Revamped Trojan2 Noise Nuisance Recorder launched to market

Cirrus Research has re-launched its best-selling Trojan noise buy phentermine los angeles nuisance recorder with a host of new innovations included as standard.

The Trojan2 offers a raft of new features and functions added following extensive customer research.

The Trojan2 software has also being revamped to allow measurements to be made over longer periods of time as well as making download of measurements quicker.

“It has been designed to meet the needs of Environmental Health Officers, Housing Associations and anyone who needs to measure, monitor and record noise nuisance,” said James Tingay, Cirrus Research Marketing Manager

“It offers high quality, high resolution audio recording as standard using a 16bit/16kHz uncompressed WAV file. This gives plenty of frequency range (up to 8kHz) and a wide dynamic range (up to 96dB) so audio recordings can handle both high and low levels with no loss of quality.”

Another key feature is the Wireless remote control and 4GB memory. This is usually more than enough for most applications but it can be expanded with a 32GB option.

“With the AuditStore function in 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,” added James.

Other noise monitoring must-haves included on the Trojan2 are Pre & Post Trigger options for audio recording that can be set as needed. The pre-trigger can be up to 30 seconds and post-trigger up to 60 seconds.

All the software provided is licence-free with NoiseTools supplied as standard, free of charge and without any installation or licensing restrictions. This means customers can install it on to many desktops, laptops or servers as necessary at no extra cost. Updates are also free of charge.

The Trojan2 is designed to be mains powered with secure cables, but it will switch to its own internal batteries if the mains power is lost. Another important feature is that when power is restored, the noise nuisance recorder will start up again and continue to operate. The Trojan2 will automatically restart when the mains power is restored even if its internal batteries are flat.

“We believe that the Trojan2 is the best and most versatile noise monitoring product out there right now. The feedback we are getting from users is unanimously positive and the new features are making the business of noise monitoring easier, quicker and more accurate.”

Other modifications to make life easier for the end user include:

  • 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

The Trojan2 is designed, manufactured & supported in the UK and backed by a 15 year warranty



The software is a key part of the Trojan2 system and provides the ability to download measurements and recordings, view data and replay audio files directly from any PC. The measurements are stored in a simple tree structure so information is easy to find and data can be tagged with a place, person or project to organise the information for later analysis.

If necessary, replaying the audio recordings through speakers, NoiseTools has a calibration system built-in that lets the customer adjust the levels to accurately represent those at the time of the recording. NoiseTools can also be used with noise measurements and audio recordings made in either Noise Nuisance mode or Hand-held mode and provides a powerful set of tools to view, analyse and store information.
