Vehicle Noise Measurement Kits

These vehicle noise measurement kits are based around the Optimus sound level meter and include everything you need to measure the sound levels from an exhaust as defined by the ISO 5130 Measurements of sound pressure level emitted by stationary road vehicles standard.

A positioning template is included to help position the microphone at the correct distance of 0.5m from the exhaust at the correct angle of 45°. A microphone extension cable and remote control button make it possible for a single person to carry out the tests alone.

  • Optimus sound level meter
  • Microphone extension cable
  • Remote trigger button
  • Positioning template
  • Sound level calibrator

Which Meter?

The vehicle noise measurement kits can be supplied with any of the sound level meters from the Optimus range. All meet the requirements of ISO 5130 and all meet the requirements of IEC 61672 and ANSI S1.4 to either Class 1 or Class 2.

For stationary exhaust noise measurement most regulations demand the use of a Class 1 sound level meter, which is the more accurate version. They also require you to check the meter's function using a sound level calibrator, so one is included in these kits.

Our Recommendation

For basic exhaust noise measurements in line with ISO 5130 we recommend the Standard Model as it has everything you need.

If you prefer to have a data logging meter, maybe you are using it for other noise measurement applications too, then the Integrating, Logging version is a better choice. If your other applications involve environmental or community noise assessments then the Environmental model includes the extra noise measurements that are needed.
