The SoundEar 3 Noise Processor mounts on the wall to monitor and record the sound levels. The digital display usually shows the current sound level, but this can be switched off or even set to display the time.
The SE3-320 Noise Processor is part of the SoundEar 3 range of products. It is technically identical to the SoundEar 3, but without the display.
Its purpose is to continuously monitor the sound levels, recording the sound level for download to a computer via memory stick. It can also be linked directly into an existing process control system via the 4-20mA Current Loop or the DC output.
The SE3-320 Noise Processor has a large internal memory, to which it can store various sound level parameters every second. It can store the Fast or Slow sound level with "A" or "C" frequency weighting. You can select whether it stores all of these parameters or just the ones you need. When you plug a memory stick in the SE3-320 will automatically transfer the measurements on to it. You then plug the memory stick into your computer to load the measurements into the SoundEar software.
For even longer term storage the SE3-320 can be set to store the measurements directly to a memory stick that is left plugged in, giving an almost unlimited storage time.
The SE3-320 can be linked in to existing monitoring and process control systems, or you can develop your own monitoring system, using either the DC output or Current Loop output.
The SE3-320 has two outputs that can be configured to output the Fast or Slow sound level, either "A" or "C" weighted, or the LAeq value integrated over 1 minute, 15 minutes or 1 hour. For more information please visit the Software page.
The digital display on the SE3-320 usually shows the current sound level, updating every second. However, it can be set to any of the following:
Turning the display off or displaying the time can be useful to avoid people making noise just to see the display change.
