels
 Optimization of measurement duration and quality assurance of the
measurements by means of online percentile confidence intervals
(according to Dr. Heiß)
 Zooming, scrolling, scaling, cutting out areas, finding and marking events
 Fast evaluation in accordance with TA Lärm 98 under consideration of
all required parameters, determination of the evaluation level,
comfortable reporting function
 Extensive marking functions

 Parallel recording of audio wave files
 Parallel recording of image files (jpeg) by means of USB camera
 Simple determination of evaluation levels
 Two channels can be measured in parallel, e.g., two noise level meters at
COM 1 and COM 2 or simultaneous evaluation of several measurement
variables in case of one-channel measurement (“Dual mode” option)
 Quantification of the measurement uncertainty of percentile levels, online
percentile confidence intervals, determination of the optimum
measurement duration (optional)
 Integrated noise separation process for separating system noise and
external noise according to Dr. Heiss (optional)
 Noise level measurements via a digital interface
 Noise level measurement via sound card
 Importing wave files and generating the noise level trend
 Quantification of the measurement uncertainty of percentile levels
 Hiding of interference levels and of interference and external noises
