disturbance to them, their dogs and the numerous geese that would create noise if woken. Noise levels at this location were representative of noise levels at the property. During the monitoring period, the noise was dominated by the hum from the substation. A crackle noise from the nearby pylons was also audible and owls “hooted” at regular intervals. Patches of mist were noted on the fields around the monitoring position.
Location MP2 – Hill Farm House NGR: TM 090 465 15.
The daytime monitoring was undertaken at the access point to a field adjacent to the dwelling. The noise levels in the area are dominated by a mixture of: traffic, audible on distant roads and passing the monitoring location; movement of trees; and aircraft. Although visible, no noise was audible from the substation, approximately 750m to the east of the monitoring location. Passing vehicles generated the highest noise levels.
16. Night-time monitoring was conducted in the same location as in the daytime. No traffic passed the monitoring location and only a hum from the substation was audible.
Location MP3 – Burstall Hall, NGR: TM 102 450 17.
Receptor CS3 is on a public footpath at the southeast corner of Burstall Long Wood. This is to the east of Burstall Hall, the desired receptor location, to which access was not available at the time of the survey as this is on private land.
18.
The noise level at the location is dominated by the sound of distant traffic to the south. The wind in the trees was also a contributing factor. During the last ten minutes of the survey a crop duster began passing the site spraying fertiliser on a field. As such the survey was terminated early.
19.
The night survey was conducted at a location on a nearby public road for security reasons. No traffic passed the monitoring location, however traffic on other nearby roads was noted to be the primary noise source in the area. The noise level at this night-time location is considered representative of that at the residence, and no noise from the existing substation was audible.
20. Measurement results are presented below.
