General Guidance
Positioning your MK:427 Noise Sensor
Every site and application is different but here are some basic guidelines for effective positioning of
your Noise Sensor:
It is usually worth conducting a noise survey, or referring to measurement data from a
recent noise survey to understand the noise profiles for the area.
Install the sensor at a location nearby to where the environmental noise is most likely to
cause annoyance to neighbouring residential areas or other sites.
Legislation often specifies where measurements should be made, for example at property
boundaries or at a complainant’s property.
Try to mount the unit away from obstacles and building walls.
The microphone should always be a minimum of 1.2 – 1.5m above the ground level.
Avoid, where possible, overexposed areas where high wind speeds will affect the noise level
readings.
