Data Explorer is a PC-based software application with a powerful data processor for easy and fast analysis of sound level measurement data. Visualize, analyze and control millions of data points with this tool that is dedicated to acoustic consultants and noise measurement professionals. It provides a convenient way to view and manage your data and quickly create customized reports.

Features
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.
Level Statistics
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, Arrêté du 23_01_97 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.
Rating Level
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, 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 1, 2, 5, 10, 15, 30, or 60 minutes.
Measurement Report
Complete your professional reports with customized titles and comments. The Data Explorer automatically adds relevant header data such as the measurement date, calibration information, instrument setup etc., and compiles a tailored report. Simply add your own company logo.

As a research laboratory invested in supporting communities through real time noise monitoring, I am very happy to exclusively use NTi instruments. Not only are the robust, easy to use, and provide high quality data, the customer service is outstanding and their team will work with you to find the most cost effective and appropriate solutions needed for problems ranging from easy to difficult.
Erica D. Walker MSc, ScD, RGSS Assistant Professor of Epidemiology, Brown University School of Public Health
I’ve been using the XL2 for over 15 years for short-term and long-term measurements in all kinds of indoor and outdoor environments all across the country. The meter gets me what I want, when I need it. It’s not only the best value for acoustical measurements, it’s the best tool period. I bet my company and reputation on XL2 results and it has not let me down. You would be crazy not to consider adding NTi instruments to your toolkit.
Herb Singleton, P.E., INCE Bd. Cert., President, Cross-Spectrum Acoustics
We at Constructure GmbH use two XL3 sound level meters for noise monitoring during demolition work. We are very satisfied with these highly user-friendly instruments, the online monitoring in the MeasurEye Cloud, the good advice and qualified support. Factory calibrations at NTi Audio are also handled very smoothly and without complications.
