Cirrus Research is pleased to announce the launch of the new version of the Trojan Noise Nuisance Recorder, the Trojan2.

Designed specifically for the measurement and monitoring of noise nuisance, the Trojan2 is quick and simple to setup and gives you the all of the noise measurement data and audio recordings needed to effectively assess noise complaints.

The original Trojan was designed using feedback from existing customers and users of noise nuisance recorders and we incorporated a range of features and functions that these users requested.

The new version of the Trojan, the Trojan2, adds even more functions and features including:

• Quicker and simpler removal of the cables for transport and storage
• Less cables to connect to the sound level meter
• More space in the case for storing accessories
• A simple way to add a wired hand switch if needed

We’ve also made a number of updates to the software inside the Trojan to allow measurements to be made over longer periods of time as well as making download of measurements quicker.

Key features of the Trojan2 Noise Nuisance Recorder

Quick, simple and easy to set up

When you are deploying a noise nuisance recorder, it’s vital to know that you’ll get good quality recordings and noise measurement data. With the Trojan2, there’s no need for step-by-step instructions as it’s just a matter of plug in, calibrate and you’re ready to go.

If you forget to press start, the instrument will automatically start measuring after 10 minutes.

Fixed cables

Once the case is locked, the power cable and microphone cable are fixed so there’s no risk of the cables being pulled out either accidentally or deliberately.

The worst thing that can happen is that the power cable is pulled out just after you’ve left so that you only get a few hours data until the batteries go flat. The Trojan2 avoids these issues whilst maintaining the ease of use demanded by our customers. The cables can be quickly removed for transport and storage so there’s no risk of damaging the cables during transport or storage.

High quality, high resolution audio recording

The standard audio recording on the Trojan2 uses a 16bit/16kHz uncompressed WAV file.  This gives you plenty of frequency range (up to 8kHz) and a wide dynamic range (up to 96dB) so your audio recordings can handle both high and low levels with no loss of quality.

This is vital if you want to capture both low levels at night and higher levels during the day (such as doors banging or music playing) and be able to clearly identify what was the source of the noise.  There’s also no risk of overload or under-range in your measurements or audio recordings.

There’s an option to store audio at 32bit/96kHz quality for the ultimate in fidelity and this may be useful if you are going to use the sound level meter out of the case.

4GB memory

Each Trojan2 is supplied with a 4GB memory as standard. This is usually more than enough for most applications but it can be expanded with a 32GB option. We don’t use removable memory cards as there’s a risk that they can be lost, corrupted or damaged.

With the Trojan2 you can also guarantee the chain of data from the instrument to the software, a useful feature if you need to present measurements and recordings as evidence.

Pre & Post Trigger options

The pre and post trigger times for the audio recording can be set as needed. The pre trigger can be up to 30 seconds and the post trigger can be up to 60 seconds. Both of these can be disabled if your procedures require it but you get full control over what suits you best.

Licence free software

The NoiseTools software is supplied, as standard, free of charge and without any installation or licencing restrictions.  You are free to install the software onto as many desktops, laptops or servers as you need and there’s no extra cost.  Updates are free of charge as well so there’s no on-going cost with the software.

Designed, Manufactured & Supported in the UK

The Trojan2 has been designed and manufactured by Cirrus at our factory in North Yorkshire from where we provide the support, training and backup direct to our customers.

This means that if you have any questions, you can speak to the team who designed the Trojan2 as well as having direct access to your sales contacts as and when needed.

15 Year Warranty

All of our noise measurement equipment is backed by our 15 year warranty.  Each time your instrument is calibrated by us, we’ll extend the warranty by a further 12 months.

Don’t forget that our warranty covers accidental damage as well as all of the accessories and options supplied with the kit.

This means that if you damage a cable and your instrument is under warranty, you’ll get the replacement free of charge.
