Norsonic was the first company to introduce sound recording of noise events in a sound level meter. This greatly improved the work to identify a noise event and to judge whether it should be excluded or not from the overall noise level. However, it’s quite time consuming to listen through numerous sound recordings.
The three-dimensional Nor1297 Noise compass significantly reduces time spent on judging if a noise source should be a part of the overall noise calculation or not, simply by defining which direction the noise is coming from. When used together with Norsonic’s sound level meters and NorCloud, the device provides a three-dimensional vector pointing at the sound source. The system may also operate off-line and collect the data on the instruments SD card for later analyse in NorReview.
Why should I get the Noise compass?
NorCloud is a Norsonic system to collect, display and process sound level data.
When used together with a Norsonic Sound Level Meter, you can, measure, analyse and report directly from your web browser.
Create projects, assign sound level meters to projects and configure settings such as audio recording, SMS/e-mail alarms and automatic reporting.
NorCloud stores your data safely and conveniently, but you are of course free to download your measurements.
Look at the LAeq noise in both scatter and surface plot. The plots are generated for the timespan selected in the time series plot.
NorReview is a Norsonic desktop application for advanced analysis. Import measurements to do analysis according to several international and national standards.
You can use the software to edit and annotate your measurements, calculate new functions. NorReview supports advanced report generation and customization of reports using Microsoft Excel.
NorReview is widely acknowledged for its high flexibility and advanced functionality.
