Upgrade your SoundSign to become a data logging unit by adding the SoundSign Data Logger and USB Software. The Data Logger simply plugs into the SoundSign Master Unit and collects noise levels (dB(A)) over long periods of time.

You can pre-programme the Data Logger to start recording at a specific time and date, and you can also configure it to take measurements at either 1, 2, 10 or 60 second intervals.

When the Data Logger is plugged into a PC the software will display a graph of the recorded noise levels and allow the data to be printed, exported, and annotated for reference. This allows you to undertake noise monitoring and keep a track of noise levels over time where you signs are placed.
