The VK152A and VK151A Vehicle Noise Measurements Kits include everything you need to make sound level checks on car, motorcycle and truck exhausts. As the kit is designed specifically for vehicle noise measurement, the sound level meter has a mode that takes the average from three measurements as required by ISO 5130 similar standards.
As the kit includes a microphone extension cable and remote measurement button, the processes of setting up the microphone and making the measurements can be done by a single person. The operator can sit in the vehicle controlling the engine speed while starting the measurement and averaging process at the same time.
The standard VNK152A and VNK151A Vehicle Noise Kits include the following parts:
This is not a data logging meter so no software is needed.
Vehicle noise measurements are generally carried out in line with the ISO 5130 standard and other similar measurement standards. In this case the microphone should be positioned 0.5m from the exhaust outlet at an angle of 45°. The engine is brought up to the speed specified by the standard (it varies a little for different vehicles) and a measurement is made. This is repeated three times and the sound level meter calculates the LArep as required.
A 0.5m stick with 45° template is included with the kit to assist quick and correct positioning of the microphone.
Once the microphone is in place, the operator can sit in the driver's seat, controlling the engine revs and operating the sound level meter at the same time.
This Vehicle Noise Measurement Kit includes an Optimus Yellow sound level meter. This will be either the CR151A or CR152A depending on whether you choose the Class 1 or Class 2 version.
This meter is ideal for use in any other applications that need a hand-held non-logging sound level meter. It can be easily removed from the Vehicle Noise Kit for use in other areas.
You can find out more about this sound level meter on the Optimus Yellow web page.
If you need a higher specification sound level meter for other applications then please have a look at either of the following kits:
