The Trojan2 is a new Noise Nuisance Recorder that has been specifically designed for EHO’s and Housing Associations. We’ve included all of the functions and features that are essential and removed anything that makes life complicated.

Noise Nuisance PassedSimple set up with intuitive screen instructions and automatic startup

When the Trojan2 sound level meter is connected to the case, it is automatically setup ready for deployment as a noise nuisance recorder. Just connect the microphone, plug in the power supply, switch on and calibrate.

 That’s all there is to do.

The Trojan2 is ready to go and even if you don’t press the start button, it will start measuring after 10 minutes so there’s no risk of you forgetting to set the unit running. Give the remote control to the user and tell them to press Record when they hear the noise.


Noise Nuisance PassedAll of the information you could ever need, presented quick and simply

We’ve configured the Trojan2 to give you the data that you really need. You’ll be able to see a graph of noise vs time (logged down to 10ms if needed), the overall Leq, LAE and LAFmax along with any recordings made.

Just click on a recording to listen to the audio and click again to see any additional data such as 1:3 Octaves.

Dig deeper to see the detailed time history data, mark the graph to identify noise sources and print data for use in reports and analysis.

The NoiseTools software gives you the information you need right at your fingertips with the capability to dig into the data and get the information that you want. And don’t forget that NoiseTools is supplied free from any licencing or installation restrictions.

Noise Nuisance PassedCompact size for discreet installation

Only 30cm long, the Trojan2 is small, lightweight and easy to deploy. You don’t even need to unplug the cables when you’re finished. Pick up the case, put it into the carrying case and go.

Noise Nuisance PassedWireless remote control for simple operation by the user

The Trojan2 uses a simple wireless remote control to start and stop audio recordings so there’s less risk of cables being damaged.
