Introducing new nuisance noise monitoring equipment can be challenging for Local Councils, Housing Associations and Environmental Health Officers. You can have large teams working over multiple locations and at different times. That’s why we’ve come up with a simple training solution for your team and the Trojan2噪声滋扰记录器。
Covered in this Video:
- What’s included with the Trojan2噪声滋扰记录器
- How to connect all the cables and set-up the equipment
- Setting the time and date correctly
- How to calibrate the Trojan2噪声滋扰记录器
- What you need to do before starting a measurement
- Why you should make a test recording before leaving the equipment

“Getting started with the Trojan2 Noise Nuisance Recorder
在此视频中，我们将介绍Trojan2 Noise Nuisance Recorder的设置和部署。
When you deploy the Trojan, you’ll need to make sure that you’ve got all of the essential components to hand. You’ll have the need the following items.
- The main box
- The acoustic calibrator
- The microphone and preamplifier with a tripod mount
- A remote control
- A small tripod which we’ll use to hold the microphone and preamplifier
- The foam windshield
- A padlock to secure the case
Connecting up the Cables
The black part is the adaptor that allows the microphone to be connected to a tripod.
Now gently turn the locking ring to pull the two parts together until the locking ring is finger tight.
Do not force the connectors together and don’t over tighten the locking ring. You need to be able to take these apart when the measurement is finished.
Take the mains power supply and plug it into a socket and switch it on.
The sound level meter in the box will start up when the power is switched on.
After a few seconds the display will show a number that will be moving up and down.
If it doesn’t press either the right or left arrow keys to change the display.
Setting the Clock
The next thing that we need to do is check that the clock in the sound level meter is correct.
Everything that the instrument does is stamped with the time and date so it’s important that this is set correctly.
At the bottom of the screen you can see the time and date that the instrument is currently reading.
If this is correct we can move onto calibration.
If it’s not correct, press the menu button.
Setting the time and date is similar to your mobile phone. You can use the up and down keys to change the value and the left and right arrow keys to move between the numbers.
When you’ve got both the time and date set, press OK and then press Back to go to the main screen.
Calibration of any noise measurement instrument is very important and even more so with equipment like the Trojan.
You need to be certain that the equipment is working correctly and that any information recorded is accurate.
To calibrate the instrument, take the acoustic calibrator from the main box.
This unit has a button on the end that lets you switch it on and off.
If the green light does not show, you will need to change the battery in the acoustic calibrator.
Gently push the microphone into the hole on the end of the acoustic calibrator.
The green light will light up and the sound level meter will show around 94 dB.
Press the calibrate button on the sound level meter. The screen will go blue.
Press OK on the sound level meter.
Press the button on the acoustic calibrator to switch it off.
Very carefully pull the microphone from the calibrator and put the calibrator back into the case.
We can put the microphone and preamplifier onto the tripod now.
The microphone should now be positioned where it will be left for the duration of the measurement.
它是一个好主意,麦克风的照片rophone has been placed so that you can be sure it has not been moved during the measurement.
It’s also a good idea to reinforce to the user that the equipment should not be moved at all and that if they do accidentally move it or something happens to the power, they should record this on their log sheet.
Getting Ready to Make a Measurement
Close the case of the main box and lock it using a padlock.
Making a Test Recording
Press the start button and the red light on the remote control will flash.
The red Record light on top of the main box will flash and then stay on. The sound level meter is now recording an audio file.
Press the square button on the remote control to stop the recording. The sound level meter is still measuring and storing the noise level information.
What you say at this point is up to you but this information can be very useful when playing back the recordings as it can allow you to check that the user understood what was required of them before you leave the equipment.
The Trojan also has pre and post trigger functions that allow it to capture information from a period before and after the user presses the Start and Stop buttons.
How these function works can configured in the NoiseTools software and they can be very helpful in providing effective recordings and identifying the source of the noise.
When you come back to collect the equipment the green power light should be on.
It can be a good idea to make another recording to state the time and date that the measurement was ended.
Press the triangle key on the remote control to start a recording.
When the red Record light shows you can say the time and date and any other information that may be useful later.
The sound level meter has a sensor to measure the ambient light which helps it to save power.
As the case has been closed for some time, the display may be off.
Behind the keys are lights and these will be flashing once a second to show that the screen is in power saving mode.
Press the Stop button to end the measurement. Press the Exit key to go back to the main screen.
把挡风玻璃从麦克风和护理fully push it into the hole on the calibrator.
Switch on the calibrator and press the calibrate button.
Wait for the calibration to complete and press the OK button.
Carefully remove the microphone from the calibrator.
Switch off the calibrator and put it back in the case.
Press and hold the power button on the side of the sound level meter to switch it off.
We need to put the microphone and preamplifier back into the box and this needs to be done carefully.
When the locking ring has been loosened, the connector will come away from the preamplifier.
Close the box and put the accessories away in the carrying case or rucksack as needed.”
