Level View with Audio Playback
The chart view shows the logged levels, audio player, spectrogram and frequency spectrum. Mark areas of interest in the graph with a text description and eliminate unwanted noise sources from your final result using "Exclude Markers". The marked areas are summed and appear in your report.
Flexible Data Analysis
A drop-down menu allows you to select the individual levels displayed in the chart. Select one or more, or a range of one-third octave bands for display against time. The fast zoom and pan response over the entire data log period allows for quick data analysis, even with very large data sets. Audio recordings are time-aligned to the graphs. Listen to the recordings for a more objective analysis of the noise sources with manual or automatic gain control.
The software provides a detailed statistical analysis of the logged sound level measurement data. The percentiles can be calculated for wide band levels as well as 1/1 and 1/3 octave band levels. Data Explorer calculates the level statistics of the complete measurement or marked time periods as part of the post-measurement analysis. Excluded periods are considered.
Tonality and Impulsiveness Detection
Generate automated markers based on levels, tones, impulses or time periods in accordance with the ISO 1996:2-2017, BS 4142:2014, DM 16 marzo 1998 and other standards. Each marked period may be exported into a new project for further evaluation by third parties.
Calculate the FFT based on a recorded audio file for an objective audible assessment of tones in noise in accordance with the engineering methods described in ISO 1996:2-2017, DIN 45681 and BS 4142:2014.
Data Explorer calculates the rating level Lr with automated penalties for tone, impulsiveness and nighttime in accordance with the BS4142, DIN 45645, and the Italian DM 16 marzo 1998 standards. The day-night levels Lden, Lden, Ldn, Lday, Levening, Lnight are also available.
Audit Interval Levels
The tabular representation shows all results in a structured and intuitive way. It lists the marked periods and the final result for direct export to Excel. Additionally, Data Explorer divides the noise level data in audit intervals with selectable length of 5, 10, 15, 30, or 60 minutes.
