The SoundEar 3 is a data logging noise sign and comes complete with software to configure, download and display the results.
The software is included with the SoundEar 3 at no extra charge. It is designed for all recent versions of Windows. It communicates with the sign via the computer's USB port. Downloads and configuration can be carried out via a memory stick, so you don't have to take the sign down from the wall each time.
With a SoundEar 3 connected to the computer's USB port, the software can show the sound levels in real time.
To download historic measurements it is not necessary to connect the sign to the computer. You can plug a standard USB stick into the sign and it will automatically transfer all its measurements. With the memory stick connected to the computer the SoundEar software will now download the measurements. In the image above you can see the sound levels graphed over a 24 hour period.
The SoundEar 3 stores noise measurements in its internal memory. You can configure it to store a minimal amount of information for longer, or to store everything for a shorter period of time. For example, storing the "A" Weighted Slow Sound Level every second will fill the internal memory in just over 90 days. Storing the "A" and "C" weighted Fast and Slow Sound Levels will fill the memory in just under 5 days.
Not enough? You can configure the sign to store the measurements directly to a memory stick, giving almost limitless storage times.
The SoundEar software can configure the sign's digital display (the red numbers in the middle) to show:
Although the default is to show the sound level, it can be useful to turn this off if it causes confusion (not everybody understands dB) or if it causes people to make noise to see how loud they are!
You can use the software to set trigger levels and times for each of the lights - green, yellow and red. For each of the three lights you can set:
You can also have another set of triggers for night time, in case you have an environment, such as a hospital, where the acceptable sound levels are lower at night.
Using the software you can set the output from the sign to be either a DC level (0 to 10V) or current loop (4-20mA) for integrating into other logging and monitoring systems. You can also set the minimum and maximum sound levels that are then mapped onto this DC or current loop output.
If you have a Sound Level Calibrator and need to ensure the accurate operation of the SoundEar 3 then the software deals with this. Connect the SoundEar 3 to the software, connect a microphone extension cable and fit the calibrator to the microphone. The software Microphone Calibration option will then deal with the process of checking and adjusting.
