The noise level distribution charts show that the background noise (defined by the L90 noise parameter) was approximately 1 dB lower than in previous years whereas the median noise level (L50 parameter) was only marginally lower.  There have been no noise complaints recorded by Falck during 2025.

During December most deviations on the noise traces resulted from local noise source vehicles, polices sirens, dogs, aircraft but there were suspicious incidents on 30/12/25 00:36 LISTEN,  31/12/25 00:34 LISTEN and 1/1/26 01:30 LISTEN  which could well have originated from Wilton Site.  The third of these slightly exceeded 60dBA for a period of about 30 minutes and might well have resulted in complaints had there not already been excessive noise from New Year fireworks.

Only one triggered audio recording related to a possible site incident again possibly a relief valve discharge - 18/11/25 at 02:43 LISTEN .  

The night time sound level traces do appear to show some significant disturbances particularly on the evening of the 18/11/25 and the following morning but the audio files show these to be due to heavy downpours. 

As the end of the year approaches it would seem that there has been a slight fall in the night time noise levels compared with previous years.

Local noise events - residents, vehicles, weather and the occasional owl are the main cause of audio event triggers but there was one very brief incident on 17/10/25 at 01:34 which probably emanated from Wilton Site - maybe a relief valve discharge?   LISTEN

Otherwise all night time noise levels were normal during October with traces showing effects of heavy rain and blustery wind.

 

COMMENTS 7/10/25

The effects of weather, (wind and heavy rain)  are evident on the night time noise traces but there is no evidence from either the time traces or the triggered audio recordings of any noise disturbance from Wilton Site.

 

COMMENTS 3/9/25

Again there was no evidence of night time disturbance from Wilton site during August and all data is in line with historical data.

 

COMMENTS  6/8/25

July noise monitoring data all in line with historical data and there was no evidence of night time disturbance from Wilton Site.

 

COMMENTS 7/7/25

Monitoring data for June matches the long time base data for the Grange Estate location.  Triggered event audio recordings were almost entirely local, or other off Site noise sources although there are occasional short events which might be due to sudden venting on Wilton site.  An example can be found via the link on the Time History web pages.

 

COMMENTS 2/6/25

The charts indicate little if any change in the general night time environmental noise at Lazenby Grange Estate.  Many events were triggered during the month but the audio recordings revealed these to be almost entirely due to weather, noisy vehicles, aircraft, police car sirens and local activities.  There was however one short event involving banging which most likely came from Wilton Site.  This occurred on the 29th May at 01:26.  Whilst interesting it will have had negligible impact.  (Listen via link on time history sheet.)

 

COMMENTS 6/5/25

The noise monitor was away for calibration for a period of 18 days during April and so only limited data has been acquired during the month.  There has been no evidence of disturbance from Wilton Site in the data that was acquired - including the triggered audio clips.

 

COMMENTS 8/4/25

No night time impact from Wilton site has been identified during the March monitoring period.   The sound level distribution curves remain essentially unchanged from previous years.

 

COMMENTS 3/3/25

The sound level distribution curves show an increase in level compared to previous years but this results from the limited amount of data recorded so far for 2025 and the significant weather events that occurred in February.  There were no events during February that could be sourced to Wilton Site.

 

COMMENTS 4/2/25

All audio recordings triggered during January revealed either vehicle or weather related noise events.  Particularly heavy rain was experienced from 2:15 onwards on the 27th Jan.  This was responsible for the event shown on the time history traces at this time.

The distribution curves show a deviation which indicates an overall increase in noise levels compared to the annual data but this is not unusual for the time of the year and the limited data so far accumulated for 2025.
