The Noise logger is based upon the SINUS Tango sound level meter. The Tango meter is fitted inside a pelican case with a lithium battery and the microphone is fitted to an external tripod. An optional 10m long microphone cable is also available.

Noise data may be downloaded directly to a PC via the Tango_Utilities software in csv format.
