Noise Compass
Noise Monitoring
with direction
Why should I get the Noise Compass?
Measure sound pressure as usual
Use Norsonic sound level meter or noise monitoring station to monitor the sound pressure level of a site.
Add dominant source detection
Add the Noise Compass to your setup and measure the direction of the dominant noise source, in all three dimensions.
Avoid listening - save time!
The Noise Compass allows you to mark and filter out sources outside a region of interest. The nearby railway or passing airplanes can be detected automatically, no need to listen to verify.
Calculate sound levels for the site
Sound incident from directions not inside your definition of a site can be automatically marked and excluded from the measurement. The result is Leq or Lden values based on your site definition only.
Hardware
8 MEMS microphones
An array of 8 MEMS microphones ensures full 3D sound incident detection.
Single Ethernet cable
The unit receives power and sends data to Nor145 and Nor150 via a single ethernet cable.
IP55 rated
The unit is fully weather protected for harsh outdoor monitoring.
Norsonic compatible mounting
Fits all existing outdoor microphones. The Noise Compass simply adds inn below the mic assembly.
A-weighted
The noise is preprocessed with A-filters.
100 ms Profile
The Noise Compass delivers data ten times a second.
Smooth in time
Directional data is exponentially smoothed in time to provide high precision indication.
Impulsive when necessary
The Noise Compass also handles impulsive sounds down to 10 ms duration.
Quality ensured
The Noise Compass provides a quality indicator to avoid false detection.

Browse measurements
Show your measurements as a function of time, and see the instantaneous direction.
Analyse
Check the noise distribution over a timespan in surface and scatter plots.
Define sectors
Create your own sectors to automatically generate markers on your measurements.
Report
Let NorCloud automatically generate reports in the interval you specify.
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.
