Noise Nuisance Software The software that is included with the SV215 Noise Nuisance Recorder provides you with the following main features: View the noise levels graphically - Leq, Min, Max, etc. Clearly see the parts that have an audio record Listen to the audio record Print the results in a graphical or tabular format Export data to Excel or Word Create WAV files of audio for further analysis or to email to others Use cursors to calculate noise levels for selected section View periodic noise measurement summaries

Software Overview

Four steps to viewing the noise levels and listening to the recording:

1. Open the data file

The sound level meter stores two types of file:

• Logger and audio - this is the most interesting for the noise nuisance recorder, as it contains the time-history data (seen in the graph above) and the audio recordings.
• Noise measurements - not always needed for noise nuisance assessments, but if you need parameters such as the hourly Leq then these can be stored here.

2. View meter settings

The table shows items such as the meter's serial number, measurement time and date, type of measurements made (Min, Max, etc), frequency weightings and calibration status. This type of information is useful for future reference, in case you need to check the settings of the meter at the time of measurement.

3. View graph of noise levels The most useful display in most circumstances and the best way to navigate around the file. You can zoom in and out and use the scroll bars to move to different times of day. A cursor on the graph can be used to select areas of interest. The software will calculate the Leq inside and outside the selection.

4. Listen to recordings

Periods that have an audio recording associated with the are indicated on the graph with a red bar, as seen in the image above. Move the cursor to the recording of interest and use the playback controls to listen on your computer's speakers.

Reporting

Simple reports can be printed including most of the graphs and tables that are available on screen. For more customised reporting, the tabular and graphical data can be exported to programs such as Word and Excel, or to CSV file for importing into many other programs.
